Answer:
4y^(2)+14y+31
Step-by-step explanation:
First you need to do (y+7)(y+7)
y^2+7y+7y+49
y^2+14y+49
Add it all together
y^2+14y+49+3y^2-15
4y^(2)+14y+31
There are 52 weeks in a year.
Using 50 for the number of weeks in a year is a(n) round.
Rounding is a process which we approximate the known number by just scaling it up or down.
In rounding the numbers less than 5 are scaled to one number less than the given integer and numbers such as 5 or above than 5 are scaled a number greater than the given number .
For example if there were 55 or more than weeks in a year we can say there are approximately 60 weeks in a year.
But there are 52 weeks so we <u><em>round</em></u> it to 50 weeks as 2 is less than 5.

I’ll teach you how to solve 3.26d+9.75d-2.65
——————————————-
3.26d+9.75d-2.65
Collect like terms by adding their coefficients:
(3.26+9.75)d-2.65
Add the numbers:
3.26+9.75= 13.01
13.01d-2.65
Your Answer Is 13.01d-2.65
