Answer:

20 + -9 + 8 + -7

Step-by-step explanation:

A epression DOES NOT have a equal sign,  =

20-9+8-7 = 12

20 + -9 + 8 + -7

to check -->

20 +-9 + 8 + -7

20 + -9 = 20 - 9 = 11

11 + 8 = 19

19 + -7 = 19 - 7 = 12

So therefor it would be

20 + -9 + 8 + -7

Tyree plans to use SSS to prove two triangles made from a sheet of paper are the same. Which diagram best supports his plan to u
Ilya [14]

Answer:

Bottom left choice

Step-by-step explanation:

SSS congruence is side-side-side congruence, which is a method to prove triangles congruent by all three sides of the triangle being congruent. The other choices all involve congruent angles. Therefore, the bottom left choice is the best answer.

Also, notice that the bottom left choice shows which side is congruent to which. All three sides of one of the triangles are shown to be congruent with the corresponding side to the other triangle, therefore, congruent by SSS.

I hope this helps! :)

1-5. Evaluate each absolute value expression. Can you help me with this and if you can explain it to me thanks you
mihalych1998 [28]

Well when it comes to absolute value remember that whatever number is inside the two straight lines will always come out as a positive.

a) [54] would still be 54

b)-[-7 3/5] so first you get the absolute value which comes out to 7 3/5 but because there is a negative sign out side of the two parallel lines, the answer would be -7 3/5

c)[3]-[-1] the absolute value of 3 is 3 and the absolute value of -1 is 1. So the expression would be 3-1 which comes out to 2

d)[2.2-5.13] 2.2-5.13 would equal -2.93 but since it is in the absolute value, the answer would come out as 2.93

Hope this helps!
