Your answer would be sliding. hope that helped
It would be $1,800
You would use the distributive property to do 18x5 and then 20x5 and then add those to get 1,800
Answer:
-18
Remember PEMDAS.
Step-by-step explanation:
In order to prove these triangles congruent by SAS, AB and DE must be congruent. Thus, C is your answer.
Have an awesome day! :)
Okay. In my opinion, all the class has to do is simplify the expressions and compare. But they want to substitute instead.
Well then.
First, let's notice that these are linear expressions, meaning that if they are equivalent then all their values match up.
Number 1 is not a good one. Just because they're both positive doesn't mean anything; they have to be <em>the same.</em>
This also eliminates 3.
Number 2 is a good one, but it's not as reliable. If, for instance, the two expressions are <em>not </em>equivalent and you get lucky enough to pick that one value they intersect at (or have in common), then you'd be wrong when you say they are equivalent.
Number 4 makes the most sense because if both expressions are equivalent, then every value matches up. If not, then only one will. So having two values to substitute will most definitely answer the class question.
Hope this helps, let me know if I messed up! ;)
