This is because one side of the hexagon is half of one side of the square. Therefore, you multiply 8 by 2. 8x2 = 16
really?, 27+2=29, 29 is youre answer.
4
5x - 4 = 16
Add four to both sides
5x = 20
Divide both sides by 5
x = 4
Answer:1. X=2 y=4
2. X=2.5 y=3
3.x=0 y=-1
Step-by-step explanation:
1. 6x=12
x=2
replace
4+y=8
y=4
2.
8x=20
x=2.5
replace
5+3y=14
y=3
3.
-6y=6
y=-1
replace
x=0
Answer:
Step-by-step explanation:
(4a - 3)/(3b + 1) = 39/(a + 1) You are not going to get a numerical answer for this. Cross multiply
(4a - 3)(a + 1) = 39(3b + 1)
4a^2 + a - 3 = 117b + 39
4a^2 + a - 42 = 117b
b =
