Can someone please help me with this I’m struggling

Equation:  

x = -10 or x = 7

x = 7 (width can't be negative)

x + 3 = 10

Step-by-step explanation:

Represent the width of the rectangle by  x.  "The length of a rectangle EXCEEDS the width by 3" means the length is 3 LONGER than the width, so the length is represented by the expression  x + 3.

Area = (length)(width)

70 = (x + 3)x

Multiply out the right side.

Factor the left side.

Each binomial could equal 0, so

The negative solution does not make sense as the width of a rectangle.

x = 7, making the length, x + 3 = 10

good job you smart son of a gun you are smarter that einstein. 7

so, converting firstly the mixed fractions to improper fractions and then "adding".
