Yes, when solving and equation, you always start with the parentheses, then solve the exponents then multiplying and dividing then adding and subtracting.

A cube has a volume of 7 to the 3rd power cubic centimeters . what is its surface area?
cricket20 [7]

This cube has 6 faces, and all side lengths are equal.

The volume of a cube with sides of length L is given by L^3.

The problem says that the volume is 7^3, which means that each side is 7

The surface area of a cube of length L is 6*L^2. Since L = 7, the surface area is:

6*7^2 = 6*49 = 294 cm^2

The radius of a circle is 9 feet. What is the length of a 90° arc?
maks197457 [2]

Answer:

\frac{9\pi }{2} feet, or 14.14 feet

Step-by-step explanation:

Use the arc length formula:

s = rθ

To use the formula, we have to convert the central angle to radians.

90° is equivalent to \frac{\pi }{2} radians, so plug this and the radius into the formula:

s = rθ

s = (9)(\frac{\pi }{2})

s = \frac{9\pi }{2}

So, the length of the arc is \frac{9\pi }{2}\\ feet, or approximately 14.14 feet

What is the vertex?? Please answer QUICK!
astra-53 [7]

Answer:

D

Step-by-step explanation:

To obtain vertex form from the given equation use the method of completing the square

given 8y + x² = - y² - 181 + 26x

rearrange having the x terms and y terms together

add y² to both sides

8y + x² + y² = - 181 + 26x ( subtract 26x from both sides )

x² - 26x + y² + 8y = - 181

add (half the coefficient of the x/y terms )² to both sides

x² + 2(- 13)x + 169 +y² + 2(4)y + 16 = - 181 + 169 + 16

completing the square on both the x and y terms

(x - 13)² + (y + 4)² = 4 → D
