Answer:
3x + 20 = 80
Step-by-step explanation:
If Sam gets paid $20 a week whether she makes any cakes or not, that is a fixed amount. The amount that she makes will only go up IF she makes cakes. She makes $3 per cake she bakes, and if the number of cakes is our unknown, the expression for that is 3x. Adding that to the fixed amount she makes is 3x + 20. Now we set that equal to 80, which is what she made in a week and solve it for x, which gives us the number of cakes she had to bake to make that $80.
3x + 20 = 80
All squares are equal sides.Let X be the side of a square.Area of square,A = x^2
Here a tile is a square of side length 'x'. The following polynomial represents,
(x - 4) represents "the width of the new tile" (because 4 inches cut from the tile)
4x represents "the area removed from the tile" (since one side of removed tile is 'x' and other is 4 inches.)
x2 represents "area of original tile" of side equal to 'x'
x represents "the length of the new tile" (since length of new tile is not reduced. Length =x and breadth is x-4
