Answer:

4x^2 - 28x +48

Step-by-step explanation:

you would plug in h(x) into g(x)

(2x-7)^2 - 1 or (2x - 7)(2x - 7) - 1

solve (2x - 7)^2 using the foil method to get

4x^2 - 14x - 14x + 49

combine like terms to get

4x^2 - 28x + 49

now subtract 1 from 49 to get

4x^2 - 28x + 48

Which of the following functions is equal to sin(90° - )?

scZoUnD [109]

Let sin(90° - )------------------------ > sin (90-x)

sin(a - b) = sin a*cos b - cos a*sin b
so
sin(90 - x) = sin 90*cos x - cos 90 * sin x
sin(90 - x) = 1*cos x - 0* sin x-------- > cos x

the answer is the option D. cos()

2x + 12 = -2(4-2x) X=10 X=-10 X=-5 X=5

Greeley [361]

Answer:

$\boxed{x = 10}$

Step-by-step explanation:

$= > 2x + 12 = - 2(4 - 2x) \\ \\ = > 2x + 12 = (( - 2) \times 4) - (( - 2) \times 2x) \\ \\ = > 2x + 12 = - 8 - ( - 4x) \\ \\ = > 2x + 12 = - 8 + 4x \\ \\ = > 2x - 4x + 12 = - 8 \\ \\ = > - 2x + 12 = - 8 \\ \\ = > - 2x = - 8 - 12 \\ \\ = > \cancel{-} 2x = \cancel{- }20 \\ \\ = > 2x = 20 \\ \\ = > x = \frac{20}{2} \\ \\ = > x = 10$
