To simplify the expression (4.8b-0.6bc-1.5bd) by (0.3b), we will distribute the 0.3b to each term in the expression:
(4.8b)(0.3b) - (0.6bc)(0.3b) - (1.5bd)(0.3b)
Now we can simplify each term individually:
1.4.8b)(0.3b) = 1.44b^2
Therefore, the simplified expression is:
1.44b^2 - 0.18bc^2 - 0.45bd^2
To simplify the expression (4.8b-0.6bc-1.5bd) by (0.3b), we will distribute the 0.3b to each term in the expression:
(4.8b)(0.3b) - (0.6bc)(0.3b) - (1.5bd)(0.3b)
Now we can simplify each term individually:
1.4.8b)(0.3b) = 1.44b^2
(0.6bc)(0.3b) = 0.18bc^2(1.5bd)(0.3b) = 0.45bd^2Therefore, the simplified expression is:
1.44b^2 - 0.18bc^2 - 0.45bd^2
