Answer:
a= 2/b-c
Step-by-step explanation:
We want isolate for a or to be itself
ab-ac=2
factor out a
a (b-c)=2
Now bring b-c to the other side
a (b-c)/(b-c)=2/b-c
The b-c cancel each other out
a= 2/(b-c)

Answer: -6, 7, -8</h3>
Start with the sequence {1, 2, 3, 4, 5, 6, 7, 8, ...}
Then change the sign of every other term so you'll have the first term positive, the second term negative, and so on.
That updates to {1, -2, 3, -4, 5, -6, 7, -8, ...}
Every odd term (1,3,5,..) is positive while every even term (-2,-4,-6) is negative.
The answer is C. 50 in, 48 in, 14 in
In a right triangle, a² + b² = c², where c is the longest side (hypotenuse), a and b are the other two sides.
14² + 48² = 196 + 2304 = 2500
50² = 2500
Basically add up the given side lengths and subtract that from 180 for the triangles
Answer:

Step-by-step explanation:
