Is this all one equation?

If it isn't, here:

-6x ^ 2 - 4x <-- Equation 1

18 - 9 + 18 - 9 = 18 <-- Equation 2

If it is:

-5x + x - 6x ^ 2 + 6 * 3 - 4 - 5 + 18 - 9

-4x - 6x ^ 2 + 18 - 9 + 18 - 9

-4x - 6x ^ 2 + 18

Then we order it

-6x ^ 2 - 4x + 18

The proof that the area of the trapezium is 2x² + x -351 = 0 can be seen in the image attached below.

<h3>What is a trapezium?</h3>

A trapezium is a quadrilateral that has a pair of opposite parallel sides.

From the given diagram:

The area of the trapezium can be computed as;

$\mathbf{= \dfrac{1}{2} \times (sum \ of \ the \ parallel \ sides) \times height }$

$\mathbf{351= \dfrac{1}{2} \times (x-4 + x +5) \times 2x }$

$\mathbf{351= \dfrac{1}{2} \times (2x+1) \times 2x }$

$\mathbf{351= (2x+1) \times x }$

351 = 2x² + x

2x² +x - 351 = 0 : Proved

In the winter, Grandma Helen knits scarves for her family members. It took her 70 minutes to make a 35-inch-long scarf for her g

melomori [17]

Answer:

100 minutes

Step-by-step explanation:

Set up a proportion where x is the amount of minutes it will take her to make the 50 inch long scarf:

$\frac{70}{35}$ = $\frac{x}{50}$

Cross multiply and solve for x:

35x = 3500

x = 100

So, it will take her 100 minutes to make Shannon's scarf

After years of maintaining a steady population of 32,000, the population of a town begins to grow exponentially. After 1 year an

qwelly [4]

Answer:

y = 32,000(1.08)^x

Step-by-step explanation:

The exponential growth equation is y = a(1 + r)^x, where a is the initial amount, r is rate as a decimal, and x is the time.

In this situation, 32,000 is the initial amount (a) and 0.08 is the rate (r)

If we plug these into the equation, we get the equation y = 32,000(1.08)^x

So, y = 32,000(1.08)^x is the correct answer.
