Answer:
x = 4
Step-by-step explanation:
The measures of all angles in this geometry are 90 degrees.
21x +6 = 90
21x = 84 . . . . . subtract 6
x = 4 . . . . . . . divide by 21
We need to look at factors of 2, which are only 2 and 1... How do we get them to add to -3? Well, they have to be negative.
-2 + -1 = -3
What about the multiplication? A negative × a negative = a positive, so
-2 × -1 = 2
So your answer is
-2 and -1

Percent decrease=(decrease)/(original) converted to percent
change=120 to 52
120-52=68
change or decrease=68
original=120
68/120=0.5666666=56.6666%
about 57%
