Step-by-step explanation:
I did this one too but i don't if they changed the answer good luck I would double check
distribute the 8 to the 5 and x. then distribute 11 to 9 and x.
(40+8x)=(99+11x)
-11x -11x
-3x+40=99
-40 -40
-3x= 59
divide three on both sides
x=59/-3
final answer x=-59/3
Answer:
Step-by-step explanation:
y = -4x^2 + 4x + 6
Factor out the leading coefficient:
y = -4(x^2 - x) + 6
Complete the square:
y = -4(x^2 - x + (½)^2) + 4(½)^2 + 6
= -4(x-½)^2 + 7
Answer:4x+30
Step-by-step explanation:
Distribute 4(5+x) to get 20+4x
So then 10+20+4x
Which is 4x+30
