Answer: -3p^2-8p-3

Step-by-step explanation: By distributing we get, -3p^2-6p-2p-3. Then simplify accordingly.

To figure out this problem, we need to break down the steps:

-3p(p + 2) - (2p + 3)

because -3p is next to the equation in parentheses, (p + 2), you should multiply -3p into both p and 2

-3p x p = -3p² (if you multiply a variable (p) by another of the same variable with no power, it becomes squared)

-3p x 2 = -6p

so the first part of the equation went from -3p(p + 2) to -3p² -6p

and the second part of the equation has no multiplying to do

so now we add like terms!

-3p² -6p - 2p + 3

-3p² -8p + 3

order from greatest power to least power (first goes the number/variable with the highest power, then the term with a variable, and lastly the number. Right now it is currently in the correct order).

-3p² -8p + 3 is your final answer

Answer:

Step-by-step explanation:

4u - 8u = -63 + 15 ( collecting like terms)

-4u = -48

u = 12

Answer:

u = 12

Step-by-step explanation:

4u - 8u - 15 = -63

Step 1: Combine 4u and -8u

-4u - 15 = -63

Step 2: Add 15 to both -15 and -63

-4u = -48

Step 3: Divide both -4u and -48 by -4

u = 12

Answer:

y = -3x + 30.

Step-by-step explanation:

The slope of line = (9- (-3)) / (7 - 11)

= 12/-4

= -3.

We use the point-slope form of a straight line:

y - y1 = m(x - x1)        where m = slope = -3 and (x1, y1) = (7, 9)

y - 9 = -3(x - 7)

y - 9 = -3x + 21

y = -3x + 21 + 9

y = -3x + 30.

-5y = - 55

by dividing both sides by -5

-5y/-5 = -55/-5

y = 11

Answer:

Step-by-step explanation:

Let number of nights spent in both the locations be [tex]x[/tex]

Airfare for Arizona for 2 persons for two way journey = [tex]95\times 4=\$380[/tex]

Airfare for New York for 2 persons for two way journey = [tex]150\times 4=\$600[/tex]

Cost of night spent in Arizona = [tex]150x[/tex]

Cost of night spent in New York = [tex]120x[/tex]

Cost of going and coming back from Arizona = [tex]380+150x[/tex]

Cost of going and coming back from New York = [tex]600+120x[/tex]

Now the costs should be equal so

[tex]380+150x=600+120x\\\Rightarrow 150x-120x=600-380\\\Rightarrow x=\dfrac{220}{30}\\\Rightarrow x=7.33\ \text{nights}[/tex]

The number of nights is approximately 7 at which the cost of the trip becomes equal.

the description is describing SSA, which is NOT a type of congruence.

since the congruent angle is non-included (which means it is not in between the two congruent sides), we can't say for sure if the triangles are congruent.

this is because the third side of the triangle is unknown, and that side might not be congruent to the same side in the other triangle.

Answer:

70 square feet

Step-by-step explanation:

This is because the correct formula for this problem is: base x height

Using this formula, you first have to find the base of the trapezoid. Since the square's  base is 7 ft, and the triangle's base is 3 ft, you add these together and get 10 ft as a base. For the height, you need the square's height which is 7 ft. Then you multiply and get 70 ft.

Step-by-step explanation:

The shaded area shows the region where it is enclosed in sample space S but does not include the subset B.

Hence it is the complement of B. (A)

If event B is a subset of the sample space S, hence the area represented by the shaded part is complement of B

The set is a collection of members and things.

According to the venn diagram given, the whole set including the set B is the universal set.

The part not shaded is not part of the universal set, hence, we name them the complement of a set.

If event B is a subset of the sample space S, hence the area represented by the shaded part is complement of B

Answer:

The zeroes are -1 and 13

Positive value: [tex]x = 13[/tex]

Step-by-step explanation:

Given

[tex]2x^2 - 24x = 26[/tex]

Solving (a): The zeros

[tex]2x^2 - 24x = 26[/tex]

Subtract 26 from both sides

[tex]2x^2 - 24x - 26= 26-26[/tex]

[tex]2x^2 - 24x - 26= 0[/tex]

Divide through by 2

[tex]\frac{1}{2}(2x^2 - 24x - 26) = \frac{1}{2} * 0[/tex]

[tex]x^2 - 12x - 13 = 0[/tex]

Expand

[tex]x^2 - 13x + x - 13 = 0[/tex]

Factorize:

[tex]x(x-13)+1(x-13)=0[/tex]

[tex](x+1)(x-13)=0[/tex]

Split:

[tex]x +1 =0\ or\ x-13=0[/tex]

[tex]x =-1\ or\ x=13[/tex]

Hence, the zeroes are -1 and 13

Solving (b): The positive value of x

In (a) above:

[tex]x =-1\ or\ x=13[/tex]

The positive value is:

Answer:

perimeter = 20.9 units

Step-by-step explanation:

perimeter

perimeter = distance around two dimensional shape

= addition of all sides lengths

distance formula:

[tex]d = \sqrt{( x_{2} - x_{1}) {}^{2} + ( y_{2} - y_{1}) {}^{2} } [/tex]

A(-3,0) B(2,4)

x1 = -3 x2 = 2

y1 = 0 y2 = 4

(substitute the values into the distance formula)

[tex]ab = \sqrt{(2 - ( - 3)) {}^{2} + (4 - 0) {}^{2} } [/tex]

[tex]ab = \sqrt{5 {}^{2} + 4 {}^{2} } [/tex]

[tex]ab = \sqrt{41} [/tex]AB = 6.4 units

B(2,4) C(3,1)

x1 = 2 x2 = 3

y1 = 4 y2 = 1

[tex]bc = \sqrt{(3 - 2) {}^{2} + (1 - 4) {}^{2} } [/tex]

[tex]bc = \sqrt{1 {}^{2} + ( - 3) {}^{2} } [/tex]

[tex]bc = \sqrt{10} [/tex]

BC = 3.2 units

C(3,1) D(-4,-3)

x1 = 3 x2 = -4

y1 = 1 y2 = -3

[tex]cd = \sqrt{( - 4 - 3) {}^{2} + ( - 3 - 1)) {}^{2} } [/tex]

[tex]cd = \sqrt{( - 7) {}^{2} + ( - 4 ){}^{2} }[/tex]

[tex]cd = \sqrt{65} [/tex]

CD = 8.1 units

A(-3,0) D(-4,-3)

x1 = -3 x2 = -4

y1 = 0 y2 = -3

[tex]ad = \sqrt{( - 4 - ( - 3)) {}^{2} + ( - 3 - 0) {}^{2} }[/tex]

[tex]ad = \sqrt{( - 1) {}^{2} + ( - 3) {}^{2} } [/tex]

[tex]ad = \sqrt{10} [/tex]

AD = 3.2 units

= AB+BC+CD+AD

= 6.4 + 3.2 + 8.1 + 3.2

= 20.9 units

Answer:

x = 70°

Step-by-step explanation:

There are two vertical and parallel lines h and i. Also, a transversal line g cuts across these parallel lines. The intersection of the transversal line and line h produces an upper right angle of 70° and bottom left angle of x°.

These angles x and 70 are vertically opposite angles, hence:

x = 70° (vertically opposite angles are equal to each other)

Answer:

The three consecutive square numbers that added together give 149 are 6, 7 and 8.

Step-by-step explanation:

To determine which are the three square consecutive numbers that added together add up to 149, the following calculation must be performed:

1 x 1 = 1

2 x 2 = 4

3 x 3 = 9

4 x 4 = 16

5 x 5 = 25

6 x 6 = 36

7 x 7 = 49

8 x 8 = 64

9 x 9 = 81

10 x 10 = 100

Thus, we can see that 36 + 49 + 64 gives the result 149. Therefore, the three consecutive square numbers that added together give 149 are 6, 7 and 8.
