If p=7,q=5,r=3 find value of p2+q2-r2
2 answers:
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.
Answer:
Just simply change the variables with their values
7 x 2 + 5 x 2 - 3 x 2
14 + 10 - 6
24 - 6 = 18
18 is the answer
