To start, first distribute the x's to their expressions. This would look like this:
(x*x+2*x)+(x*x+x*3)=x^2+2x+x^2+3x
Then, you combine like terms or simplify, and you get an answer of 2x^2+5x
Answer:
4. y = 8 - x is the right answer
c is the answer of this question because the case given is necessary
Answer:
A
Step-by-step explanation:
Table A
input is 5 and output is 9
Using the 2 given rules
Increase the input by 4 to get output , then
5 + 4 = 9 ← correct output
Multiply input by 2 and subtract 1 to get output , then
2 × 5 - 1 = 10 - 1 = 9 ← correct output
Table A works for both rules
