Answer:

Step-by-step explanation:

The area of a rectangle is lw or length * width.

We can add the parts to make up the whole of each side.

Thus, for the entire width, we have 4x+3 and for the entire length we have 8 + 5x.

To solve for area in terms of x, we just multiply our width and length, which gives us:

$(4x+3)(8+5x)\\32x+20x^2+24+15x\\20x^2+47x+24$

Answer: OPTION C

Step-by-step explanation:

Complete the square:

Having the equation in the form $ax^2+bx=c$ , you need to add $(\frac{b}{2})^2$ to both sides of the equation:

You can identify that "b" in the equation $x^2+6x=5$ is:

$b=6$

Then:

$(\frac{6}{2})^2=3^2$

Add this to both sides:

$x^2+6x+3^2=5+3^2$

Rewriting, you get:

$(x+3)^2=14$

Solve for "x":

$x+3=\±\sqrt{14}\\\\x+3=\±\sqrt{14}\\\\x=\±\sqrt{14}-3$

Then, the solutions are:

$x=-3+\sqrt{14}\ or\ x=-3-\sqrt{14}$

A man bought a bicycle for $400 and sold it at a loss of 35%. How much money did he lose?

DedPeter [7]

If he bought the bike for $400 and lost 35% of his profit, you would divide 35 by 100. Next, you would multiply that number (0.35) by 400. When you do that, you get an answer of $140. In conclusion, if he bought the bike for $400 and sold it at a loss of 35%, he would lose $140 from that $400.

Additionally, if you wanted to know what exactly he sold it for, you would simply subtract 140 from 400. Which would be $260.

So, he bought the bike for $400, but when he resold it, he lost $140 of that pay. Basically, he resold the bike for $260.

I hope this helps! :) Let me know if you need help with anything else!
