To simplify that expression, you need to combine line terms so in order for you to go that, you would need to combine -9n, +4n, and -10n
You would get: 16m-15n

C. Exactly one unique triangle exists with the given side lengths.
<u>Step-by-step explanation:</u>
A triangle consists of three sides, depending on the measurement of the sides, naming of the triangles can be varied.
If all the three sides are equal in length, it is said to be an equilateral triangle. Only one triangle can be formed using the measures of 7 in, 7 in, 7 in, that is all the three sides are same in measurement of 7 inches.
So, Exactly one unique triangle can be produced with the given side lengths.
Given :
The probability of someone having a reaction to a medication is 0.025 .
To Find :
The probability of two out of tree people having a reaction.
Solution :
Let, P is the probability of two out of tree people having a reaction.
So, P = ( first had reaction ) × ( second had reaction ) × ( third do not had reaction )
P = 0.025 × 0.025 × ( 1 - 0.025 )
P = 0.00061
Hence, this is the required solution.
Answer:
Question 1: B = 0
Question 2: 23/2 or 11-1/2
Question 3: 663/6 or 110-3/6
Step-by-step explanation:
Question 1:
(-5²)+(9+4²)=5B
-25+9+16=5B
5B=-0
B=0/5=0
Question 2:
2-7/8×2-6/9×1-1/2
=23/8×24/9×3/2
=23/2
=11-1/2
Question3:
3-1/4×6-2/3×5-1/10
=13/4×20/3×51/10
=663/6
=110-3/6
