Answer:
9a, 18x, and -2c
Step-by-step explanation:
7+2=9 (keep the variable=a)
8+10=18 (keep the variable=x)
5-6=-1 +8= 7-9=-2 (keep the variable=c)
The area of the shaded region is the square subtract the circle. The radius of the circle is the diameter/2
Area of circle= pi x radius x radius
=3.14 x 5 x 5 = 78.5
Area of the square = side x side
= 10 x 10 = 100
Area of shaded 100 - 78.5 = 21.5
And don’t forget the unit of measurement (meters)
I think 18q-4 is the answer
Area of square is a^2
4^2 = 16
the area is 16 units
The unit rate means we need to find it per one soda can. So, 32/32 is one. We do the same to $3.99. $3.99/32 is about 13 cents.
Unit rate is: 13 cents per soda can
