Simplify
x² - 9 / х^2 - 3x
Answer:
[tex]\frac{x+3}{x}[/tex]
Step-by-step explanation:
Factorise numerator and denominator
x² - 9 ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , then
x² - 9
= x² - 3² = (x - 3)(x + 3)
x² - 3x ← factor out x from each term
= x(x - 3)
Then
[tex]\frac{x^2-9}{x^2-3x}[/tex]
= [tex]\frac{(x-3)(x+3)}{x(x-3)}[/tex] ← cancel common factor (x - 3) on numerator/denominator
= [tex]\frac{x+3}{x}[/tex]

|15-12|/4 = 3/4
|(-21+9)/8| = |-12/8| = 12/8 = 3/2 (Simply)
3/4 - 3/2 = -3/4
So the answer is B.

in a sale, the normal price of a hat is reduced by 15%
The sale price of the hat is 20.40 euros.
Work out the normal price of the hat.
Answer:
The correct answer is 24
Step-by-step explanation:
To solve this math problem, you will need to divide 20.40 with 1 (1 is 100% as a decimal) and 0.15 (0.15 is 15% as a decimal).
--
[tex]20.40[/tex] ÷ [tex](1-0.15)[/tex]
--
First, subtract 1 and 0.15
[tex]1-0.15=0.85[/tex]
Next, divide 20.40 and 0.85
[tex]20.40[/tex] ÷ [tex]0.85 = 24[/tex]
--
Therefore, the final product of this math problem is 24

Q16. Find x^2 + 1/x^2 , if x + 1/x = 3
Answer:
[tex] 2 \times x \times \frac{1}{x} = 2 \\ {x}^{2} + {y }^{2} + 2xy = {(x + y)}^{2} \\ {x}^{2} + \frac{1}{ {x}^{2} } + 2 = {(x + \frac{1}{x} })^{2} = {3}^{2} = 9[/tex]

solve for x pleaseeee
Answer:
D
Step-by-step explanation:
15^2 = 15 x 15 = 225
12^2 = 12 x 12 = 144
144 + 225 = 369
369 squared = 19.2
solve the inequality. -1/3w ≤ -5
Answer:
[tex] \frac{ - 1}{3} w \leqslant - 5[/tex]

[tex]w \leqslant - 5 \times - 3[/tex]
[tex]w \leqslant 15[/tex]
3+x=2–3x how many solutions and the answer thank you
Answer:
[tex]1[/tex] solution
Step-by-step explanation:
Let's try to solve this and see where we get.
We can add 3x to both sides of the equation to get [tex]3+4x=2[/tex].
We can then subtract 3 from both sides of the equation to get [tex]4x=-1[/tex].
We lastly divide both sides of the equation by 4 to get [tex]x=-1/4[/tex].
Because all of our steps are reversible(for instance, when we divide by 4, we can multiply(the "reverse" of division) by 4, so dividing by 4 is reversible), there is only [tex]\boxed{1}[/tex] solution, [tex]x=-1/4[/tex].

The mean of four numbers is 30. If three of the numbers are 12, 50, and 48, what is the fourth number?
A. 120
B. 10
C. 12
D. 30
Answer:
Here’s the answer:
Step-by-step explanation:
The sum of the four numbers divided by 4 is equal to the mean.
the sum/4 = mean
(12 + 50 + 48 + n)/4 = 30
(110 + n)/4 = 30
(110 + n) = 30 × 4
(110 + n) = 120
n = 120 - 110
n = 10
