Answer:

4x-20

Step-by-step explanation:

2+5x-1x-22

First, rearrange to make life temporarily easier.

5x-1x+2-22

Then combine like terms.

5x-1x=4x

2-22=-20

So we have 4x-20

That is simplified as far as it can.

Answer:

60

Step-by-step explanation:

Answer:

The numbers are 6 and 2

6 squared = 36

2 squared = 4

So 36-4 = 32

And 36 x 2 = 72 + 4 = 76

Its b In normal form of a straight line, the equation is given by where p is the perpendicular distance of the line from the origin and  is the angle between the perpendicular line and the positive direction of the x-axis.

Answer:

they do- here's how (i think)

Step-by-step explanation:

a toad has similar features- think about it.

a toad has gills since it needs to stay underwater for the time being

so do fish

they have a tail to let them swim around and direct themselves to which area they're going to.

fish also do the same!

hope this helps!:)

Answer:

  (c)  y=(1/2)(360−152) because you subtract the arc measure from 360° and then multiply by one-half.

Step-by-step explanation:

The inscribed angle y is half the measure of the intercepted arc. That arc is the difference between 360° and 152°. So, y is ...

  y = 1/2(360° -152°)

Answer:

[tex]r=20.1[/tex]

Step-by-step explanation

[tex]C=\pi d[/tex]

Green car circumfrence = 126 feet

Plug in numbers

[tex]126=3.14d[/tex]

Divide both sides by 3.14

[tex]\frac{126}{3.14} = 40.12...[/tex]

Divide diameter by 2 to find radius

[tex]\frac{40.1}{2} = 20.05[/tex]

round up to [tex]20.1[/tex]

Step-by-step explanation:

angle j + angle JKL + angle KLJ = 180(sum of angles in a triangle)

[tex]j + 94 + 41 = 180 \\ j + 135 = 180 \\ j = 180 - 135 \\ = 45[/tex]

Arc Length s =

given r = 10 units,

[tex] = (\frac{j}{360} ) \times 2\pi \: r \\ = ( \frac{45}{360} ) \times 2\pi(10) \\ = 0.125 \times 20\pi \\ = 2.5\pi \\ = 7.85units(nearest \: hundredth)[/tex]

Answer:

7.85 units

Hope this helped and have a good day :D

Answer:

Step-by-step explanation:

Let us try factorizing this polynomial using splitting the middle term method.

Factoring polynomials by splitting the middle term:

We need to find two numbers ‘a’ and ‘b’ such that a + b =5 and ab = 6.

On solving this we obtain, a = 3 and b = 2

Thus, the above expression can be written as:

x2 + 5x + 6

= x2 + 3x + 2x + 6

= x(x + 3) + 2(x + 3)

= (x + 3)(x + 2)

Thus, x+3 and x+2 are the factors of the polynomial x2 + 5x + 6.

(p, q, p+q)

(1, 56, 57)

(-1, -56, -57)

(2, 28, 30)

(-2, -28, -30)

(4, 14, 18)

(-4, -14, -18)

(7, 8, 15)

(-7, -8, -15)

Use those pairs of numbers and their sums to fill in the three columns of your table.

Answer:

1) Factor the trinomial. Show ALL work:

(x-2)(x-3) steps see explanation

2) Factor the polynomial using grouping.

Group and factor out the greatest common factor (GCF), then combine.

[tex](5x-2) (x^{2} +5)[/tex]

4) Choose ONE of the following polynomial and factor completely.

15x2 − 35 = [tex]5 (3x^2-7)[/tex]

Step-by-step explanation:

x2−5x+6

The middle number is -5 and the last number is 6.

Factoring means we want something like

(x+_)(x+_)

We need two numbers that

Add together to get -5

Multiply together to get 6

Try -2 and -3:

-2+-3 = -5

-2*-3 = 6

Fill in the blanks in

(x+_)(x+_)

with -2 and -3 to get...

(x-2)(x-3)

4( Choose ONE of the following polynomial and factor completely,

15x^2-35

35 as 5*7

15 as 5*3

= 5*3x^2-5*7

Answer:

15 x 10 x 20 =

Step-by-step explanation:

Answer:

1,100

Step-by-step explanation:

15*10*2=300

20*15*2=600

20*10=200

300+600+200=1,100

you need to find the surface area which means the area of all the sides except the top(bc i think its open???)

a shortcut i used was multiplying sides that have the same area by 2. for example, the side 15*10, there was another side like that, so i multiplied by two instead of having to solve for the other side individually, does that make sense?

check my math if im wrong

Answer:

area = 84 m²

Step-by-step explanation:

area = (1/2)(4)(3)(2) + (5)(6) + (6)(3) + (4)(6) = 84 m²

Answer:

P = 56.562

Step-by-step explanation:

Perimeter of a semicircle:

P = πr + 2r

Given:

r = 11

Work:

P = πr + 2r

P = 3.142(11) + 2(11)

P = 34.562 + 22

P = 56.562
