Answer:
To find the area of the rectangular sides, use the formula A = lw
To find the area of the triangular faces, use the formula A = 1/2bh,
Step-by-step explanation:
1st formula where A = area, l = length, and h = height.
2nd formula where A = area, b = base, and h = height.

Below is the solution:
<span>E(X) = 50*1 - 3*8000/10000
E(X) = 50 - 24 = $26 per year</span>
So, to factor out the equation x²+12x+35, first multiply the first and last numbers.
1×35=35
So, you need to find the multiples of 35 that add up to 12.
So, you find 7 and 5. These two numbers are the magic numbers that will be used as the correct factored form of x²+12x+35, because:
>7×5=35
>7+5=12
So, using these two numbers, you get your factored form as:
(x+5)(x+7)
212= 2 X 2 X 53
212= 4X 53

Answer:
Step-by-step explanation:
We can subtract the second equation from 4 times the first:
4(a +b) -(4a +1.5b) = 4(95) -(267.5)
2.5b = 112.5 . . . . . simplify
b = 45 . . . . . . . . . . divide by 2.5
a = 95 -b = 50 . . . find 'a'
The solution is (a, b) = (50, 45).
