Answer: The value is 18.
Step-by-step explanation:
Since we already know what <em>p, q, and r</em> equal, we can use what we know and plug in the numbers:
p=7, q=5, and r=3,
p2=7*2=14
q2=5*2=10
r2=3*2=6
In conclusion, 14+10-6=18
The value of p2+q2-r2 is 18.
Step-by-step explanation:
go to school do math then you'll figure out
Answer:
74
Step-by-step explanation:
first subtract the 78 to 82
then you will get 4 then subtract 78 by 4
and u get 74
If the problem was written x + 4x. We would know to add like the coefficients together and get 5x same thing with the radicals.
Answer: x=12
First, you do 8 squared = 4(4+x)
Then, you distribute and becomes a two-step equation.
64=16+4x.
So x=12.
