2D-a^2=2
2(a√2) -a^2=2
a^2-2√2*a+2=0
2a= 2√2 + √(8-4*2) = 2√2
hence, perimeter = 4a = 2*2a=2*2√2 = 4√2
3/(5x) + x = 3/(5x) + x/1 * (5x)/(5x)
= 3/(5x) + 5x²/5x
= (3+5x²) / 5x
The formula for the volume of a cube whose sides are s inches longs is volume = s^3 cu. in which is A on the choice you provided. We all know that 3 is for cube and the s^3 in the formula saying that s^3 is s cube, we will just include the inches and the cube o the formula which will be the choice A.
