x2 - 12x = -6
Your next step would be to add 36 to both sides.
x2 - 12x + 36 = 30
In completing the square, we divide the term before x by 2, and then square it and add it to both sides.
12 / 2 = 6
6^2 = 36
That would be the next step.
-3/9 is equal to -0.3333333333333
So no, -3/9 is not greater than -0.33
Hope this helps ^-^
27.1739% percent. to find that, all you have to do is multiply 2.5x100. that equals 250. divide this by 9.2, and that is your answer
Answer:
f(-4) = 72, f(x + 5) = 3x² + 23x + 36
Step-by-step explanation:
f(-4) = 3(-4)² - 7(-4) - 4
= 48 - (-28) - 4
f(-4) = 72
f(x + 5) = 3(x + 5)² - 7(x + 5) - 4
= 3(x + 5)(x + 5) - 7(x + 5) - 4
= 3(x² + 10x + 25) - 7(x + 5) - 4
= 3x² + 30x + 75 - 7x - 35 - 4
f(x + 5) = 3x² + 23x + 36
