Michaela wrote the following. if p + 9 = 25 and p = q, then q + 9 = 25. which property did michaela show?
a) symmetric property of equality
b) multiplication property of equality
c) substitution property of equality
d) reflexive property of equality

The correct option is C.

Step-by-step explanation:

The given equation is

                 .... (1)

and

                       ...(2)

According to the  substitution property of equality, if we have two equation then we can substitute the values form one equation to another equation.

Equation 2 represent that the value p and q are equal.

Using substitution property of equality the first equation can be written as

Therefore Michaela use substitution property of equality and option C is correct.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse
