Answer:
Part 1)

Part 2)

Step-by-step explanation:
Part 1)
We would like to multiply:

Distribute each term from the first group into the second group. So:

Distribute further:

Combine like terms:

Simplify:

Part 2)
We would like to divide:

Using long division.
Please refer to the attached document.
For the first step, x goes into 2x³ 2x² times. Hence, we multiply our divisor by 2x².
Next, x goes into -6x^2 -6x times. Hence, we multiply our divisor by -6x.
Finally, x goes into -7x -7 times. So, we multiply our divisor by -7 and we simplify.
Therefore:
I'm not exactly sure what you're asking but <em />I'll give it a go.
A = x -6
Answer:
2/3 because the angles are complementary
Step-by-step explanation:
No matter what the measure of the angle is cos(x) will always equal sin(90-x).
Answer:
y = 2*x + 4
Step-by-step explanation:
We know that a linear function can be written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
We know that if this line passes through the points (x₁, y₁) and (x₂, y₂) the slope can be written as:
a = (y₂ - y₁)/(x₂ - x₁)
So, here we know that our line must pass through the points (-2,0) and (0, 4)
Then the slope of this line is:
a = (4 - 0)/(0 - (-2))
a = 4/2 = 2
Then our line is something like:
y = 2*x + b
Now, to find the value of b we can use one of these two points, for example if we use the point (-2, 0), we know that, when x = -2, we must have y = 0.
0 = 2*(-2) + b
0 = -4 + b
4 = b
Then the equation for our line is:
y = 2*x + 4
