Answer:
(c) x² -64
Step-by-step explanation:
The factoring of the difference of squares is one of the special forms we use in the study of polynomials. It tells you ...
a² -b² = (a +b)(a -b)
__
You have a factor (x +8), so a=x, b=8, and the "expanded" form is ...
a² -b² = x² -8² = x² -64
So 15-7 is 8
Here are some things I did:
10-2 or 28-20
Answer:
2x + 3y = 20
Step-by-step explanation:
Slope of the line is -2/3 . We can use any of the given points to find the equation of the line. Lets use (1, 6)
The general point-slope form of a line is:

Here m is the slope which is -2/3
x1 and y1 are the coordinates of the point. So x1 = 1 and y1 = 6
Using these values, we get:

Answer: CD segment
Step-by-step explanation:
Answer:
y=4
Step-by-step explanation:
3(3y − 12) = 0
Divide by 3
3/3(3y − 12) = 0/3
3y-12 = 0
Add 12 to each side
3y-12+12 = 0+12
3y = 12
3y/3 = 12/3
y = 4
