Like terms are terms that have the same variable and/or "pesty" numbers.
2y^3 and 4y^2 are like terms, so are y and y^3, since they all contain the variable, Y.
Answer:
13 inches
Step-by-step explanation:
Perimeter is all the sides added so your equation would be 8+8+x+x=42 then you combine like terms. 16+2x=42. Next you would isolate the variable 2x=26 and the divide the 2 on both sides and you get x=13. Meaning your width is 13 inches long

Answer:
y = 2x - 20
Step-by-step explanation:
Simplfy 2 (x-1)
y + 18= 2x - 2
move all terms contain "y" to the left side
y = 2x - 20
Y - y₁ = m(x - x₁)
y - 5 = -8(x - 2)
y - 5 = -8(x) + 8(2)
y - 5 = -8x + 16
<u> + 5 + 5</u>
y = -8x + 21
