Step-by-step explanation:
Dagney reads at 40 pages an hour, or .75 pages a minute.
it would take 4.5 hours to read the novel
678 to the nearest hundred the answer is 700
"total" means "sum" more or less, so the total of m and 10 is m+10
The square of this is (m+10)^2
----------------------
If you want to expand this out, then you would get
(m+10)^2 = (m+10)(m+10)
(m+10)^2 = A(m+10) ... let A = m+10
(m+10)^2 = A*m + A*10
(m+10)^2 = m(A) + 10(A)
(m+10)^2 = m(m+10) + 10(m+10) .... plug in A = m+10
(m+10)^2 = m^2+10m+10m+100
(m+10)^2 = m^2+20m+100
