Answer:
1. 24
2. B
Step-by-step explanation:
1. 7^2+x^2=25^2
49+x^2=625
x^2=576
x=24
2. 15^2+36^2=39^2
225 + 1296 = 1521
Answer:
Equation is
and when y=2 and z=4, x will be 4.
Step-by-step explanation:
Given:
x varies jointly with y and z.
It also means x is directly proportional to y and z.

From above values we can compute the equation as.

Hence the Equation is 
Now y=2 and z=4 we get.

Hence when y=2 and z=4, x will be 4.
7% = 0.07
0.07/4 = 0.0175
The answer is 0.0175
I believe the answer is x= -1.583. the 3 is repeating
