Prove that 3a + 3b is equivalent to 3(a + b) when a = 4 and b = 3.

Step-by-step explanation:

= 3a+3b

or, 3×4+3×3

or, 12+9

or, 21

again,

= 3(a+b)

or, 3×(4+3)

or, 3×7

or, 21

hence 3a+3b is equivalent to 3(a+b) is proven

the answer is c.

step-by-step explanation:

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.
