Find the area of a rectangle with length 7xy^2 inches and width 8x^2y inches?
Alja [10]

To calculate the area of a rectangle, you have to multiply the length by the width. The formula is A = L x W. A is area, L is length and W is width. Replacing the formula with the given -<span>
A = 7xy^2 x 8x^2y;
   = 56X^3y^3
Therefore, the area of the rectangle is </span>56X^3y^3 inches^2 (square inches)

2w^2-11w=-12 <br> a w=3/2 or 4<br> b w=1 or 12<br> c w=1 or 7<br> d w = 2.5 or 6
dlinn [17]
Hey mate !!
Here's your answer !!


2w^2 - 11w = -12
2w^2 -11w + 12 = 0
2w^2 - 8w - 3w + 12 = 0

2w ( w - 4) -3 ( w - 4) = 0
(2w - 3) ( w - 4) = 0

Hence

2w - 3 = 0
2w = 3
w = 3/2

w - 4 = 0
w = 4

Hence value of w are 4 and 3/2

Hope this helps!!
Cheers!!
