Answer:
The area of the new reduced parallelogram after dilation is 8 cm^2
Step-by-step explanation:
Mathematically, the area of a parallelogram = b * h
before dilation, area of the parallelogram = 8 * 4 = 32 cm^2
After dilation by a factor of 1/2, the base of the parallelogram becomes 1/2 * 8 = 4cm while the height becomes 1/2 * 4 = 2cm
Thus, the area of the dilated parallelogram is 4 * 2 = 8 cm^2
Answer:
A negative number that is 12 less than its square is -3.
Step-by-step explanation:
This is because (-3)² = 9 and 9 - 12 = -3.
You can get this answer by testing different number until one works in the given situation. This is done by testing numbers by squaring them and then subtracting 12 to see if it equals the original number.
