P=4πlr²
r²=P/4πl
r=√(P/4πl)= 1/2*(√(P/πl)
Answer is A
Solving is :
X=2
Y=1
Step by step
(2x-3) + 5 = 3x
2x+2=3x
X=2
Substitute x by 2
Y=1
Answer:
A
Step-by-step explanation:
=16x²-25
=(4x)²-(5)²
Using formula a²-b²=(a+b)(a-b)
=(4x+5)(4x-5)
Answer:
Answer in simplified form is - 10 1/2 .
Step-by-step explanation:
We have given,
(5 1/4) ÷ (- 2 1/2)
This can be simplified as :
(5 1/4) ÷ ( -2 1/2)
Since 5 1/4 = 21/4 and -2 1/ 2 = -5/2
So we can write,
(5 1/4) ÷ ( -2 1/2) = 21/4 ÷ ( - 5/2)
or (21/4) / (-5/2)
or ( 21/4) * (-2/5)
or -42/20
or -21/10
or - 10 1/2 , this is the answer
Hence we get answer in simplified form as -10 1/2
