189 because 20.7 rounds to 21 and 9.18 rounds to 9
21 * 9 = 189
The answer would be $112.
explanation:
40%——> .40
280 x .40 = 112
Simplify the following:
(8 x^2)^3
Multiply each exponent in 8 x^2 by 3:
8^3 x^(3×2)
3×2 = 6:
8^3 x^6
8^3 = 8×8^2:
8×8^2 x^6
8^2 = 64:
8×64 x^6
8×64 = 512:
Answer: 512 x^6
Hey, there!!
Given that:
y = 3x.........(i)

Putting the value of y in equation (ii)

=0


Therefore,
Either Or
(x+4)=0 (x-4)=0
x= -4 x= 4
so, x= (+ -)4
And if you wanna get value of y, just keep value of x in equation (i).
y= 3x
y= (3×4) or (3×-4)
y= 12 or -12
{As it is the quadratic equation it has two values. }
