Find the value of \mathrm{x}x if \bigtriangleup \mathrm{A}\mathrm{B}\mathrm{E}△ABE and \bigtriangleup \mathrm{C}\mathrm{D}\mathrm{E}△CDE are similar.

(x+3)(x+7)

step-by-step explanation:

it has changed from the width and the height.

step-by-step explanation:

2 1/2 feet

step-by-step explanation:

"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
