X = 59, y = 44
2x + 18 + x - 15 = 180
3x + 3 = 180
3x = 177
x = 59
x - 15 = y
59 - 15 = y
44 = y
Yes they are like terms because they are both whole numbers
Answer:
100000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000100
First multiply the first by the first (x*x=X^2)
second multiply the second by the second (4*3=12)
finally the multiply the first by the second and the second by the first then add them together (X*3)+(4*X)= 7X
the answer is:
X^2+7X+12=(X+4)(X+3)
