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:
Answer: twenty-four fifths
Step-by-step explanation:
3/5 x 8 → 3/5 x 8/1 (8/1 is the same as 8) → 3 x 8 = 24 and 5 x 1 = 5 so 3/5 x 8 is 24/5
Answer:-45
Step-by-step explanation:
Answer:
(x-7)^2 + (y-2) ^2 = 130
Step-by-step explanation:
We need to find the length of the radius
the length of the radius is found by using the distance formula
r = sqrt( ( -2-7)^2+( -5 -2)^2)
sqrt( ( -9)^2+( -7)^2)
sqrt( 81+49)
sqrt(130)
The formula for a circle is
(x-h)^2 + (y-h) ^2 = r^2
where (h,k) is the center and r is the radius
(x-7)^2 + (y-2) ^2 = 130
Answer:
It is the answer closest to the right. The one with a straight line.
Step-by-step explanation:
Because it is a function if there is only one dot per line vertically. The others have either 2 or more dots per line vertically.
