<p>The sides of the triangle are (3,4,6). </p>
<p>The two triangles are congruent because "each angle of /\ABC has... has the same measure as an angle in /\XYZ." The length of one side of /\XYZ is 24. The question is "what is one possible perimeter of /\XYZ?"</p>
<p>If 24 corresponds to 3 - the ratio = 8.
8(4) = 32
8(6) = 48
32 + 48 + 24 = 104</p>
<p>If 24 corresponds to 4 - the ratio = 6.
6(3) = 18
6(6) = 36
18 + 36 + 24 = 78</p>
<p>If 24 corresponds to 6 - the ratio = 4.
4(3) = 12.
4(4) = 16.
12 + 16 + 24 = 52</p>
<p>The answer is one of the following: 52 78 104</p>
<p>spirited away.. u gav me the answer for pg 411#11.. i wanted pg 411#13..
hope u can help me out..
thanks anyway..</p>
<p>39 views n just one reply.. surely somebody must know how to solve those questions..</p>

<p>The figure above shows the graph of y = g(x)
If the function h is defined by h(x) = g(2x) +2, what is the value of h(1)</p>
<p>if you plug in 1, h(1) = g(2) +2
so u find the spot where x = 2 on the g(x) graph, and u find that it corresponds to a 1 y value. now because it says g(2) + 2, u add 2, and 1+2 = 3.</p>

the answer is (D) because the hypotenuse created by XD is the greatest distance in the rectangle. if the hypotenuse is bigger, it cuts <XDY into a smaller piece. look at <XBY, because it has a small hypotenuse, the angle is pretty big. so, big hypotenuse = small <XDY</p>

u have to find the value of a where h(a) = 0; y is only 0 slightly to the left and far off to the right. if you make check marks of equal size as the 1 on the x-axis, the far-right intersection is at 5, not 4. the left, however, is at -1, which is answer choice (A)</p>

What is the value of AB?</p>
<p>in dealing with 3-d figures, there is an advanced form of the pythagorean thrm:
d^2 = a^2 + b^2 + c^2
where d is the hypotenuse, a and b are the "x" and "y" and c wud be considered the "z" or the depth.</p>
<p>from A to the corner = 1
from corner to corner = 2
and from corner up to B = 1
d^2 = 1^2 + 2^2 + 1^2
d^2 = 1+4+1
d^2 = 6
d = root 6
(D)</p>
<p>pg 684, #16</p>
<p>let X~ = x^2 - x
if a~ = (a-2)~, what is the value of a?
first note that the symbol ~ and the oval in the book only means that an operation is being defined; it is not an item that should be familiar or recognizable, u must only understand how it is used
(aslo note that im using "~" instead of the oval surrounding the variables in the book)</p>
<p>start w/ a~
a~ = a^2 - a</p>
<p>then w/ (a-2)~
(a-2)~ = (a-2)^2 -(a-2), simplify
(a^2 - 4a + 4) -a+2
a^2 -5a + 6</p>
<p>set the two equal to each other:</p>
<p>a~ = (a-2)~
a^2 - a= a^2 -5a + 6
-a = -5a +6
4a = 6
a = 6/4 or 3/2
(C)
enjoy</p>
<p>Ooops........... :o</p>
