<p>@levinel that is the correct way to do it
i forgot about that geometric principle</p>

<p>Angle D is OBVIOUSLY different than Angle C</p>

103

<p>could 29 work for the 63 left problem?</p>

104

<p>How do you guys think the curve will be on the Math section?
I think I got 0 questions incorrect, but still, it seemed significantly easier than other practice ones i had taken.
The reading, however, was extremely more difficult than average imo.</p>

105

<p>@skorpius7
you dont need angle C to solve the problem
you can use the intersecting parallel lines rule from geometry</p>

106

<p>can you stop posting incorrect answers skorpius? the answer was 105, it had nothing to do with it being a trapezoid. it was just two lines cut by a transversal and you were given an alternate interior angle and asked to find the other.
also the triangle WAS equilateral. each side had to be 1/2 the sum of the other two. that doesn’t work for your 2,4, 6 triangle</p>

<p>my other answers
40 for the cube
4 for n and k
10 percent for approx.
the always positive parabola (dont remember question)
19 for the last grid in
180 for x on grid in
2:1 ratio
10/3 for the slope problem grid in</p>

107

<p>math for me was medium. I’m kind of scr*wed think I have minus 5 2 omit. I want 650+</p>

108

<p>What was the trapezoid question? I really don’t remember anything about a trapezoid.</p>

<p>Was the one with the function flipped over the x axis (#19 I think) -3?</p>

109

<p>Skorpius I’m not sure what problem you are going over in your head but the answer is definitely 105.</p>

110

<p>Same answers as EconHopeful94, except I had 20 for last grid-in, but they both work :)</p>

111

<p>@econhopeful
99% sure those answers you have are all correct</p>

112

<p>what about the parabola questions? what was the actual question</p>

113

<p>awww crap i guess you guys are right… :confused: sorry </p>

<p>-3 so far -.-</p>

114

<p>@levinel
20 works as well</p>

115

<p>@defianced t=x-b b is a constant
What is the graph of y defined as y= (-t)^2</p>

116

<p>pen question: 1.4?</p>

<p>and max quadratic was the first answer?</p>

<p>Good at math: the graph was the positive quadratic one</p>

117

<p>i got 1.6 for pen question</p>

<p>am i right?</p>

118

<p>i think the question was t= x-b. where b is a constant. what could be the graph of (-t) squared? since it was squared, the answer had to be positive. since the answers increased exponentially not linearly, it was a parabola.
@kevinsupreme if all my answers are correct i might have gotten an 800 :)</p>

119

<p>@ GoodAtMath, i believe it was the one that was curving upward on the X-axis, a little bit shifted to the right. Anyone agree?</p>

120

<p>the quadratic answer was the up facing parabola</p>
