$3(2x + 8) - 4x \\ = 6x + 24 - 4x \\ = 2x + 24$
Let's see A
$8x + 24 - 6x \\ = 2x + 24$
Let's see B
$2x - 40 + 4 \\ = 2x - 36$
Let's see C
$2x + 20 + 4 \\ = 2x + 24$
Let's see D
$12x + 24 - 10x \\ = 2x + 24$
E. 2x + 24

So the answers are A, C, D and E.

Hope this helps.

Answer:

Since we know that ABCD ~ EFGH, we have the ratios:

EF/AB = GH/CD

=> 0.4/1.2 = x/1.8

=> x = (1.8 . 0.4)/1.2 = 0.6

So x = 0.6

The profits of a company are found by subtracting the company's costs from its revenue. If a company's cost can be modeled by 14

evablogger [386]

Answer:

$-0.0002x^2 +26x-120000$

Step-by-step explanation:

The correct question should be:

We have been told that all we have to do to get profit is to subtract the cost from revenue.

Revenue = $40x - 0.0002x^2$

Cost <em>= </em> $14x + 120,000$ <em />

<em />

Hence:

Profit = $40x - 0.0002x^2 - (14x + 120000)$

$40x - 0.0002x^2 - 14x - 120000\\\\40x - 14x - 0.0002x^2 - 120000\\\\26x - 0.0002x^2 - 120000$

Putting it in ordered form:

$-0.0002x^2 +26x-120000$

This is an expression for the profit.

So I kinda forgot how to do this *nervous laughter* um help

1) value of x =60

2) value of x = 3

Step-by-step explanation:

We need to use cross products to solve the proportions of x.

$1.\,\, \frac{3}{5}= \frac{x}{100}$

Solving:

$\frac{3}{5}= \frac{x}{100}\\Cross\,\,multiply\,\,:\\5x=3*100\\5x=300\\x=\frac{300}{5}\\x=60$

So, value of x =60

$2.\,\,\frac{x}{8}=\frac{7.5}{20}$

$\frac{x}{8}=\frac{7.5}{20} \\20x=7.5*8\\20x=60\\x=\frac{60}{20}\\ x=3$

So, value of x = 3
