The area of a rectangle is 70 square inches. the length of the rectangle is 3 inches longer than the width.
which equation models this situation?
a. w + 3w = 70
b.3w = 70
c. w + 3 = 70
d. w(w+3)=70

Step-by-step explanation:

The area of a rectangle is 70 square inches. The length of the rectangle is 3 inches longer than the width.

your answer is D. w(w+3)=70

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
