Step-by-step explanation:

a. Area = 121 ft²

s² = 121

s = √121

Therefore s = 11 ft

b. Area = 81 yd²

s² = 81

s = √81

Therefore s = 9 yd

c. Area = 324 cm²

s² = 324

s = √324

Therefore s = 18 cm

d. Area = 361 mi²

s² = 361

s = √361

Therefore s = 19 MI

The product of two consecutive even positive integers is 674 more than the sum of the two integers. Find the integers.
IrinaVladis [17]
2n(2n+2)=2n+2n+2+674\\
4n^2+4n=4n+676\\
4n^2=676\\
n^2=169\\
n=-13 \vee n=13
-13\not\ \textgreater \ 0

n=13\\
2n=26\\
2n+2=28

It's 26 and 28.

Can somebody pls show me how to solve this?
fomenos

Answer:

C. 52.5

Step-by-step explanation:

The total from W(-20) to Z(120) is 140.

You can add up all of the numbers in the ratio, 2:3:3, to get 8

Divide 140 by 8 to get 17.5

Multiply 17.5 times the number in the ratio for each segment, so the new ratio would be 35 : 52.5 : 52.5

Since you are trying to find segment XY, which was the 2nd number in the ratio, you would get your answer as 52.5
