Can someone check if i did this correct. it’s number 4 if you’re wondering.

Step-by-step explanation:

The scale factor for 4 a) is 3/10 and for 4 b) is it 56/48 (I think)

For 4 a) x=30 and for 4 b) x=7

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.
