If f(x) = x ^ 2 + 3 , then f(x+y)=?
kobusy [5.1K]

Answer:

f(x)=x^2+3

f(x+y)=(x+y)^2+3

this is done by replacing x with (x+y)

f(x+y)=x^2+2xy+y^2+3

therefore : f(x+y)= x^2+y^2+2xy+3

There are 1420 students enrolled at Senn. If 60% of these students walk to school, how many students are walking to school?
pychu [463]

Answer:

852 students walking to school

Step-by-step explanation:

Lets start with a simple example so you can get it

if 60% of 100 students walk to school that means

60 students walk to school... right??

so lets simplify it more that means you have multiplied 100 (students) by 60%

or \frac{60}{100}  (note: you can say that 60% is equal to \frac{60}{100} )

so the problem told 60% of 1420 students walk to school that means we should

do this:     1420*\frac{60}{100} = 852
