Why did the French explore and colonize parts of North America? A.
to enslave Native Americans as workers in France

B.
to establish a democratic republic

C.
to build cattle ranches

D.
to look for gold and trap for furs

Answers

Answer:

Option D.

Step-by-step explanation:

To look for gold and trap for furs, is the right answer.

The French initially came to the United States as explorers, who were trying to find a route to the Ocean and resources. The French finally attempted to build some colonies throughout North America that abandoned, due to various reasons such as disease, weather or struggle with other European authorities. Though during the course of time, they established colonies in the Americas, their initial motive was to look for gold and trap for furs.

I think it would be b because that is what the french explores did back then

Express (x-1)(x+2)(x-3) in standard form

Answers

I hope this helps you



(x.x+2x-1.x-1.2)(x-3)


(x^2+x-2)(x-3)


x^2.x-3.x^2+x.x-3.x-2.x-2. (-3)


x^3-4x^2-5x+6

Answer:

x^3-2x^2-5x+6

Step-by-step explanation:

(x-3)(x-1)

(x^2-x-3x+3)(x+2)

x^3+2x^2-4x^2-8x+3x +6

now combine like terms

-8x + 3x = 5x

2x^2-4x^2= -2x^2

If QRST is a rectangle, find the value of x if angle Q is equal to 5x+30

Answers

A rectangle is a four-sided flat shape where every angle is a right angle (90°). 

QRST = 90^0 

5x + 30 = 90   

5x = 60    

5x = 60 / 5

x = 12
If QRST is a rectangle then Q = 90°.

Threfore

5x + 30 = 90    |subtract 30 from both sides

5x = 60    |divide both sides by 5

x = 12
