Answer:
a. 3x = 45
15cm
Step-by-step explanation:
Given the perimeter of an equilateral triangle = 45cm .
Using the equation
3x = 45
Divide both sides by 3
x = 45/3
= 15cm
The length of each side of the triangle is 15cm because an equilateral triangle has its three sides equal

Pythagorean Theorem
Answer:
k=10
Step-by-step explanation:
4k + 12= 52
minus 12 on both sides
4k=40
now divide by 4
k=10
I think it would just me 20 +72m, since it is already simplified
You replace j(X) with x in the equation Y(x)
the answer can be:
Y(j(x))= 6(^3rad(0.11x^-2))
