Evaluate the expression described below if the number is 4. The difference between a number squared and the number. A. 0 B. 4 C.
svet-max [94.6K]
What the above statement is saying is:
If the number is 4, find the difference between the square of the number (the number is 4) and the number itself (the number is still 4).

The square of the number is:
The number^2
= 4^2
= 4 × 4
= 16

The number^2 - The number
= 16 - 4
= 12

36 miles. Call <span>Fort Collins point F, Cheyenne, point C, and Laramie point L. We know that angle F=46.5 degrees, angle L=43.6 degrees, and FC=3.2 inches. </span>Use the law of sines, sinF/LC=sinL/FC,  LC=sin46.5*3.2/sin43.6=2.32/0.69=3.36 inches. Since one inch represents 10.6 miles, 3.36 inches is 36 miles, the distance from L to C.
