25.13cm^2 or 8pi. The radius of a circle is 2 x pi x r^2. R is the radius. 2 x pi x 2^2cm -> 2 x pi x 4cm -> 8cm x pi -> 25.13cm^2. Leaving the answer in terms of pi would be 8pi.

Charlize and Camille solved the equation 4x – 2y = 8 for y. Their work is shown
Aloiza [94]

Answer:

The answer to your question is below

Step-by-step explanation:

Equation 4x - 2y = 8 solve for y

First, pass 4x to the right side                -2y = -4x + 8

Pass -2 to the right side                             y = -4/-2 x  + 8 /-2

Simplify                                                        y = 2x -4 or    y = -4 + 2x

I can not see clearly the work of Charlize and Camille, but the one that has the answer shown above is correct.

Triangle is equal 180 degrees. Given values, 70 + 35 = 105
Meaning, you find what ‘more’ degrees are needed to get 180
180 - 105 = 75 degrees
70 + 35 + 75 = 180
x = 75
