Steps to solve:
-20 < 4 - 2x
~Subtract 4 to both sides
-24 < -2x
~Divide -2 to both sides
12 > x
Best of Luck!
Answer:
Part A- yes, because all 3 sides are Equal (each side is 5)
Part B- yes, each rectangle has the dimensions 12*5
Part C- yes- since the sides are 5 and 12 you can determine that the diagonal is 13, using they Pythagorean theorem 
- true statement, so the lateral sides are rectangles, because the corners are 90
Part D-
(it is a 45-45-90 triangle- so the hypotenuse is the side length times 
Part E- the diagonal face as the largest area- dimensions are 
the area would be 
Step-by-step explanation:
The answer is b for both questions
It should be D. Because the equation is 2(width+ height + length
