Answer: = 2(7 + 3) ^2= 2 * 10^2= 200
Hey there!!
Equation given :
A = h ( a + b ) / 2
Multiply by 2 on both sides
2A = h ( a + b )
Divide by h on both sides
2A / h = a + b
Subtract by b on both sides
2A / h - ( b ) = a
Hence, the option ( a ) is the correct answer
Hope my answer helps!
20+2N=52
now subtract 20 from each side, to get 2N alone
2N=32
now divide each side by 2
N=16
<span> The product of two perfect squares is a perfect square.
Proof of Existence:
Suppose a = 2^2 , b = 3^2 [ We have to show that the product of a and b is a perfect square.] then
c^2 = (a^2) (b^2)
= (2^2) (3^2)
= (4)9
= 36
and 36 is a perfect square of 6. This is to be shown and this completes the proof</span>
6 is 75% of 8. 6/8 can be simplified to 3/4, which is easier to see as 75%.
