Answer:
12 roses
Step-by-step explanation:
$52 to spend at the florist
a vase for $11.75
roses for $3.50 each
Calculating how much left after buying the vase:
$52 - $11.75 = $40.25
To Know the possible numbers of roses Erin can buy, divide:
$40.25 ÷$3.50 = 11,75, roundind 12 roses
"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
Answer:
The height is 20 meters
Step-by-step explanation:
First set up the equation (Area)80=bh/2 then set up another equation, (height) h=4+2b (base). After this you can substitute h in the equation to end up with 80=(b(2b+4))/2 simplify it to get 80=b^2+2b then solve. The base is 8 meters, plug into the formula that we made before and you find the height is 20 meters.
