Please help me! I will mark brainliest! I don't get polynomials and all that other stuff. So this question is really hard.

frez [133]

Answer:

Using sum and product method you can simplify the top as:

x^2-4x-5 = (x-5)(x+1) and x^2-5x+4 = (x-4)(x-1)

The x-4 and the x+1 cancel each other out and you will be left with

(x-5)/(x-1)

Kamila [148]

$\mathbf f(x,y,z)=e^x\sin y\,\mathbf i+e^x\cos y\,\mathbf j+yz^2\,\mathbf k$

By the divergence theorem, the surface integral can be evaluated by computing the triple integral

$\displaystyle\iint_Sf(x,y,z)\,\mathrm dS=\iiint_V\nabla\cdot\mathbf f(x,y,z)\,\mathrm dV$
$=\displaystyle\iiint_V\left(\dfrac{\mathrm d\mathbf f}{\mathrm dx}+\dfrac{\mathrm d\mathbf f}{\mathrm dy}+\dfrac{\mathrm d\mathbf f}{\mathrm dz}\right)\,\mathrm dV$
$=\displaystyle\int_{x=0}^{x=4}\int_{y=0}^{y=3}\int_{z=0}^{z=4}2yz\,\mathrm dz\,\mathrm dy\,\mathrm dx$
$=72$

Lina20 [59]

In this question, it is given that

Walter wants computer software that cost $129. He has $57 saved.

he saves a maximum of $15 a week, the following inequality can be used to find how many weeks it will take Walter to save enough money to buy the software.

$15x+57 \geq 129$

And we have to solve this inequality for x.

First we subtract 57 to both sides. And on doing so , we will get

$15x\geq 72$

Dividing both sides by 15.

$x \geq 4.8$ \

Correct option is A.
