Answer:The radius is one half of the diameter in measurement. The radius measures the distance from the very center of the circle to any point on the circle. You can calculate either of the measurements if you have the circumference of a circle.
Step-by-step explanation:
Answer:
Step-by-step explanation:
Side A is the longest side
Side B is half of A = A/2
Side C is 8m less than A = A-8
Perimeter of traingle = A+B+C
52 = A + A/2 + A-8
Collect like terms
52+8= A+A/2+A
60 = 5/2 A
Divide 60 by the coefficient of A
60÷5/2 = A
60×2/5= A
A=24m
Substitute the value of A into the expressions for sides B and C
Side B =A/2=24/2=12m
Side C =A-8=24-8=16m
The sides of the triangle are 24m, 12m and 16m
Just plug in the values. Use PEMDAS
2(4)^2 - 5(3)
2(16) - 5(3)
32 - 15

Hello!
You solve this like an algebraic equation
You first distribute the 4 and 2
4x - 20 = 2x - 20 + 2x
Combine like terms
4x - 20 = 4x - 20
subtract 4x from both sides
-20 = 0x - 20
Add 20 to both sides
0 = 0
This means that there are infinite solutions to the equation.
Hope this helps!
