Answer:
21^2 − 14 − 7
Step-by-step explanation:
(3+1)(2+5−7)
(3x+1)({\color{#c92786}{2x}}+{\color{#c92786}{5x}}-7)
(3x+1)(2x+5x−7)
(3+1)(7−7)
(3x+1)({\color{#c92786}{7x}}-7)
(3x+1)(7x−7)

3/8 remain you have to reduce the second fraction so they both have the same denominator. then you can add them.
Start from (19,8), take 2 minutes to travel 8 blocks back, end at (21,0).
Step-by-step explanation:
Easy
sub since boht equal y, both are equal
6x+4=y=4x-2
6x+4=4x-2
minus 4x
2x+4=-2
minus 4
2x=-6
divide 2
x=-3
sub back
y=4x-2
y=4(-3)-2
y=-12-2
y=-14
solution in (x,y) form is
(-3,-14)
