7. C
8.A. sqrt(144)
^^^^^^^^^^^^^^^^^^
The correct answer is 20.
square root 2 times square root of 200 = square root of 400 ans since 400 is a perfect square, then I'll calculate to 20.
42 firefighters in total.
16 volunteered for the special rescue team.
n + 16 = 42
or it could be this way:
42 - 16 = n
There’s are ratio which would be 8/10. 12/x should equally 8/10. So it would be 14 tiles long.
a) second and last one : 32x - 24 and 8*4x - 8*3
b) first and third one : 22y and 7y + 15y
pls mark brainliest!!
