**Answer:**

10%

**Step-by-step explanation:**

That's what I think, I'm not sure. The difference is 5. 5 is 10% of 50. so I think the percent change from the first value to the second is 10%. I hope someone else also answers though, since once again, I'm not sure.

Think of it like this

-3 means move 3 spaces back (or left)

+4 means move 4 spaces forward (or right)

so, from 0, move 3 spaces left

then move 4 spaces right

end up with 1 space right or +1

Answer:

SA = 484 cm²

Step-by-step explanation:

Surface area of the composite figure = surface area of the larger rectangular prism + (surface area of the smaller rectangular prism - base area of the smaller rectangular prism)

✔️Surface are of the larger rectangular prism = 2(LW + LH + WH)

L = 7 cm

W = 7 cm

H = 12 cm

S.A = 2(7*7 + 7*12 + 7*12) = 434 cm²

✔️Surface are of the smaller rectangular prism = 2(LW + LH + WH)

L = 7 cm

W = 2 cm

H = 2 cm

S.A = 2(7*2 + 7*2 + 2*2) = 64 cm²

✔️Base area of the smaller rectangular prism = L*W

L = 7 cm

W = 2 cm

Area = 7*2 = 14 cm²

✅Surface area of the composite figure = 434 + (64 - 14)

= 434 + 50

= 484 cm²

THE CORRECT ANSWER IS N=4
