Answer: 2908.92435 inches.
Step-by-step explanation for shape 1: A = 2(wl + hl + hw) = 2 · (30 · 13 + 13 · 13 + 13 · 30) = 1,898 inches.
Step-by-step explanation for shape 2:
Using the formulas:
A=2AB+(a+b+c)h
AB=s(s﹣a)(s﹣b)(s﹣c)
s=a+b+c
2
Solving for A:
A=ah+bh+ch+1
2﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=9·30+13·30+9·30+1
2·﹣94+2·(9·13)2+2·(9·9)2﹣134+2·(13·9)2﹣94≈1010.92435
Step-by-step explanation for total volume: 2908.92435 inches.

Step-by-step explanation:
Answer:
The angle between the building and the ladder 
6.9°
Step-by-step explanation:
Given data
AB = 50 ft = length of the building
BC = 6 ft
= Angle between the ladder & building
From Δ ABC
6.9°
This is the angle between the building and the ladder.
Literally any number besides 2, so it could be y=x+1, just change the constant number
Answer:
4 and any number other than 4
Step-by-step explanation:
The first answer is 8. Solve the equation for x.
x-4 = 4-x
To get rid of the x on the right side, you must add x to both sides
(x) + x - 4 = (x) + 4 - x
On the right side x-x=0 so now you are left with 4 on the right side
On the left side x+x=2x so you have 2x-4 on the left side.
Now add 4 to both sides to get rid of the 4 on the left side.
(4) + 2x - 4 = (4) + 4
On the left side, 4-4=0 so you are left with 2x.
On the right side 4+4=8
So now you have 2x = 8. To finish solving for x, you now need to divide both sides by 2.
2x 8
---- = -----
2 2
On the left, 2 divided by 2 equals 1 so you are left with x.
On the right, 8 divided by 2 equals 4.
So now you know what X must equal 4 to make the equation TRUE.
Any number other than 4 will make the equation false.
