We have the expression
, note that both terms have the factor 2x, if we factor this out, we are left with:
2x(4x + 5)
If you redistribute it you can see that it equals
Hope this helps! :)
If f(x) = 0 then
solutions
x = 7 , x = -4
hope it helps
B. 15 because
-18+x=-3
X= -3 + 18
X = 15
Answer:
C x=40, y=30
Step-by-step explanation:
Remember the opposite side of parallelogram is the same
so angle C and angle A is the same.
3x=120
divide both sides by 3 and you get 40
All parallelogram equal to 180 degrees so to find y
180=2y+120
-2y=120-180
-2y=-60 negative divide negative is positive.
y=30
