Answer:
b
Step-by-step explanation:
In a 30-60-90 right triangle, the hypotenuse is twice the length of the short leg.
The hypotenuse is AB and is 18.
The short leg is BC and is 9.
The only choice with BC = 9 is b.
Answer: b
Answer: 16x+3+x214
Step-by-step explanation:
Multiply 2 and 2 to get 4.
4+16x+x214−1
Subtract 1 from 4 to get 3.
3+16x+x214
To add or subtract expressions, expand them to make their denominators the same. Multiply 3+16x times x2x2.
x2(3+16x)x2+x214
Since x2(3+16x)x2 and x214 have the same denominator, add them by adding their numerators.
x2(3+16x)x2+14
Do the multiplications in (3+16x)x2+14.
x23x2+16x3+14
Step-by-step explanation:

Answer:
g(6) = 71
f(11) = 62
Step-by-step explanation:
Let's solve g(6) first
Plug 6 into x
g(6) = 2(6)^2 - 1
g(6) = 2(36) - 1
g(6) = 72 - 1
g(6) = 71
Now let's solve f(11)
f(11) = 5(11) + 7
f(11) = 55 + 7
f(11) = 62
<em>Thus, out answers are 71 and 62 respectively</em>
