Answer:
0.001189 x 10^7
Step-by-step explanation:
4.1 x 10^7 gallons of water
2,900 gallons of water = 2.9 x 10^3
Balance the 10th power with the first one.
2,900 = 0.00029 x 10^7
Multiply only the decimal number...
4.1 x 0.00029 = 0.001189
The answer is...
0.001189 x 10^7
 
        
             
        
        
        
Area of a rectangle  =  length x height
Area = 135
Height = X
Lenght = x +6
135 = x * x+6
Simplify:
135 = x^2 +6x
Subtract 135 from both sides:
x^2 + 6x - 135 = 0
Solve:
2 numbers when added need to equal 6 and when multiplied equal -135
x = 9 and x = -15
The height can't be a negative number so the height is 9
Length =  9 +6 = 15
Height = 9cm, Length = 15 cm
