Answer:
y = 1 cm
x = 7 cm
Step-by-step explanation:
x = 3y + 4
perimeter = 2 * ( y + x ) = 16
x + y = 8 by using x = 3y + 4
y + 3y + 4 = 8
4y = 4
y = 1
1 + x = 8
x = 7
x=20
3x-10=x+30
2x-10=30
2x=40
1=0 2
3x² + 2x + 3 / b
This is the correct answer. Hope this helps
22/20×100%=110%
110%-100%=10%
Yes
x , y
(-3 , 0)
plug in the numbers
2(-3) + 6(0) = -6
-6 = -6
