Answer: 
, where x= width of the rectangle ( in inches).
Step-by-step explanation:
Let x= width of the rectangle ( in inches).
Then its length = 2x-7 ( in inches).
Area of rectangle = Length × width
= (2x-7) × (x)
= 2x × x -7 ×x
= 2x²-7x
The area of the rectangle is 72 square inches.
Hence, the equation that represents the given situation :
Assuming that the pool was drained at a constant rate, the speed at which it was drained can be expressed as a function of time. In this case, the pool level will be expressed in feet per hour.
The time changed by 4 hours (6-2), and the level of the pool changed by -8 feet (2-10). Diving the feet by the hours to get the rate of decreasing depth, we find that the rate equals -2 feet/hour.
Answer:
m=76
Step-by-step explanation:
Answer:
m=30°
n=35°
Step-by-step explanation:
So the right triangle's angles are 90 and 70 so m=30° because sum of angles in a triangle=180°
since the triangle with 110 degrees is congruent, that means the other blank angle is also N.
so if the sum of angles in a triangle is 180 degrees,
110+2n=180
2n=180-110
2n=70
n=35
