Answer:
u dont explane the question
Step-by-step explanation:
If you mean 12x by “1and2x”. it’s 9x - 5y = 0.
If it’s 1x and 2x it’s y= 2/5x^2 -3/5x, x
Answer:
The length of each of the 4 sides of a square is the same. Then
5x - 8 = 3x
2x = 8
x = 4
5(4) - 8 = 12
3(4) = 12
The length of each side is
L = 4.
The perimeter is 4 times the length.
P = 4L = 4(4) = 16

Answer: =135
Step-by-step explanation:
f(x) = 6(21)+9
f(x)= 135
I'd help if I could, but unfortunately, this is the one area of math that I suck at.
