12m²n² -8mn +1
[6mn-1]•[ 2mn-1]
[ 6mn•2mn + 6mn•-1 + -1•2mn +-1•-1]
= [ 12 m²n² -6mn -2mn +1]
= [ 12m²n2-8mn+1]

Answers:
- y intercept: 9
- zeros: -3, -1, 1, 3
===============================================
Explanation:
The y intercept is where the curve crosses the y axis. The curve appears to do so just below y = 10, so y = 9 seems like a good estimate. I'm basing this off of the answer choices given. The y intercept always occurs when x = 0.
The zeros, aka roots or x intercepts, are where the curve crosses or touches the x axis. This occurs in four locations: x = -3, x = -1, x = 1 and x = 3. The x intercepts always occur when y = 0.
Answer:
49x² + 42x + 9
Step-by-step explanation:
Given
(7x + 3)²
= (7x + 3)(7x + 3)
Each term in the second factor is multiplied by each term in the first factor, that is
7x(7x + 3) + 3(7x + 3) ← distribute both parenthesis
= 49x² + 21x + 21x + 9 ← collect like terms
= 49x² + 42x + 9
Your answer should be 314
4 x 16=64
10 x 25 (25 is the height)=250
64 + 250=314
