15x^7+10y^2 in factored form

Step-by-step explanation:

Since you are dealing with x's in one term and y's in the other, the only thing you can factor out is whatever number is common to both 15 and 10.  That happens to be a 5.  Therefore,

is the simplest this can get.

the one on the bottom left

step-by-step explanation:

all of the other ones have a specific pattern

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
