Hey there,
Each cake recipe would call for

cup of oil.
So if she is going to make 12 cakes, this would include that she
would need to use 12 cups of oil.

would be your answer!
Hope this helps.

So even postive integers are by defention in form 2k where k is a natural number so
let the sum of even integers to n=S
S=2(1+2+3+4+5+6+7+8+......+k-1+k
divide bith sides of equation 1 by 2
0.5S=1+2+3+4+5+...........+k-1+k
S=2(k+(k-1)+..............................+2+1)
divide both sides of equation 2 by 2
0.5S=k+k-1+..............................+2+1)
by adding both we will get
___________________________
S=(k+1)(k)
so the sum will be equal to
S=

so let us test the equation
for the first 3 even number there sums will be
2+4+6=12
by our equation 3^2+3=12
gave us the same answer so our equation is correct
To determine the hypotenuse, use the formula a^2 + b^2 = c^2.
Place 80 as "a" and 39 as "b". Your formula should look like 80^2 + 39^2 = c^2.
Next, plug this into your calculator to get 7921. Then square root 7921.
Answer: 89
