The product is -10y² -19y +15.
7x9 = 63
63x2 = 126
126 is the surface area
Answer:
50 i think?
Step-by-step explanation:
30 divided by 12 is 2.5, 2.5 x 20 equals 50
Let the two integers be x and x+1
(x+1)^2-x^2=21
x^2+2x+1-x^2=21
2x+1=21
2x=20
x=10
then x=10, x+1
10+1=11
the two integers are 10, 11
This is the notes to finding the parabola
