2m + 6 = 2(2m + 3) -2m
2m + 6 = 4m - 2m + 6
2m + 6 = 2m + 6
True.
X³-8=x-2: Original equation.
x³-x-6=0: Subtract x and add 2 to both sides.
(x-2)(x²+2x+3): Factor the equation
x-2=0; x²+2x+3=0: Separate the expressions into equations
x=2: Add 2 to both sides
x²+2x+3=0: Quadratic Formula
x= 2, <u>-2+√-8</u>,<u>-2-√-8</u>
<u /> 2 2
Might be wrong but y=2-2x
ANSWER: 7/6
step 1: Simplify both sides of the equation.
step 2:Subtract 2/3 from both sides.
step 3: Multiply both sides by 7/(-1).
This problem involves using the Pythagorean Theorem which is a^2+b^2=c^2
We already have the values of a and c, but b is unknown. So we plug in: 11^2+b^2=20^2
121+b^2=400
b^2=279
b=sqrt(279)
b=16.7
So the answer is about 16.7 ft
Hope this helped!
