The answer is yes it dose
Answer:
81y^4 - 16x^2, difference of squares.
Step-by-step explanation:
So we need to expand the following product:
(9y2-4x)(9y2+4x) = 9y2*9y2 + 4x*9y2 - 4x*9y2 -4x*4x = 81y^4 - 16x^2
And this type of product is the difference of squares.
Answer:
Stayed the same
Step-by-step explanation:
Altogether, there are 8 marbles in the bag (before Keenan adds the other marbles.) The probability so far that he draws a yellow marble is 4/8, or 1/2.
When he adds the marbles to the bag, there are 10 marbles altogether and 5 yellow marbles. The probability now is 5/10, or 1/2.
The probability has stayed the same.

Answer:
- (A) AB = DE and segments with same length are congruent
Step-by-step explanation:
Justification of step 1 is based on the congruence of segments AB and DE.
<u>Therefore correct choice is the first one:</u>
- (A) AB = DE and segments with same length are congruent
Answer:
D. 7 to 3
6+1=7 parts yellow, and the blue didn't change amount, so 7 parts yellow, and 3 blue.
