5a-15+9a=3a+29
We simplify the equation to the form, which is simple to understand
5a-15+9a=3a+29
We move all terms containing a to the left and all other terms to the right.
+5a+9a-3a=+29+15
We simplify left and right side of the equation.
+11a=+44
We divide both sides of the equation by 11 to get a.
a=4
Answer:
Step-by-step explanation:
The sides are in the ratio 1:2:3, so the lengths of the sides are 1x, 2x, 3x.
1x + 2x + 3x = 48'
6x = 48'
x = 8'
The lengths of the sides are 8', 16', 24'
