Answer:
Dimensions of original room = 12 x 12 feet.
Explanation:
Let the size of old square room be a x a.
New dimension = ( a+4 ) x ( a + 6 )
We have area of the new room will be 144 square feet greater than the area of the original room.
So, ( a+4 ) x ( a + 6 ) = a x a + 144
a²+10a+24= a²+144
10a = 120
a = 12 feet.
Dimensions of original room = 12 x 12 feet.
The formula of a slope:
We have the points (-4, -3) and (-3, s) and the slope m = 3. Substitute:
.48x =36 x=36/.48 x=75 So the total distance to kirk's grandmother's house was 75 miles
