12. CCSS Justify Conclusions Gary is painting a decorative box with the dimensions shown at the right. A can of paint covers about 25 square feet. Does he have enough to paint the rectangular faces of his box with three coats of paint? Justify your answer. 778 Chapter 10 Volume and Surface Area​

answer: x=3 and y=4

step-by-step explanation:

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
