5y (- 9 - 3y) = 13 What is Y?
Murrr4er [49]
To solve this equation, we have to use the distributive property to multiply 5y through the parentheses. 

-45y - 15y^2 = 13

-15y^2 - 45y - 13 = 0 

15y^2-45y-13=0

Round off 4252 to one significant number
Anettt [7]
4252 rounded is 4000.

Explanation:
When it says "significant number", we assume to round to the nearest thousand. To do this, we look at the hundredths place. If the number in the hundredths place is 1-4, we keep the 4000. If the number is from 1-5, we round up to 5000. Since the hundredths place is 2, we round down to 4000.
