which of these is an example of a literal equation?
a. 2x + 7y
b. ax - by = k
c. 4x + 7 = 22
d. 5 + 20 = 5^2

B.

Step-by-step explanation:

We know that,

Literal equation is an equation having atleast two variables which represents the real values.

So, according to the options, we have,

A.

Though it contains two variables, it is not a literal equation as it is just an expression and not an equation.

C.

Since, it contains only one variable and a literal equation needs atleast two variables.

So, it is not a literal equation.

D.

Since, it does not contain any variable and a literal equation needs atleast two variables.

So, it is not a literal equation.

Finally, we see that,

B.

This equation consists of two variables x, y which represents any real value.

Thus, it is a literal equation.

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing
