Step-by-step explanation:
This is a cube
Formula surface area of a cube = s2 × 6
Where s is one side
Square of 8 = 64
64 × 6 = 384
Yeah you answered it correctly
2(4+2x)25x+5 = 300x + 5
2(4+2)•25x+5
2(4+2)•25x=300x
= 300x + 5
X^2+y^2-8x+4y+4=0 can be written as (<span>x- 4)² + (y+2)²-16-4+4=0, or
</span> (<span>x- 4)² + (y+2)²=16, this is not a an equation of parabola, it is a circle's
</span>its center is (4, -2) and its radius r=4
