3x+4y=12
9x-2y=15
we will use elimination
multiply 3x+4y=12 by -3
-9x-12y=-36
9x-2y=15
_________ add
-14y=-21
÷-14 both sides
y=1.5
find x
3x+4 (1.5)=12
3x+6=12
-6 both sides
3x=6
÷3 both sides
x=2
x=2
y=1.5
Answer:
Step-by-step explanation:
6.0 , 6.0 , 6.1 , 6.2 , 6.3 , 6.15 , 6.23
hope that help mark me as a brill
A = a^2.....where " a " is the size of 1 side
A = 256
256 = a^2...take sqrt of both sides, eliminating the ^2
sqrt 256 = a
16 = a
so each side is 16 ft....now we find the perimeter
P = 4a....where " a " is the size of each side
P = 4(16)
P = 64.......so they will need 64 ft of fencing <===
