Simplify, THEN evaluate for x = 3, y = -4, and z= -2. 7(x - y) - 3(2 + 2x)

Tamiku [17]

Answer: 25

Step-by-step explanation:

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

= 7x - 7y - 6 - 6x

= x - 7y - 6

for x = 3, y = -4

3 - 7(-4) - 6

= 3 + 28 - 6

= 31 - 6

= 25

If the area of a circle is 58 square feet, find the circumference. A. 42.5 ft. B. 4.25 ft. C. 22.35 ft. D. 26.99 ft.

PSYCHO15rus [73]

Answer: OPTION D.

Step-by-step explanation:

The formula for calculate the circumference of a circle is:

$C=2r\pi$

Where r is the radius.

The formula for calculate the area of a circle is:

$A=r^2\pi$

Where r is the radius.

Solve for r from $A=r^2\pi$ to calculate it:

$r=\sqrt{\frac{A}{\pi}}\\r=\sqrt{\frac{58ft^2}{\pi}}\\r=4.296ft$

Subsitute the radius into $C=2r\pi$ . Then:

$C=(2)(4.296ft)\pi=26.99ft$
