Step-by-step explanation:
5: x= 15.3
6: x= 11.7
7: x= 18.6
8:x= 31.7
9: x= 47.0
10:x= 25.0
when two numbers have the same variable, we can add and subtract just like normal numbers.
12x + 8x = 20x - 3x = 17x
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 answer is going to be 6.0
Step-by-step explanation:
