20=V+9-16
20=V-7
-V=-7-20
-V=-27
27=V
Answer:
(x + 9)(x - 2)
Step-by-step explanation:
x^2 + 7x - 18
-18 = 9 * -2
9 + (-2) = 7
So factor:
x^2 + 7x - 18 = (x + 9)(x - 2)

To find the height of the triangular prism, you will use he formula for finding the volume of a prism and solve for the missing height.
V = Bh, where B is the area of the base.
<u>126</u> = <u>63h</u>
63 63
h = 2 feet
The height of the triangular prism is 2 feet.
Answer:
2√10 / 7
Step-by-step explanation:
to solve cos(sin^-1(3/7))
we break it into simpler terms
sin^-1(3/7) ------ these will be taken as an angle when dealing with cos
sin Ф = opposite / hypothenus = 3/7
Using Pythagoras Theorem
Hypothenus ² = opposite² + adjacent ²
7² = 3² + a²
49 = 9 + a²
a² = 49 - 9 = 40
a = √40 = √2x2x10 = 2√10
cos Ф = adjacent / hypothenus = 2√10 / 7
cos(sin^-1(3/7)) = 2√10 / 7
