-3(u+3)+3(3u+2) simplify

=6u−3

Step-by-step explanation:

Distribute:

=(−3)(u)+(−3)(3)+(3)(3u)+(3)(2)

=−3u+−9+9u+6

Combine Like Terms:

=−3u+−9+9u+6

=(−3u+9u)+(−9+6)

=6u+−3

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
