Answer:
x=-1 or 5 or 2
Step-by-step explanation:
x³-6x²+3x+10=0
(x+1)(x-5)(x-2)=0
x+1=0 ⇒ x=-1
x-5=0 ⇒x=5
x-2=0 ⇒ x=2
X=4
You have to distribute the negative sign for everything in the parentheses. After that you add x to the other side then add 8 to the opposite side to move them. Then your answer is 4.
3x-6=9 is your equation x=5
Step 1: Add 6 to both sides
Step 2: Divide both sides by 3
80 feet
you would do 8*10 to get the total area so the length *width
37.5 m/s
