Answer:
16
Step-by-step explanation:
(2 means squared) (c is the hypotenuse)
a2+b2=c2
a2+ (12×12) = (20×20)
a2+144=400
a2=256
a=16

Answer:
7.5
Step-by-step explanation:
Lets define what we're looking for, the "number", to be equal to x.
number = x
Following the questions hints:
" The sum of twice a number and three times a number"
(2x) + (3x)
is (which means equals to basically)
" triple the quantity of five more than a number"
3(x+5)
We connect all of this to find the number and get:
(2x) + (3x) = 3(x+5)
5x = 3x + 15
5x -3x = 15
2x = 15
x = 15/2
x = 7.5
