Step-by-step explanation: An equilateral triangle means all 3 sides are the same length.
A square also have the same length for all 4 sides.
So each side of the square is 6cm, to find the perimeter you do 6*4=24.

so each side of the triangle will be 8cm
Answer:
Step-by-step explanation:
Fourths, then b. Sorry if late.
Easy, showing work,
using the method FOIL (First,Outer,Inner, Last)
Take, (x+3)(x+5) and multiply,
First,
x*x=
Outer,
x*5=5x
Inner,
3*x=3x
Last,
3*5=15
Add the terms together,
+8x+15 (
+5x+3x+15)
Thus, your answer.
