b. If each square has a side length of 61 cm, write an expression for the surface area and another for the volume of the figure

Blababa [14]

Answer:

6*(61^2) and 61^3

Step-by-step explanation:

If the squares have a side length of 61 (assuming this is a cube) our surface area is 6*(61^2) because each side is a square and there are six sides.

As for the volume, we have 61^3.

Hope this was helpful.

Using the Completing the Square method, what are the zeros of the quadratic function f(x) = 2x2 + 8x - 3?

Ipatiy [6.2K]

Answer:

Step-by-step explanation:

1) to rewrite the given equation:

f(x)=2(x²+4x)-3; ⇔ f(x)=2(x²+4x+4)-3-8; ⇔ f(x)=2(x²+4x+4)-11; ⇔ f(x)=2(x+2)²-11;

2) the roots are:

$\left[\begin{array}{ccc}x=-\sqrt{\frac{11}{2}}-2 \\x=\sqrt{\frac{11}{2}}-2 \end{array}$

3) finally, the correct answer is A.

Reagan will use a random number generator 1,200 times. Each result will be a digit from 1 to 6. Which statement best predicts ho

Stolb23 [73]

The answer is B.

The only reason it will be 200 is because the numbers 1,2,3,4,5,and 6 are all an option so the probability of 5 is 1/6 and if you multiply 1/6 by 1,200 you will get 200. Hope this helped!

Which number line shows the solution set for the inequality -4x+7>15

Ira Lisetskai [31]

First, let's simplify the inequality as much as we can:

-4x + 7 > 15
-4x > 8

Divide by -4:
x < -2
