If f(x) = 6x , then f(2) = 6(2) or f(2) = 12... simply substitute the argument in for the variable in your expression on the right.
Answer:
6x^2 + 17x + 12.
Step-by-step explanation:
(3x + 4)(2x + 3)
= 3x(2x + 3) + 4(2x + 3)
= 6x^2 + 9x + 8x + 12
= 6x^2 + 17x + 12.
Answer:
first one is simnple cross multiply and divide
12*7=4x
84=4x
x=21
2nd same process but more steps
7x=5(x+8)
7x=5x+40
7x-5x=40
2x=40
x=20
Step-by-step explanation:
The answer is the last one !
