Answer:
2.25
Step-by-step explanation:
The question gives us one hint. That side of the square is 1.5"
Because it gives us that, we can use that to find the area. Because it is a square, all of the sides are the same length.
To find the area it is basexheight
So that is why the answer is 2.25 because 1.5x1.5=the area of the square
Answer:
The numbers are 63, 26, & 21
Step-by-step explanation:
110 = 3x + (5 + x) + x
105 = 3x + 2x
105 = 5x
21 = x
Plug it back into the first equation to find your values
-4r-11=4r+21
Move 4r to the other side
Sign changes from +4r to -4r
-4r-4r-11=4r-4r+21
-4r-4r-11=21
-8r-11=21
Move -11 to the other side
Sign changes from -11 to +11
-8r-11+11=21+11
-8r=21+11
-8r=32
Divide both sides by -8
-8r/-8=32/-8
Answer: r=-4
