Well first off if you have a negative sign in front of the seven, DO NOT have a plus sign because it will be confusing. So y-7=13? , You add 7 to 13 and = 20, so y= 20
I’m pretty sure it would be equilateral because all the sides are the same:)
Answer:
20
Step-by-step explanation:
5x4= 20
1×1=1
2×2=4
3×3=9
4×4=16
5×5=25
20 does not not split up evenly like the examples above.
Since .7 is in the tens place you would put 70 0ver 100 as 70/100 which in percent would be = 70%
