125 - 8 = 5³ - 2³ =
= ( 5 - 2 ) · ( 5² + 5 · 2 + 2² ) =
= 3 · ( 25 + 10 + 4 ) = 3 · 39 = 117
Answer:
A ) Difference of Cubes
Answer: A
Explanation:
Just use substitution because it's more efficient. Plug -2x-8 into y to make -2x-8=3x+2. Add 8 to both sides to get -2x=3x+10. Subtract 3x to both sides to get -5x=10. Divide -5 to both sides to get x=-2. Now, plug in x=-2 to one of the equations, let's use y=3x+2. The equation would be y=3(-2)+2. Multiply 3 and -2 to get -6. Add -6 to 2 and you'll result with y=-4.
Answer:
the answer is 9×9 and -9×-9
(x – h)² + (y – k)² = r²
Fill in the variables
(x – 4)² + (y – 4)² = 25
