Question

2. A square had a side length of 5x units. A triangle has side lengths of 5x, (4x+14), and (5x+4) units, For what value of x, will the square and triangle have the same perimeter?

A 2
B 4
C 5
D 3​

Answer 1

Explanation:

for the square, it's got 4 sides so

4(5x) = 5x + 4x+14 +5x + 4

20x = 14x +18

6x = 18

x = 3

answer D looks good
