Answer:
x=12
Step-by-step explanation:
Let's solve your equation step-by-step.
2x+8+5x−2=90
Step 1: Simplify both sides of the equation.
2x+8+5x+−2=90
(2x+5x)+(8+−2)=90(Combine Like Terms)
7x+6=90
Step 2: Subtract 6 from both sides.
7x+6−6=90−6
7x=84
Step 3: Divide both sides by 7.
7x7=847
(f – g)(x) = 0
16x-30 -(14x-6) =0
distribute
16x-30 -14x+6 = 0
combine like terms
2x-24=0
add 24 to each side
2x=24
divide by 2
Answer: x=12
Answer: $10.00 + 4.50r
r = rose
$10.00 = delivery charge
$4.50 = charge per rose
2z^3 - 5z^2 + 4z - 1
(2z - 1)(z^2 – 2z+ 1) =
= 2z^3 - 4z^2 + 2z - z^2 + 2z - 1
= 2z^3 - 5z^2 + 4z - 1
