Length of side of new square is 17 inches
Step-by-step explanation:
- Step 1: Let the length of the side of the old square be x. Then length of side of new square = x + 3 and Perimeter of new square = 40 + 2x
Perimeter of a square = 4 × side
⇒ 4(x + 3) = 40 + 2x
⇒ 4x + 12 = 40 + 2x
⇒ 2x = 28
⇒ x = 14 inches
- Step 2: Find length of side of the new square
⇒ x + 3 = 17 inches
combine like terms on the left side. you always go from left to right.
Domain is (-10, infinity) and range is negative infinity, positive infinity.
Since 25/10 is 2.5 I think you can multiply 6 by 2.5 and get 15 so I think it’s about 15/25
