answer of this question is -6-3b
Step-by-step explanation:
taking common -3 then 2+b will left so this is also answer of this question
They get easier once you keep doing them, It took me a little while to learn.
Do you have a exact question? I can help you
Answer: after 3 seconds
when the ball hit the ground => - 5t² + 14t + 3 = 0
⇔ (5t + 1)(t - 3) = 0
⇔ t = 3 or t = -1/5
but t is a positive integer => t = 3
so the ball will hit the ground after 3 seconds

Answer:
88:56 = 11:7 pounds.
Step-by-step explanation:
Drop the pound sign. I live in Canada and I can't make that symbol. I'll add something at the end. We just want to divide 144 into a ratio of of 11:7
Step One
Add the two ratios together 11 + 7 = 18
Now set up a ratio to solve for 11 parts out of 18
11:18 = x:144 Proportion
11 / 18 = x / 144 Equation: Cross mulitiply
11*144 = 18x Combine the left side
1584 = 18x Divide by 18
1584 / 18 = x
88 = x
That is the larger amount (11 is larger than 7)
Find the smaller amount
144 - 88 = 56
The two amounts are in the ratio of 11:7
88:56 = 11:7
