The perimeter of the triangle shown is represented by the
expression 10x - 1.
The lengths of two sides are given. Which kind of
expression represents the missing length?
exponential
rational
linear
quadratic
3x + 1
5x - 2

Solution:

The perimeter of the triangle shown is represented by the  expression 10x - 1

The lengths of two sides are given: 3x + 1 and 5x - 2

We have to find the length of third side

We know that,

perimeter of the triangle = sum of length of all three sides

10x - 1 = 3x + 1 + 5x - 2 + third side

10x - 1 = 8x - 1 + third side

third side = 10x - 1 - 8x + 1

third side =2x

2x has variable x and its power is 1

Linear expression is an algebraic expression where the power of variable is equals to 1

Thus linear expression represents the missing length

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
