1. f(x)*g(x)

\sqrt{x^{2}+12x+36}*x^{3}-12

(x^{2}+2\sqrt{3}x+6)*(x^{3}-12)

(x^{3}-12)(x^{2}+2\sqrt{3}x+6)

(x^{3}-12)(x^{2}+2\sqrt{3}x+6)\\\\x^5+2\sqrt{3}x^4+6x^3-12x^2-24\sqrt{3}x-72\\

Hi this is algebra math. It’s been a while since I’ve been on this app but I need some help on if the problem graphed the slope
Umnica [9.8K]
The graph is wrong, the slope is correct but because the sign is less than y that means the line on the graph should be dotted not solid.

This year, a company produced 8 percent more items than last year. If the company produced 243 items this year, how many items d
Ilya [14]

Answer:

Last year company produce 225 items

Step-by-step explanation:

let the number of items produced last year be x

Here we are asked to find the percent increase in the production of the items from last year  

The production for the last year = x

The production for the current year = 243

Total increased production =243-x

Hence percentage calculation = \frac{\increase \in \sale}{\last \year \sale} \times 100 %

Increased percentage = \frac{243-x}{x} \times 100 %

Percentage increased = 8 %

Hence

\frac{243-x}{x} \times 100 = 8

{243-x}\times 100 = 8 \times x

24300-100x = 8x

24300=100x+8x

24300=108x

x= \frac{24300}{108}

x=225

Hence Last year production was 225 items

Which is a correct first step in solving 5 – 2x < 8x – 3?
Elenna [48]

5 < 10x - 3

Step-by-step explanation:

5 - 2x < 8x - 3

Add '2x' to both the sides

5 - 2x + 2x < 8x + 2x - 3

5 < 10x - 3

Find the perimeter of the triangle​
ArbitrLikvidat [17]

Answer:

60 ft

Step-by-step explanation:

(x+13) = (3x-1) = (6x-22) since the triangle is equaililateral

(x+13) = (3x-1) (we only need to chose 2)

-2x=-14

x=7

after this, we just need to plug in the number for x

3(7)-1= 20--->since the triangle has 3 congruent sides, they all have the distance, so 20x3=60

<u><em>60FT</em></u>

Find a nonpermissible replacement for y in this expression y-3/y+3
Darya [45]

the denominator (bottom) of the fraction cannot have the value 0.  Division BY zero is undefined. The question becomes, then, what value of y makes y - 3 = 0?


Solve that equation for y by adding 3 to both sides, and you get y = 3. That is the nonpermissible replacement for y
