Answer:

$A = 2x^2 + x - 28$

Step-by-step explanation:

The formula for the area of a rectangle is <em>A = lw</em>, where w=width and l=length.

Substitute the known values into this equation, and then it can be simplified.

$A=(2x-7)(x+4)$

Now we can expand the polynomial using FOIL (multiply the first, outer, inner, then last terms).

$A = 2x^2 + 8x -7x -28$

Add like terms and put in standard form.

$A = 2x^2 + x - 28$

Line segment MN is graphed in the first and second quadrants of a coordinate plane. The segment is translated 2 units up, then r

Answer:

Step-by-step explanation:

Since the line segment is only being translated and reflected it would still maintain its length. This is pretty much the only characteristic that would remain the same as te original line segment. It would not maintain the same x-axis positions for both endpoints of the line segment. This is because when it is translated 2 units up it is only moving on the y-axis and not the x-axis. But when it is reflected over the y-axis the endpoints flip and become the opposite values.

HELP!!!!!

frosja888 [35]

Answer:

I think it is 350(1.2)^t because you take the starting amount (350) and then multiple it by the growth rate (which is 20%, but when added to 100 and the put into a decimal is 1.2) raised by the number of hours (t).

I hope this helps.
