Answer:
A. x² -4
B. 2x² +8
Step-by-step explanation:
The area of a square is the square of the side lengths. That means the area of each large square is x², since it has a side length of x.
__
A. The area of 4 small squares is subtracted from the area of the large square to find the shaded area:
x² -4×1² = x² -4 . . . area of Figure A
__
B. The area of two small squares is added to the area of two large squares to find the shaded area:
2x² +2×2² = 2x² +8 . . . area of Figure B
I believe it will be B. y = 15,000 - 950 x
So after a year it will be 15,000 - 950 = 14,050
Distance swam in 5 minutes = 85.4 yards
Since, 1 min = 60 seconds and 1 yard = 0.91 meter
5 minutes = 
seconds
85.4 yards = 
meters
So, Distance swam in 300 seconds = 77.7 meters
Now, we will use unitary method to determine the distance swam in 70 seconds.
Distance swam in 1 second = 
= 0.26 meter
So, Distance swam in 70 seconds = 
= 18.2 meters
Therefore, the swimmer took 70 seconds to cover the distance of 18.2 meters.
Answer:
B
Step-by-step explanation:
First, subtract 3 by the numbers
-8 > 4x > 4
Remember to flip the inequality signs
Second, divide all the numbers by 4
-2 < x < 1
Flip the inequality signs again
-2 > x > 1
I am not very experienced with these problems so I might be wrong.
