Dave had 421 blocks tom had 384 blocks and jane had 656 blocks how many more blocks do dave and jane have them tom

149

Step-by-step explanation:

Well first, add the amount of Dave and Tom's blocks together. 421+384=805. Then subtract Jane's amount from Dave and Tom's. 805-656. That should get you your answer. 149.

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.
