Clara writes the equation (x – 13)(x + 8) = 196 to solve for the missing side length of a rectangle represented by the factor x + 8. what is the missing side length represented by x + 8 units of the rectangle?

The length of the rectangle is 28 units.

Step-by-step explanation:

It is given that the length of the rectangle is x+8 units.

The given equation is

Using distributive property,

Subtract 196 from both the sides.

Using zero product property,

At x=20, the length of the rectangle is

At x=-15, the length of the rectangle is

The length of the rectangle can not be negative.

Therefore the length of the rectangle is 28 units.

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)
