Answer:

x^3 - x^2 - 17x + 12

Step-by-step explanation:

To multiply two polynomials together, first multiply each term of one polynomial by each term of the other polynomial. Then, collect like terms.

(x + 4)(x^2 - 5x + 3) =

Multiply x by each term of x^2 - 5x + 3. Multiply 4 by each term of x^2 - 5x + 3.

= x^3 - 5x^2 + 3x + 4x^2 - 20x + 12

Now collect like terms and write them in descending order of degree.

= x^3 - x^2 - 17x + 12

Find the limit, if it exists, or type dne if it does not exist.

Phantasy [73]

$\displaystyle\lim_{(x,y)\to(0,0)}\frac{\left(x+23y)^2}{x^2+529y^2}$

Suppose we choose a path along the $x$ -axis, so that $y=0$ :

$\displaystyle\lim_{x\to0}\frac{x^2}{x^2}=\lim_{x\to0}1=1$

On the other hand, let's consider an arbitrary line through the origin, $y=kx$ :

$\displaystyle\lim_{x\to0}\frac{(x+23kx)^2}{x^2+529(kx)^2}=\lim_{x\to0}\frac{(23k+1)^2x^2}{(529k^2+1)x^2}=\lim_{x\to0}\frac{(23k+1)^2}{529k^2+1}=\dfrac{(23k+1)^2}{529k^2+1}$

The value of the limit then depends on $k$ , which means the limit is not the same across all possible paths toward the origin, and so the limit does not exist.

Answer:

15/32 cm²

Step-by-step explanation:

Area of rectangle = l × b

=> 3/4 × 5/8

=> 15/32

Therefore,

Area of rectangle is 15/32 cm²
