Sean's mom asks him how long his homework will take. he tells her that he needs to read for 25 minutes and also do some math problems that will take m minutes. all together, his homework will take h minutes. write an equation for the number of minutes sean's homework will take h, if his math problems take m minutes

h=25+m

Hope this helped I did it on Khan Academy

 The required equation is

Step-by-step explanation:  Given that Sean's mom asks him how long his homework will take.

He tells her that he needs to read for 25 minutes and also do some math problems that will take m minutes. All together, his homework will take h minutes.

We are to write an equation for the number of minutes Sean's homework will take h, if his math problems take m minutes.

Since Sean needs to read for 25 minutes and do some math problem for m minutes, so total time that Sean will take will be

Also, since Sean takes h minutes altogether to complete his homework, so the equation is written as

Thus, the required equation is

the answer is a

step-by-step explanation:

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
