Answer:

it is probably like around but im not sure if this is the answer but i think its like 50-60

Step-by-step explanation:

i said this because if it was at 80, and  there was a discount of 20%, it will probably go down in some dollars, like 70. and there was a 40% discount and that can probably make it go down to like my answer which was 50-60, but im not really sure if it is the answer

A square has an area of 16x^2 square inches. If the sides of the square were to increase by 2 units, what is the new area of the
kykrilka [37]

Answer:

16x² + 64x + 64

Step-by-step explanation:

Given

A = 16x²

Increasing the sides by 2, substitute x = x + 2 into A

A = 16(x + 2)² ← expand factor using FOIL

   = 16(x² + 4x + 4 ) ← distribute

   = 16x² + 64x + 64

what is an equation of the line that is perpendicular to line y= -1/2x -2 and passes through the point (0,-4)?
LiRa [457]

Answer:

y = 2x -4

Step-by-step explanation:

y = -\frac{1}{2}x - 2\ \ \ \ \ \ (0, -4)

To find the perpendicular equation of a line,

You need the product of their gradients to be -1

-\frac{1}{2} \times ? = -1

Divide both sides by -\frac{1}{2}

? = 2

The gradient of the perpendicular line is 2

Straight line formula is in the form y = mx + c

y = 2x + c

We're nearly there, we just need to find out c.

Luckily, we're given a point (0, -4)

(x, y) = (0, -4)

y = 2x + c

-4 = 2(0) + c\\-4 = 0 + c\\c = -4

We then end up with...

y = 2x -4
