4(c - 3)=8 What is the value of the C? i really need help, i will mark brainliest

c = 5

Step-by-step explanation:

4 (c - 3) = 8

4c - 12 = 8

     +12  +12

4c = 20

c = 5    Check:

4 (5 - 3) = 8

20 - 12 = 8, the answer is correct

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.

the answer is 1030 it's very simple math.
