1. is 9
and the other ones i dont really know
Distribute the .15 on the right side to get:
20 + .5x + 3 + .075x
Then, combine like terms (add numbers together and add x terms together):
.575x + 23
...and that's your final answer!
First do 3 times 2 which is 6
That we need two numbers that multiple to get 6 and add to get 7
1 and 6
So then we plug them in
(3x^2+6x)(1x+2)
Then we take out what we can
3x(x+2)1(x+2)
Then we check to make sure the parenthesis are the same
They are so we re write
ANSWER
(3x+1)(x+2)
Answer:
(2, 11)
Step-by-step explanation:
Set them equal:
8x-5=4x+3
4x-5=3
4x=8
x=2
Plug x=2 to any of the two equations:
y=4(2)+3
y=11
