What is 4(k+3)+2=4.5(k+1) ?

1 answer:

3 0

K = 19. When you follow order of operations you start with Parenthesis.
So, plug in 19 first. (19+3) = 22 and (19+1)=20.

From there, you multiply the number outside the parenthesis.
22 * 4 = 88 + 2 = 90

Do the math on the other side now.
20 x 4.5 = 90

Considering they both equal 90, your problem is complete, and your answer for K is 19.

I hope this helps (:

The polynomial of degree 3, P(x), has a root of multiplicity 2 at x=5 and a root of multiplicity 1 at x=−5.

Answer:

P(x) = $-0.7(x-5)^{2}(x+5)$

Step-by-step explanation:

Root multiplicity of 2 means the root is repeated 2 times. Root multiplicity of 1 means root is repeated only once.

A polynomial of degree 3 means the largest exponent of x is 3.

Here, the polynomial P(x) has root 5 with multiplicity 2 and -5 with multiplicity 1.

So, P(x) = $a(x-5)^{2}(x+5)$

Where, $a$ is a constant.

Now, it's given that the y intercept is -87.5. Therefore, value of x at y intercept is 0.

We obtain $a$ by plugging in -87.5 for P(x) and 0 for x.

$-87.5=a(0-5)^{2}(0+5)$

$-87.5=a(25\times5)\\ a=-\frac{87.5}{125}=-0.7$

Therefore, the polynomial P(x) is given as:

$P(x) =-0.7(x-5)^{2}(x+5)$

a company is packing cartons of candles. each carton can hold 75 candles. so far, 50 cartons have been packed, but only 30 carto

Alinara [238K]

If theres 50 cartons in total and 30 have been loaded then 20 have not.

20 x 75 = 1,500

So the answer is 1,500 candles.

Simplify a^2-3a2 a^3-8a^2+12a to lowest terms

inn [45]

Answer:

$\frac{a-3}{(a-2)(a-6)}$

Step-by-step explanation:

$a^{2}-3a$ has the common multiple of a. If you factor it out, you get $a(a-3)$ .

$a^3-8a^2+12a$ also has a common multiple of a. Once factored, you get $a(a^2-8a+12)$ . This equation can be further factored to get $(a-2)(a-6)$ .

Put these two expressions over one another and you get $\frac{a-3}{(a-2)(a-6)}$ .
