3yds of fabric costs $7.47
1yd of fabric costs $2.49
3yd+2yd=5yd
5yd*$2.49=$12.45
Step-by-step explanation:
3y2 - 48
So the least common multiple is 3
3( y2 - 16)
y + 4 there cannot be a multiple of y
X^2 - 7x + 12 = 0
x^2 - 4x - 3x + 12 = 0
x (x - 4) -3 ( x - 4) = 0
(x - 4) (x - 3) = 0
x = 3 , 4
Check the answer by plugging in 3 and 4 for x, if the equation equals zero then you have your answer.
