The answer is . . . <u><em>m - k</em></u> minutes is the part of the lawn still unmowed.

You know it takes Paul m minutes to mow the entire lawn, and you know that he's mowed for k minutes so far . . .

 . . . the amount of time left is the total less the amount he's mowed so far

m - k  . . . is the time yet to be spent mowing the rest of the yard.

So work =time times rate or W=TR

so T=m-k
W=(m-k)R

if you want just m-k then m-k is the answer

What two numbers multiple to -3468 and adds to 24
Alex777 [14]

Answer:

72.1 and -48.1

Step-by-step explanation:

I set up the equations x + y = 24 and x*y=-3468. Then I substituted for y and used the quadratic formula to come to two numbers rounded to about 72.1 and -48.1. Hope that helps :)

√(25 - 10 √(3) + 3)<br> (not as a decimal)
nikitadnepr [17]

Answer:

\huge\boxed{\sqrt{25-10\sqrt3+3}=5-\sqrt3}

Step-by-step explanation:

\sqrt{25-10\sqrt3+3}=(*)\\\\25=5^2\\3=(\sqrt3)^2\\10\sqrt3=(2)(5)(\sqrt3)\\\\(*)=\sqrt{5^2-(2)(5)(\sqrt3)+(\sqrt3)^2}\\\\\text{use}\ (a-b)^2=a^2-2ab+b^2\\\\=\sqrt{(5-\sqrt3)^2}\\\\\text{use}\ \sqrt{a^2}=|a|\\\\=|5-\sqrt3|=5-\sqrt3\\\\^{\text{because}\ 5>\sqrt3\to5-\sqrt3>0}
