Answer:d
Step-by-step explanation:
What is the product of 3a + 5 and 2a2 + 4a – 2?
6a3 + 22a2 + 14a – 10
6a3 + 22a2 + 26a –10
18a3 + 10a2 + 14a – 10 What is the product of 3a + 5 and 2a2 + 4a – 2?
6a3 + 22a2 + 14a – 10
6a3 + 22a2 + 26a –10
18a3 + 10a2 + 14a – 10
28a3 + 14a – 10
28a3 + 14a – 10
96 - 15.2 = 80.8
80.8 / 10 = 8.08
He was using up 8.08 pounds of sugar daily for his baking, so the answer is the second option.
30÷25=1.2
she reads 1 page in 1.2 seconds

If it is a ratio of 3:5 you are dividing 480 into 8 parts (3+5).
So divide 480 by 8: 480/8 = 60
Then the ratio is (3x60):(5x60) or 180:300
To check it is correct, add up the two parts to see that they come to 480:
180+300 = 480. All good.
Hope this helps
