38-39. a right triangle has 2 equal sides that measure 12 inches is cut from plate. it has a 3" square cut out of
the center. what is the total area left of the triangle?

63  inch²

Step-by-step explanation:

area of triangle: (12 x 12) / 2 = 72

area of square cut out: 3 x 3 = 9

area left: 72 - 9 = 63

its 69.420

step-by-step explanation:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
