Answer:

x+x+30 is the required expression.

Step-by-step explanation:

You watch x minutes of television on Monday

An since, the same amount on Wednesday that means x minutes on Wednesday

And 30 minutes on Friday

Since, we have to tell the expression that represents the total amount in the given situation that means

x+x+30 is the required expression.

Evaluate the double integral i=∫∫dxyda where d is the triangular region with vertices (0,0),(4,0),(0,4).

$I=\displaystyle\iint_D\mathrm dA=\int_{x=0}^{x=4}\int_{y=0}^{y=4-x}\mathrm dy\,\mathrm dx$
$I=\displaystyle\int_{x=0}^{x=4}(4-x)\,\mathrm dx$
$I=8$

To verify this, we can simply find the area of the triangle using the well-known formula $\dfrac12bh$ , where $b$ and $h$ are the base and height, respectively of the triangular region $D$ . We have $b=h=4$ , so the area is $\dfrac{4^2}2=8$ , as expected.
