If both the hoses are on the same time then the height of the water in the pool is given by the expression 15g^2 + 5g - 6
Step-by-step explanation:
(7g^2 + 3g - 4) + (8g^2 + 2g - 2)
= (7g^2 + 8g^2) + ( 3g + 2g) + (-4 -2)
with the help of distribution law,
= (7 +8)g^2 + (3 + 2)g - (4 + 2)
= 15g^2 + 5g - 6
Therefore if both the hoses are on the same time then the height of the water in the pool is given by the expression 15g^2 + 5g - 6
