Answer:
Because we know the height of the mailbox is 4 feet and the length is 6 feet, and we also know that it's located 54 feet from the base of the flagpole, we can use proportions to solve the problem.
= 
Cross-multiply 4 with 54 and 6 with x to result with 216=6x. Divide 6 to both sides to get 36. So, the height of the flagpole would be 36 feet.
Multiply 20 and 12 then divide hope this helps :)
Answer:
A. 10x+18=48
Step-by-step explanation:
She uses x eggs per cake, and she bakes 10 cakes. She has 18 eggs left over. So the product of the 10 cakes and the number of eggs she used for each cake, plus the 18 eggs left over will get you the ending answer of 48.
The answer is b
A^2+b^2=c^2
9^2+12^2=15^2
81+144=225
