A carpenter had a piece of wood that was 12 feet in length. If he needs only 8 5/12 feet of wood, then how much wood should he cut?

it has the same slope and a different y-intercept

hope this : )

m∠a is 90°

m∠b is 40°

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
