Solve:
2x - 4(x - 2) = 6x
x = 1
Change this product into a sum (x+5)(2x-3)
2x+7x-15
One: intersecting lines, None: parallel lines, Inf: same line (coinciding)
Give the next 3 terms in this sequence: 1/2, -1, 2...

|2x - 5| = 20
x=-7.5 and x=12.5
Simplify: (2c2 - c) + (-5c3 + c2 - 2)
-5c3 + 3c2 - c + 2
Mark planted a lemon tree. When it was planted the tree was 4 months old and 1 feet tall. The tree grew at a rate of 2 feet each year for 8 years, but those trees typically don’t live any longer than 30 years. What is a reasonable domain for this scenario?
D: 0 ≤ x ≤ 30(ish)
3(x-14) = 17x
x = -3
Simplify: (2x - 9)2
