The vertices of ΔRST are R(–1,–1), S(–1,11) and T(4,11). Which could be the side lengths of a triangle that is similar but not c
Step2247 [10]
The side lengths could be 10, 24 and 26 units.

We must first find the side lengths.  We use the distance formula to do this.

For RT:
d=\sqrt{(11--1)^2+(-1--1)^2}&#10;\\=\sqrt{(11+1)^2+(-1+1)^2}&#10;\\=\sqrt{12^2+0^2}=\sqrt{144}=12

For ST:
d=\sqrt{(11-11)^2+(4--1)^2}&#10;\\=\sqrt{0^2+(4+1)^2}=\sqrt{5^2}=\sqrt{25}=5

For TR:
d=\sqrt{(11--1)^2+(4--1)^2}&#10;\\=\sqrt{(11+1)^2+(4+1)^2}=\sqrt{12^2+5^2}=\sqrt{144+25}=\sqrt{169}=13

Our side lengths, from least to greatest, are 5, 12 and 13.

To be similar but not congruent, the side lengths must have the same ratio between corresponding sides but not be the same length.  10, 24 and 26 are all 2x the original side lengths, so this works.

It says circle the terms,then simplify each expression to 5•3+4
RoseWind [281]
So first you have to do PEMDAS (Parenthesis, Exponent, Multiply, Divide, Add, Subtract). Now, when you do PEMDAS, you need to go from left to right in the order I just described to you.

So in this situation, first multiply 5 times 3 to get 15. Next is addition. 15+4=19.

PS sorry for taking so long.
