Answer:
So each side length is 4s+6
Step-by-step explanation:
Since we know the triangle is an equilateral triangle, we know the perimeter of the triangle is given by since all the sides are the same length
P = 3s where s is the side length
12x+18 = 3s
Divide each side by 3
12x/3 + 18/3 = 3s/3
4s +6 = s
So each side length is 4s+6
Answer:
8
Step-by-step explanation:
−4(−2)
A negative times a negative is positive, 4*2 = 8

Answer:
Let's solve for x.
4x+5y=7
Step 1: Add -5y to both sides.
4x+5y+−5y=7+−5y
4x=−5y+7
Step 2: Divide both sides by 4.
4x/4=−5y+7/4
x=−5/4 y+ 7/4
Answer: for the first one x=−5/4 y+ 7/4
3x−2y=−12
Step 1: Add 2y to both sides.
3x−2y+2y=−12+2y
3x=2y−12
Step 2: Divide both sides by 3.
3x/3=2y−12/3
x=2/3y−4
Answer:
x=2/3y−4
Step-by-step explanation:
Use the Circumference Formula of a Circle: C=2(pi)(r). The radius is the length from the center to a point on the circle. The circumference is essentially the perimeter of the circle, so the “edge” around the circle is the circumference.
