How many solutions does this equation have?

4 (z - 5) + 2 = 4z - 18

a. 0
b. 1
c. infinitely many

C. Infinitely many

Step-by-step explanation:

You can replace z with any number, and there are an infinite amount of numbers.

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
