The following equation simplified by factoring or distributing:

2x + 6
2x + 6 + 2y
-10x + 15
40w - 5p
4(5 + 8w)
12(7 + 3z)
12(7 + 3z)
4y² - 38y - 20

<h3>Factorization</h3>

1.) 2(x + 3)

= 2x + 6

2.) 2(x + 3 + y)

= 2x + 6 + 2y

3.) −5 (2x − 3)

= -10x + 15

4.) –5(–8w + p)

= 40w - 5p

5.) 20 + 32w

= 4(5 + 8w)

6.) 84 + 36z

= 12(7 + 3z)

7.) (2x - 6)(5x + 7)

= 10x² + 14x - 30x - 42

= 10x² - 16x - 42

8.) (y - 10)(4y + 2)

= 4y² + 2y - 40y - 20

= 4y² - 38y - 20

The population of a city is modeled by the equation P(t)=232012e0.23t where t is measure in years. If the city continues to grow

Gennadij [26K]

In around 6.35 years, the population will be 1 million.

<h3> how many years will it take for the population to reach one million?</h3>

The population is modeled by the exponential equation:

$P(t) = 232,012*e^{0.23*t}$

Then we just need to solve the equation for t:

$P(t) = 232,012*e^{0.23*t} = 1,000,000$

Let's solve that:

$232,012*e^{0.23*t} = 1,000,000\\\\e^{0.23*t} = 1,000,000/232,012 = 4.31\\$

If we apply the natural logarithm to both sides:

$ln(e^{0.23*t}) = ln(4.31)\\\\0.23*t = ln(4.31)\\\\t = ln(4.31)/0.23 = 6.35$

So in around 6.35 years, the population will be 1 million.

1.Use Euler’s Formula to find the missing number. Edges: 40

PtichkaEL [24]

Answer:

Euler's Formula states that:

V -E +F = 2 meaning that the vertices minus the edges plus the faces of a convex polyhedron will always equal two.

So, for the initial question, we have 40 edges and 24 faces.

So, vertices = 2 + Edges -Faces

Vertices = 2 + 40 - 24

Vertices = 18
