Of course girl! Algebra is my thing :)
The correct answer is B, and here's why:
(a+3)^3 is the same as (a+3)(a+3)(a+3)
(a+3)(a+3)=a(a+3)+3(a+3) (distributive property)
a^2+3a+3a+9=a^2+6a+9
And from there we see that all the values match. Hope this helps

B. (a+3)^2= a^2+ 6a+9 (a+3)= a^3+ 6a^2+9a+3a^2+18a+27= a^3+ 9a^2++27a+27 - ---------------------------------

Find the area of the shaded regions. Give your answer as a completely simplified exact value in terms of pi (no approximations)

Kisachek [45]

Answer:

40π in^2

Step-by-step explanation:

360°/72°=5

so, each of the two shaded regions are 1/5 of the circle.

the formula for finding the area of a circle is πr^2, so:

area for one of the shaded regions:

1/5πr^2

1/5π(10)^2

1/5π100

20π in^2

this means that the area for one of the shaded regions is 20π. however, since there are two of them:

2(20π)=40π

so, the area of the shaded regions is 40πin^2

Serjik [45]

Answer:

The scale used on his map is <u>150 miles : 2 inches</u>.

Step-by-step explanation:

Given:

Ted knows the actual distance between two cities is 150 miles. His map shows a distance of 2 inches between these cities.

Now, to find the scale Ted used on his map.

The actual distance Ted know between two cities = 150 miles.

The distance on map between these cities = 2 inches.

So, to get the scale used on his map:

$\frac{The\ actual\ distance\ Ted\ know\ between\ two\ cities}{The\ distance\ on\ map\ between\ these\ cities}$

$=\frac{150\ miles}{2\ inches}$

$=150\ miles:2\ inches.$

Therefore, the scale used on his map is 150 miles : 2 inches.

A total of h males and (h - 2) females visit the museum on a certain day. If total of visitors for that day is 80, what is the v

Akimi4 [234]

Given:

Number of males = h

Number of females = (h-2)

Total number of visitors = 80

To find:

The value of h.

Solution:

We have,

Number of males = h

Number of females = (h-2)

So, the total number of visitors is:

$Total=h+(h-2)$

$Total=2h-2$

It is given that the total number of visitors is 80. So,

$2h-2=80$

$2h=80+2$

$2h=82$

Divide both sides by 2.

$h=\dfrac{82}{2}$

$h=41$

Therefore, the correct option is D.
