What are the variables in this expression? f+2g+h/4-7.1 f and g only 2 g and h only 3 f, g, and mc014-2.jpg only 4 f, g, and h only

4. only.

Step-by-step explanation:

We have been given an expression . We are asked to find the variables in the given expression.

We know that variable is a symbol or letter that represents an unknown value in a mathematical expression.

We can see that in our given expression are unknown, therefore, these are variables for our given expression.

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this
