Answer:
11x²y³ - 4xy²
Step-by-step explanation:
remove the parenthesis and collect like terms
4x²y³ + 2xy² - 2y + 7x²y³ - 6xy² + 2y
= (4x²y³ + 7x²y³) + (2xy² - 6xy²) + (- 2y + 2y)
= 11x²y³ - 4xy² + 0
= 11x²y³ - 4xy²
Answer:
3.77
Step-by-step explanation:
A= L × W
52=(W + 10)W
52= W^2 + 10W
0 = W^2 + 10W - 52
Factor from here using quadratic formula to find the roots:
W = 3.77
or
W = -13.77
Dimensions of a shape cannot be negative, therefore it's approximate width is 3.77yd.
