1. B
2. B and C
3.C
4.B the answer is 238 but i guess the rounded
Step-by-step explanation:
Answer:
x=3
Step-by-step explanation:
All the angles added together must equal 360 degrees.
74+43+50+37+12x+12x+11x+17x = 360
Simplify the equation by adding like numbers.
204+52x=360
Subtract 204 from both sides of the equation.
204+52x-204=360-204
52x=156
Now, divide both sides by 52.
52x/52=156/52
x=3
Answer:
x=4.5
Step-by-step explanation:
Given the equation
, we simplify as:

#We further simplify as multiples of 9(divide by 9 to solve for x):

Hence, from our simplification the equation has the same value as x=4.5
Perimeter formula
p = 2l + 2w
I reverse left-right side
2l + 2w = p
Move 2l to the right
2l + 2w = p
2w = p - 2l
Move 2 to the right
2w = p - 2l
w = (p - 2l)/2
Summary
p = 2l + 2w
2l + 2w = p
2w = p - 2l
w = (p-2l)/2
