Answer:
8x² + 8
Step-by-step explanation:
Given
(x² + 3)² - (x² - 1)² ← expand both factors using FOIL
=
+ 6x² + 9 - (
- 2x² + 1) ← distribute by - 1
=
+ 6x² + 9 -
+ 2x² - 1 ← collect like terms
= 8x² + 8
The answer would be 12 to the -10 because with multiplication you you add the -4 and -6
Answer:
The index of a number says how many times to use the number in a multiplication. It is written as a small number to the right and above the base number. In this example: 82 = 8 × 8 = 64. The plural of index is indices. (Other names for index are exponent or power.)

Answer:
$0.75
Step-by-step explanation:
The equation for a circle is (x - h)^2 + (y - k)^2 = r^2
where (h, k) is the center and r is the radius
(x + 8)^2 + (y + 9)^2 = 169
Since the equation is -h and -k, I will rewrite in terms of -h and -k.
(x - -8)^2 + (y - -9)^2 = 13^2
The center is (-8, -9) and the radius = 13
