Brayden is simplifying the expression 4n - (n - 3)2. He begins by distributing the negative to the terms inside the parentheses. What should he have done instead?
O combine like terms
O square the binomial
• cube the binomial
O rewrite the expression as a fraction

11

step-by-step explanation:

32.50-7.50=25

225/25=11

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
