Explain how to use the distributive property to simplify: -2(x + 5) ?
Answer:
-2x-10
Step-by-step explanation:
Distributive Property is basically a term for opening parentheses. So, in your case -2(x+5) we would multiply x and 5 by -2. X times -2 is -2x and 5 times negative 2 is -10. -2x-10 would be your final answer.
[tex]\huge\bold{ANSWER:}[/tex]
-2x-10
[tex]\bf{EXPLANATION:[/tex]
Hi there!
Here's what the Distributive Property states:
a(b+c)=ab+ac
So, we take a number outside the parentheses, and "distribute" it.
In this case, we should distribute -2:
-2(x+5)
-2x-10 (a negative times a negative is a positive)
Hope it helps!
Enjoy your day!
Feel free to ask if you have any doubts! :)

The perimeter of a rectangular pool is 72 meters. If the length of the pool is twice its breadth. Its length is_________.
Answer:
Length = 18 meters
Step-by-step explanation:
Let the length of the rectangular pool = l meters
And breadth of the pool = w meters
Perimeter of the rectangular pool = 2(l + 2w)
Since, perimeter of the rectangular pool is 72 meters.
2(l + 2w) = 72
l + 2w = 36 --------(1)
If length of the pool is twice of its breadth,
l = 2w
w = [tex]\frac{l}{2}[/tex] -------(2)
By substituting the value of 'w' from equation (2) to equation (1),
[tex]l+2\times{\frac{l}{2}}=36[/tex]
2l = 36
l = 18 meters

Write the polynomial in standard form given the following zeros. Show all work.
(hint; the polynomials are of degree 3)

Answer:
x³ - 2x² + 9x - 18x³ - 5x² + 3x + 9Step-by-step explanation:
1.
Zero's
x = -3i, x = 2 and the third zero is x = 3iPolynomial is:
(x + 3i)(x - 3i)(x - 2) =(x² - 9i²)(x - 2) =(x² + 9)(x - 2) =x³ - 2x² + 9x - 182.
Zeros:
x = 3, x = 3, x = -1Polynomial is:
(x - 3)(x - 3)(x + 1) = (x² - 6x + 9)(x + 1) =x³ + x² - 6x² - 6x + 9x + 9 =x³ - 5x² + 3x + 9What is the greatest common factor of 7, 35, and 28?
