Answer: all of them
Step-by-step explanation:
156-36+36=84/2= 42 <—— the missing length.
Area would be 36x42= 1,512.
Answer:
how much does he earn an hour?????
Step-by-step explanation:
F(x) = -3x² + 6x - 2
First, we make the coefficient of x² equal to 1
f(x) = -3(x² + 2x - 2/3)
Now, we must make the form a² + 2ab + b²
b = 2x/2x
b = 1
f(x) = -3(x² + 2x + 1² - 1² - 2/3)
f(x) = -3(x² + 2x + 1 - 5/3)
f(x) = -3(x + 1)² - 5
The vertex is (-1 , -5)
And this is the maximum point because the coefficient of the squared term is negative.
Answer:
yes they are because its a 90 degree angle
