B) 16a+20
That’s the answer.
Answer:
the answer is D, 13
Step-by-step explanation:
I just did the assignment
Hi
Just told you : first know by heart remarkable identities !
Then apply :
4x²-12x = -9
4x²-12x +9 =0
(2x-3)² = 0
(2x-3) (2x-3) = 0
Now you have a double solution :
2x-3 = 0
and 2x -3 = 0
I let you try !
For this problem, you must plug 3 into x...
f(x)= -5(3) - 3 + 20=
f(x)= -15 - 3 + 20=
f(x)= 2
Answer:
2+2=4
