Answer/Step-by-step explanation:
1. x = -3.6
Add 1 on both sides.
18x = 23x + 18
Subtract 23x on both sides.
Combine like terms.
Divide the answer.
-5x = 18
x = -3.6
2. x = 11/3 (2.66666...)
Add 5 on both sides.
6x = 3x + 11
Subtract 3x on both sides.
Combine like terms.
Divide the answer.
3x = 11
x = 11/3
3. x = 23
Subtract 12 on both sides.
5x = 6x - 23
Subtract 6x on both sides.
Combine like terms.
Divide the answer.
-x = -23
x=23
(that's all.)
Answer:
fgi = 48
fgh = 24
hgi = 24
Step-by-step explanation:
Bisection divides an angle into two equal angles,
So,
4x - 20 = 3x - 9
4x - 3x = - 9 + 20
x = 11
fgi = 3x - 9 + 4x - 20
= 3x + 4x - 20 - 9
= 7x - 29
= 7 ( 11 ) - 29
= 77 - 29
fgi = 48
fgh = 3x - 9
= 3 ( 11 ) - 9
= 33 - 9
fgh = 24
hgi = 4x - 20
= 4 ( 11 ) - 20
= 44 - 20
hgi = 24
Answer:
<h2>J{(0,8),(1,7),(2,6)}</h2>
Answer:
137 in.^2
Step-by-step explanation:
A = nsa/2
where
n = number of sides = 9
s = length of side = 4.7 in.
a = length of apothem = 6.5 in.
A = (9)(4.7 in.)(6.5 in.)/2
A = 137.475 in.^2
Answer: 137 in.^2
