Answer:
Step-by-step explanation:
Factoring x2-6x-30
The first term is, x2 its coefficient is 1 .
The middle term is, -6x its coefficient is -6 .
The last term, "the constant", is -30
Step-1 : Multiply the coefficient of the first term by the constant 1 • -30 = -30
Step-2 : Find two factors of -30 whose sum equals the coefficient of the middle term, which is -6 .
-30 + 1 = -29
-15 + 2 = -13
-10 + 3 = -7
-6 + 5 = -1
-5 + 6 = 1
-3 + 10 = 7
-2 + 15 = 13
-1 + 30 = 29
Answer: 7725 square feet
----------------------------------------------------------------------------------------------
Explanation:
Step 1 is to add the two parallel bases together: 125+81 = 206. Afterwards, divide that by 2 to get 206/2 = 103. The last thing to do is multiply that result by the height to get 103*75 = 7725

I believe the answer is 9051$ but this is just my guess.
D - 15.4 million.
59.3m is 56% of 105.89m whereas 51.6m is 57% of 90.52m
105.89 - 90.52 = 15.37
Answer:
Step-by-step explanation:
1) x +22.5 = 49.25
Subtract 22.5 from both sides
x + 22.5 - 22.5 = 49.25 - 22.5
x = 26.75
Checking: LHS = x + 22.5 = 26.75 + 22.5 = 49.25 = RHS
2) 37.2 = n - 12
Add 12 to both sides
37.2 + 12 = n - 12 + 12
49.2 = n
n = 49.2
3) 55t = 176
Divide both sides by 55
