The area of a rectangle is 70 square inches and the length of the rectangle is 3 inches longer than the width.
the area of a rectangle is found by multiplying the length times the width.
which equation models this situation?
w(w+3)=70w(w+3)=70
w + 3 = 70
3w = 70
w + 3w = 70

I hope this helps you

width w

length w+3

Area=width.length

70=w. (w+3)

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
