<li>A^3 x B^2 = 432, what is the value of AB?</li>
</ol>
<p>For number 2, just use trial and error with numbers that aren’t too large (because cubes get big very quickly). A=3, B=4 works.</p>
<p>I can’t read the numbers in the picture for number 1. If you can tell me what they are, I’ll give a solution.</p>
<p>Which of the following represents the area of the five-sided figure above?</p>
<p>A) 1/2 X^2 + 3/2 Y
B) 1/2 X^2 + 3Y
C) 3Y - 1/2 (X-3)
D) 3Y + 1/2 (X-3)
E) 3Y + 1/2 (X-3)^2</p>
<p>The numbers on the figure are: “X” on the far left side of the figure, “3” on the far right side of the figure, “Y” is the length of the bottom side of the figure. The side drawn that cuts the rectangle is my drawing, not part of the problem, therefore the figure all in all is five sides if you count them. And finally, the measure of the angle at the top left is 45 degrees.</p>
<p>Sorry for the ****ty picture. And thanks for number 2!</p>
<p>the image’s answer is D, 3y + .5(x-3)^2, and not A. This is becasue you can find the length of the entire bottom strip with y<em>3. the remaining vertical figures for the triangle to the left would be x-3 (because you cannot account for an area twice, and because it is a right triangle, you know that the horozontal figure will be x-3 as well. the area of a triangle is .5l</em>w, so you add teh values together to get 3y + .5(x-3)^2</p>
<p>did i help at all? let me know if i lost you somewhere and i can clarify on that. im in calc C right now so you can trust my trig haha</p>
<p>^No sorry, the answer is E.</p>
<p>I think you misinterpreted the length of the bottom side. It is not x and y. It is only y.</p>
<p>Side note to everyone: The X written on the bottom side of the figure is not part of the problem, nor is the short line that cuts the rectangle in half either.</p>
<p>sorry, i meant E. i said taht it would be 3y + .5(x-3)^2 i just put the wrong letter. my steps are still applicable just erad it instead of skipping to my final answer</p>
<p>Yeah, I understood the steps, but the final answer confused me. I understand the logic now though, thanks!</p>
<p>no problem, enjoy your lots of wanking, sir <em>bows</em></p>
