Answer:
h = 24 ft
Step-by-step explanation:
A = 936 ft^2, b = 39 ft.
A = bh
Divide both sides by b:
h = A/b = 936 ft / 39 ft = 24 ft
Answer:
-16b+40b^2
Step-by-step explanation:
-8b*2=-16b
(-8b)(-5b)=40b^2
Add up all the numbers the divide by the amount of numbers in the set.
1199/11 = 109
B. 109 answer
18x^2 + 2x + y^2 = 1
<span>==> 18(x^2 + x/9) + y^2 = 1 </span>
<span>==> 18(x^2 + x/9 + 1/324) + y^2 = 1 + 1/18 </span>
<span>==> 18(x + 1/18)^2 + y^2 = 19/18 </span>
<span>==> (x + 1/18)^2/19 + (y - 0)^2/(19/18) = 1. </span>
<span>By comparing this to the standard form of an ellipse, the center is at (-1/18, 0). </span>
To make a perfect square, we must know that 22/2 = 11. In this case:
(x + 11)^2 = x^2 + 22x + 121
