Find all excluded values for the expression. That is, find all values of for which the expression is undefined.
3v

2v+10

If there is more than one value, separate them with commas.

-5

Step-by-step explanation:

For an expression to be undefined, the denominator must be equal to 0

Therefore, we must equate the denominator in the expression to 0

2v + 10 = 0

2v = 0 - 10

2v = -10

v = -10/2

v = -5

So in order for the expression to be undefined, v must be equal to -5

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

probability for j is 1/4

while

a is 1/6
