15% of 45 is 0.15 x 45 or 6.75 feet. That's how far the submarine descended in 1 minute. So, in 4 minutes the submarine would be 4 x 6.75 feet down which is 27 feet.
Like radicals are radicals that have the same root number AND radicand (expression under the root).
And there ya have it!
Happy studying.

This is how you are supposed to do in another question
Y=4 on the first one
A=92 on the second one
Answer:
You would multiply the x component by -2
Step-by-step explanation:
(-2) (-2x-5y)=-2(-1)
4x+10y=2
4x+2y=8
set both equal to 4x
4x=2-10y
4x=8-2y
2-10y=8-2y
-6=8y
y=-6/8
y=-3/4
4x + 2(-3/4) = 8
4x=38/4
x=38/16
x=19/8
