The area (A) of a square is determined by using the formula, A = s² where s is the measure of each side. Given s = 3 ft, the area of the square is
A = (3 ft)² = 9 ft²
Doubling the sides makes them 6 ft. The new area is, A = (6 ft)² = 36 ft². The new area is not double of the previous area but four times. The new area (An)
An = (2s) ² = 4s² = 4A
Answer:
The answer would be 20 mi
Step-by-step explanation:
a^2+b^2=c^2
a^2=144
b^2=256
C^2=400
Then you find the square root of ABC to find that C is 20
Answer:
![f=-\frac{5}{3}](https://tex.z-dn.net/?f=f%3D-%5Cfrac%7B5%7D%7B3%7D)
Step-by-step explanation:
![-\frac{3}{4}f=\frac{5}{4}](https://tex.z-dn.net/?f=-%5Cfrac%7B3%7D%7B4%7Df%3D%5Cfrac%7B5%7D%7B4%7D)
![(4)-\frac{3}{4}f=(4)\frac{5}{4}](https://tex.z-dn.net/?f=%284%29-%5Cfrac%7B3%7D%7B4%7Df%3D%284%29%5Cfrac%7B5%7D%7B4%7D)
![-3f=5](https://tex.z-dn.net/?f=-3f%3D5)
![\frac{-3f}{-3}=\frac{5}{-3}](https://tex.z-dn.net/?f=%5Cfrac%7B-3f%7D%7B-3%7D%3D%5Cfrac%7B5%7D%7B-3%7D)
![f=-\frac{5}{3}](https://tex.z-dn.net/?f=f%3D-%5Cfrac%7B5%7D%7B3%7D)
Answer:

Step-by-step explanation:
Answer:
6
Step-by-step explanation:
(-4+2) (4- -4)
-Add your invisible 1
1(-4+2)1(4- -4)
-This removes the parentheses.
-Combine the 2 negative signs in the second set of parentheses.(Its now a positive or plus sign.)
-4+2+4+4
Combine like terms.
