Answer:
25 and 20
Step-by-step explanation:
p²=24²+7² ⇒ p²= 625 ⇒ p=25
q²=p²-15² ⇒ q²=625 - 225 ⇒ q²=400 ⇒ q= 20
Answer:
The answer is B. 7
Step-by-step explanation:
3 + x = 10
3 + 7 = 10
Answer:
27 by 27
Step-by-step explanation:
Let the sides be x and y. The problem is essentially asking:
Given 2(x+y)=108, maximize xy.
We know that x+y=54. By the Arithmetic Mean - Geometric Mean inequality, we can see that 
. Substituting in x+y=54, we get 
, meaning that 
. Equality will only be obtained when x=y (in this case it will generate the maximum for xy), so setting x = y, we can see that x = y = 27. Hence, 27 is the answer you are looking for.
Step-by-step explanation:
wait sorry that was wrong
First you need to make a multiplier for 100-2.1%, to do this you minus the values and divide it by 100:
100-2.1 = 97.9
97.9/100 = 0.979
Then you multiply all the questions by it:
$45 * 0.979 = $44.055
$765 * 0.979 = $748.935
$1300 * 0.979 = $1272.7
Hope this helps! :)
