Let R be the rectangle with vertices (0,0), (4,0), (4,4), and (0,4) and let f(x, y)=2xy−−−√. (a) Find reasonable upper and lower bounds for ∫RfdA without subdividing R.

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5

a 90 degree rotation across the the origin followed by a reflection across the x-axis.
