First you will divide;
200÷4=50
Then you multiply;
50×9=450
Last you add;
2000+450=2450
Answer:
that should be right
Step-by-step explanation:
but if it is wrong i can walk you threw it.
So,
If you do some simple division, you will find how much each cm costs in each cake.
20cm cake = 67.5 cents/cm
25cm cake = 93.75 cents/cm
Assuming that you cannot order fractions of cakes, the best deal would be to order 5 of the 20cm cakes.
Cost = 13.50 * 5 = $67.50
You will have to pay $67.50 for the cakes if you want the best deal.
Answer:
a) (x+2)^2-2
Step-by-step explanation:
write in form of x^2+2ax+a^2
2a=4
a=2
so
x^2+4x+2^2
we will now convert into the form:
x^2+2ax+a^2=(x+a)^2
substitute the values:
x^2+4x+2^2=(x+2)^2
(x+2)^2-2+2^2
(x+2)^2-2
