Answer:
a) 14x+6
b)12
+9x
c)Perimeter= 118 Area=840
Step-by-step explanation:
a) 2*length+ 2*width---> 2(4x+3)+2(3x)=8x+6+6x= 14x+6
b)length* width---> 3x(4x+3)= 12+9x
c) Perimeter----> 14(8)+6= 118
Area--->12(
)+9(8)=840
Answer:
2, -2
Step-by-step explanation:
f(x) = 2x + 1
g(x) = x - 3
To find g(f(x)), you need to put f(x) into g(x).
g(f(x)) = (2x + 1) - 3
g(f(x)) = 2x + 1 - 3
g(f(x)) = 2x - 2
Your answer will be 2 and -2.
Answer:
