Answer:

Step-by-step explanation:

Anything raise to the power zero is 1

Therefore,

2x² + 4x + 4 + x² + 1 = 180
Tasya [4]

Step-by-step explanation:

2 {x}^{2}  + 4x + 4 +  {x}^{2}  + 1 = 180

3 {x}^{2}  + 4x + 5 = 180

{3x}^{2}  + 25x - 21x - 175 = 0

x \times (3x + 25) - 7(3x + 25) = 0

(3x + 25) \times (x - 7) = 0

3x + 25 = 0 = x - 7 = 0

x =  -  \frac{25}{3}  = x = 7

= x_{1} =  -  \frac{25}{3} . \:  \:  x_{2} = 7

If f(x) = 4x + 3 and g(x) = 3x, evaluate f(x) * g(x) for x= -1/2 a. -3/2 b. -21/2 c. 6 d. 0
grin007 [14]
F(x) = 4x+3
f(-1/2) = 4(-1/2)+3
f(-1/2) = -2+3
f(-1/2) = 1
-----------------------
g(x) = 3x
g(-1/2) = 3(-1/2)
g(-1/2) = -3/2
-----------------------
Replace x with -1/2 to go from
f(x)*g(x)
to
f(-1/2)*g(-1/2)
So you'll multiply the results of 1 and -3/2 to get 1*(-3/2) = -3/2
-----------------------
The final answer is -3/2
