Answer: 8

Step-by-step explanation:

1. Rewrite the equation:

-2x^3 - 3x^2 + 4     x = -2

2. Plug in the value of x, -2

-2(-2)^3 - 3(-2)^2 + 4

3. Use order of operations (PEMDAS):

-2(-8) - 3(4) + 4

= 16 - 12 + 4

= 8

What exactly are you looking for?

Answer:

1) congruent

2) corresponding angles

3) 3x+21 = 6x-60

4) x =9

Step-by-step explanation:

1) congruent becuase supplementary means that these 2 angles add up to make 180 degrees.

2) the file below

3) we know they are equal because the congruent correspoding angles.

4) 3x+21 = 6x-60

=> 21 = 9x-60

=> 81 = 9x

=> 9 = x

Answer

4

Step-by-step explanation:

135/40=3.37 so 4 buses are needed

Answer:

4 busses are needed. Well 135 students going on a field trip and each bus holds 40 students. There can’t be “half” a bus but instead you can have a bus thats not all the way filled. Plus youc an’t duplicate or divide the a light of children so 4 busses.

Step-by-step explanation:

40x ≥ 135

Solve that and the answer has to be a whole number greater then the proposed decimal.

135/40= 3.375

3.375 and it can’t be rounded down and only up to the nearest whole digit so round it to 4.

4 busses.

Answer:

26%

Step-by-step explanation:

To find the percentage of a number, I find it's often helpful to first write it as a fraction:  [tex]\frac{104}{400}[/tex] .

Percentages can be represented as a fraction by putting them over 100, eg. 25% is [tex]\frac{25}{100}[/tex]

.

Therefore, to get [tex]\frac{104}{400}[/tex] into a percentage, we need to change that 400 on the bottom to 100. How do we do that? Divide by four. However, anything we do to the bottom of a fraction, we must do to the top, so we divide both by four:

[tex]\frac{\frac{104}{4} }{\frac{400}{4} }[/tex] = [tex]\frac{26}{100}[/tex]

As we saw earlier, if a fraction has 100 at the bottom, then the top of the fraction is the percentage. So 104 is 26% of 400.

Answer:

?

Step-by-step explanation:

Presumably, x is standing in for the question mark.

The pair of vertical angles (DFE and CFV) shown here both have measure 125°. This angle measure is equal to the average of the measures of the arcs intercepted by the chords CE and DV.

So we have

angle DFE = 1/2 (arc CV + arc DE)

125° = 1/2 (x + 200°)

250° = x + 200°

x = 50°

Answer:

82

Step-by-step explanation:

add 7 to 5 fifthteen times

If Clipner had 15 days to prepare her seventh grade class for their next math exam. On the first day. she gave the class 7 math problems to

complete. Each day following, Ms. Clipner gave the class 5 more math problems to solve in preparation. Then 82 problems did Ms. Clipner give

the class for review

Two or more expressions with an equal sign is called as Equation.

By given data, On the first day. she gave the class 7 math problems to complete. Each day following, Ms. Clipner gave the class 5 more math problems to solve in preparation.

We need to find how many problems did Ms. Clipner give

the class for review .

=7+15(5)

=7+75

After adding 75+7, we get

=82

Hence 82  problems did Ms. Clipner give the class for review.

Answer:

13/20

Step-by-step explanation:

you count up all the marbles together, which is 20 and then count up all the other marbles besides blue, which would be 13 of the 20 marbles are not blue

1. 4.5 cm

2. 25.13 inches

3. 78.54 cm

4. 13 cm. 6.5 +6.5

Radius is half the diameter

Step-by-step explanation:

1) Radius = Half of Diameter

[tex]r = \frac{1}{2} d \\ r = \frac{1}{2} \times 9 \\ = 4.5cm[/tex]

2) Given r = 4 in.

Circumference of Circle =

[tex]2\pi \: r \\ = 2\pi(4) \\ = 8\pi \: cm[/tex]

3) Given r = 5 in.

Area of Circle =

[tex]\pi {r}^{2} \\ = \pi {5}^{2} \\ = 25\pi {cm}^{2} [/tex]

4)Diameter = 2x Radius

[tex]d = 2r \\ = 2 \times 6.5 \\ = 13cm[/tex]

Note for questions 2 and 3 I will leave answers in terms of pi as the question did not specify to leave the answer as what. You can use your calculator to evaluate them if needed.

The equation -10x + 34 is the simplification for the given expression.

Here it is important to remember the rules for the  addition of integers numbers:

+  +   Add  Final result (+)  

-   -   Add  Final result (-)  

+  -   Subtract  Final result (the sign of the integer having a greater value )

-   +  Subtract  Final result (the sign of the integer having a greater value )

The rules for multiplication of numbers are:

     The result presents a positive sign (+) because the signs are same.

    The result presents a negative sign (-) because the signs are different.

First, you should apply the distributive property and the multiplication sign rules.

(x-4)(x-7) + (3-x)(2+x)

x²-7x-4x+28+6+3x-2x-x²

After that, you should simplify the previous result from addition or subtraction sign rules.

x²-11x+34+x-x²

-10x + 34
