Mandisa draws a rectangle to represent the area of her yard. The area can be represented by 10x2 – 13x – 14.

andrew-mc [135]

Answer:

(x-2) and (10x+7)

Step-by-step explanation:

10x²-13x-14

10x²-20x+7x-14

10x(x-2)+7(x-2)

(x-2)(10x+7)

the factors are (x-2)(10x+7)

meaning that the length and breadth are (x-2) and (10x+7)

Solve for W when: B = 703 * w/h (squared). Note: w/h is a fraction where h is squared

svlad2 [7]

We are given with the expression B = 703 * w / h^2. To isolate w in the function, we multiply the whole equation by h^2. This results to B h^2 = 703 w. Next, we divide the equation by 703 to isolate w. The final expression of w becomes w = B h^2 / 703
