Answer:
Step-by-step explanation:
l= 20 in ; b = 40 in; h = 50 in
Surface Area = 2*(lb+bh+hl)
= 2*(20*40 + 40*50 + 50*20)
=2*(800 + 2000 + 1000)
=2*3800
= 7600 square inches

Answer:
x = -78
Step-by-step explanation:
Write and solve an equaiton of ratios, as follows:
hypotenuse to hypotenuse:
57 51
----------------- = ---------------
2x + 7 x + 4
Cross-multiplying, we get:
57x + 228 = 102x + 351
Combining the x terms on the right, we get:
228 = 45x + 351
Combining the constants on the left:
-123 = 45x, and so x = -123/45 = -78
x = -78
