Order the side lengths , , , , and from least to greatest.
diamong [38]

Answer:

1. FH, 2. GH,  3.IH  4. GI,  5. FG

Step-by-step explanation:

According to a certain geometric theorem, the smallest angle is always opposite to the smallest side of a triangle. Likewise, the largest angle is always opposite to the largest side. Using this theorem we can properly order the angles and sides.

Additionally, the interior degrees of a triangle will always be 180, and the interior of this quadrilateral is 360 degrees. Using this we can determine the missing angles.

180 - 75 - 55 = 50 (first missing angle)

180 - 59 - 63 = 58 (second missing angle)

The smallest angle would be 50 degrees and the largest 75.

The second smallest is 55 degrees, the third smallest is 58 degrees, the fourth smallest is 59 degrees, and the fifth is 63 degrees.

Now, one thing that seems a bit confusing is the fact that GH is opposite to 2 different angles, so how do we know WHICH angle to use to find its length. From what I understand, we should be able to find the average of the two angles across from this side to see what its place would be in terms of length.

63 + 50 = 56.5

This would make side  GH larger than FH but less than HI

This is how I would solve the problem, and I think this is the correct order. Please let me know whether it turns out right.

Distributive property combined like term.... 3(x+2)+14-7x
GaryK [48]
First you would distribute the 3. So it would be (3x+6)+14+7x. Since you can’t do anything inside the parentheses, you drop them. Then you’d combine like terms. 3x+7x is 10x, and 14+6 is 20. That would get you your answer, 10x+20

Can someone help me. <br><br><br> Which equation represents the data in the table?
nydimaria [60]

Answer:

D) t=4d+5

Step-by-step explanation:

If d=1,

t=4\times 1+5\\t=9

If d=2,

t=4\times2+5\\=8+5\\=13

If d=4,

t=4\times4+5\\=16+5\\=21

Therefore,

t=4d+5

true or false. for a continuous function, of f(2) is negative and f(3) is positive, then there must be a zero between x=2 and x=
Rashid [163]

It's true. In general, if a function is continuous, and you have

f(x_1)=y_1,\quad f(x_2)=y_2

then f(x) spans all the possible values between y_1 and y_2 in the interval [x_1,x_2]

So, in particular, if you have

f(2) = y_2 < 0,\quad f(3) = y_3 > 0

you can conclude that in the interval [2,3], f(x) span all the values between y_2 and y_3, which include 0 because y_2 is negative and y_3 is negative.
