Answer:
17 cm.
Step-by-step explanation:
Because 12 cm + 5 cm. is 17 cm.
3(x)-10=x+4. That’s the equation. Ight, now we gotta solve it. It would be 3x-10=x+4, then you subtract 4 from each side, so 3x-14=x, then subtract 3x, so -2x=-14, then divide -2x by -2 and -14 by 2, which means the answer is x=-7. Thank me later.
To solve this, you can do the is over of equals to % over hundred.
