Answer:
6x+20
Step-by-step explanation:
F(x) = 6x+2
f(x+3) means replace x with x+3
F(x+3) = 6(x+3)+2
= 6x+18+2
= 6x+20
Answer:
Its the bottom-right one
Step-by-step explanation:
Have a good day
W=L+2
A=48=L*W
48=L*(L+2)
48=L^2+L*2
0=L^2+L*2-48
L1=6
L2=-8 (can't be used since it's negative)
Lenght=6
Width=8
Answer:
-0.28125
Step-by-step explanation:
Y-x=3
-y-4x=2 (I multiplied this equation by -1 so when I add I can eliminate a variable.)
Now add them together.
-5x=5
x=-1 now plug in x to solve for y
-y-4(-1)=2
y=2 so your answer is (-1,2)
