Answer:
D -13
Step-by-step explanation:
5x - 3y - z if x = -2, y = 2, and z = -3
5x - 3y - z =
= 5(-2) - 3(2) - (-3)
= -10 - 6 + 3
= -16 + 3
= -13

Hey there!
In order to convert a fraction into a decimal, simply divide the numerator by the denominator. The numerator is the top part of the fraction while the denominator is the bottom part of the fraction.
So, 93 ÷ 1000 = 0.093
Thus, the decimal form of

is 0.093.

Answer: (x + 7)(x - 7)
Explanation: If a variable is taken to an even power, that variable is a perfect square. In this case, x² would therefore be a perfect square.
Since 49 is also a perfect square, what we have here is the difference of two squares. That can be factored as the product of two binomials one with a plus in the middle and one with a minus in the middle.
In the first position will be the factors of x² that are the same.
So we have <em>x</em> and <em>x</em>.
In the second position we will have the
factors of 49 that are the same, 7 and 7.
(x + 7)(x - 7) is your answer which is a factored version of x² - 49.
