Answer:
210 + -1x
Step-by-step explanation:
Simplifying
X + (x + -30) = 180
Reorder the terms:
X + (-30 + x) = 180
Remove parenthesis around (-30 + x)
X + -30 + x = 180
Reorder the terms:
-30 + X + x = 180
Solving
-30 + X + x = 180
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '30' to each side of the equation.
-30 + X + 30 + x = 180 + 30
Reorder the terms:
-30 + 30 + X + x = 180 + 30
Combine like terms: -30 + 30 = 0
0 + X + x = 180 + 30
X + x = 180 + 30
Combine like terms: 180 + 30 = 210
X + x = 210
Add '-1x' to each side of the equation.
X + x + -1x = 210 + -1x
Combine like terms: x + -1x = 0
X + 0 = 210 + -1x
X = 210 + -1x
Simplifying
X = 210 + -1x
Answer:
Step-by-step explanation:
first, 4l=2 x π x radius............................ eqn 1
next, find the value for the radius, r using
Area of a circle=πx radius squared
61.6=3.142 x r x r
61.6÷3.142=r x r
r x r= 19.6
r=4.43
then substitute the value of r in eqn 1
4l=2 x 3.142 x 4.43
4L=27.83812
L= 27.83812÷4
L≈6.96
area of a square = L x L
=6.96 x 6.96= 48.43
