Multiply.
(2x + 4)(x - 4)
Answers
Answer:
-2x-16
Step-by-step explanation:
so what you are going to do for this is use the distributive property. 2x will be multiplied by x and -4. then you will take 4 and multiply x and -4. then you combine your alike terms. 2x-8x+4x-16 you should get -2x-16
The equivalent expression after multiplying is 2(x² - 2x - 8).
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
(2x + 4) (x - 4)
Remove the parenthesis.
2x² - 8x + 4x - 16
Add like terms.
2x² - 4x - 16
Taking out the common factor.
2 (x² - 2x - 8)
Thus,
The final expression is 2(x² - 2x - 8).

A rectangular prism has a square base with side length s units. It also has the curious property that the numerical value of the sum of its edge lengths (in units) is equal to the numerical value of its surface area (in square units).
If one edge of the prism has length 8 units and s 6= 8, then s can be written in the form a + √b, where a and b are integers. Find a + b.

What is the slope of a line parallel to the line whose equation is 22 - y = 7. Fully
reduce your answer.
Answers
Answer:
The slope of the parallel line is 2
Step-by-step explanation:
Parallel lines have equal slopes, so for this question you need to re-format the equation to match a y=mx+b format (slope-intercept form).
2x -y = 7 | Subtract 2x from both sides
-y = 7 + 2x | Multiply by negative one to make y even
y = 7 + 2x | Rearrange the equation to match the formula
y = 2x +7 | 2 is your slope for both parallel lines!

What is the difference between upward, downward, leftwards and rightwards translation?Upward translation : [k] units = When the upward translation take's place then, each point will have its y - coordinate shifted upwards by +k units.Downward translation : [k] units = When the downward translation will take place then, each point will have its y - coordinate shifted downwards by -k units.Leftward Translation : [k] units = When the leftward translation will take place then, each point will have its x - coordinate shifted by -k units to the left.Rightward Translation : [k] units = When the rightward translation will take place then, each point will have its x - coordinate shifted by +k units to the right.Given is that pentagon ABCDE ≈ pentagon FGHIJ.
Since the pentagons are similar, we can say that the corresponding angles will be equal. So, we can write -
∠1 = 100°
Therefore, the measure of ∠1 is equivalent to 100°.

When Michael Jordan retired from basketball he had the third highest scoring total in NBA history at 32,292 points an average 30 points per game for his whole career. However, Kobe Bryant passed Jordan on the list for third place with 33,643 points before COBE retired. If Michael Jordan started playing again, how many games would he have to play to catch cobia for third place? (You must write an equation and show you were to support your answer)
Answers
9514 1404 393
Answer:
46 games
Step-by-step explanation:
Let g represent the number of games played at 30 points per game. Then Jordan's total score would be
32292 +30g
We want to find the value of g that makes this total 33,643:
32292 +30g = 33643
30g = 1351
g ≈ 45.03
Jordan would have to play 46 games to regain 3rd place.
_____
After 45 games, Jordan's point total would be 33,642, which is 1 point short of Bryant's record.
