Answer:
27
Step-by-step explanation:
2h+11=65
2h= 65-11
2h=54
then divide both side by two to find h
Answer:
N = 18
Step-by-step explanation:
The triangles are similar, thus the ratios of corresponding sides are equal, that is
= 
( cross- multiply )
5N = 90 ( divide both sides by 5 )
N = 18

Answer:
1600
Step-by-step explanation:
As you can see, this is a difference of squares. We can plug it into our differences of squares formula to get the answer:
(a+b)(a-b)
(58+42)(58-42)
(100)(16)
= 1600
Hope you learned something!
Answer:
880 in³
Step-by-step explanation:
L = 20, W = 10, H = 8
2(h × W) + 2(h × L) + 2(W × L)
= 2(8*10) + 2(8*20) + 2(10*20)
= 2(80) + 2(160) + 2(200)
= 160 + 320 + 400
= 880 in³
