2(x − 3) = 14 what does x equal
Answer:
28x--84
hope this helps, have a great day
Step-by-step explanation:
Answer:
x=10
Step-by-step explanation:
2(x − 3) = 14
2x+2 . -3 = 14
2x-16=14
2x-6+6=14+6
2x=14+6
2x=20
divide both sides by 2

Answer:
-(1+x-y)(x-y-1)
Step-by-step explanation:
since both terms are perfect squares, factor using the difference of squares formula
a2 - b2 = (a+b) (a-b) where a = 1 and b= x-y
-(1+x-y)(x-y-1)
Answer:Factor by grouping.

Answer:
(-5)^3 = -125
Step-by-step explanation:
(-5)^3
= (-5) × (-5) × (-5) = -125
= (-5)^3 = -125
(-5) to the power of 3 is just (-5) multiplied by itself 3 times so (-5) to the power of 3 is (-5)^3 which is -125
Step-by-step explanation:
it's quite easy to go around this problem.
first you gotta consider the negative (-) sign..
you know when a negative sign multiplies another negative sign you'll get a positive sign.
example
-5*-5= ?
since you know the negative sign would turn to a positive sign when they multiply each other.
and be mindful of problems with different signs like
−6×9, you'll definitely get a negative answer
Now to your question.
(−5)^3, if you're struggling with composite expression,all you need is to break it down to simplified form
since it's -5 raised to the power of 3
you can as well write it as -5*-5*-5 (pay attention to the negative sign). then go through with your calculations
if you do it correctly, you'll arrive at the answer
-125

How many 5th equals 9
The number of 5ths that equals 9 is gotten bus using multiplication property of equality by multiplying 9 by 5 to give; 45
How to find the number of terms?We want to find the number of 5ths that equals 9. We can express this as;
¹/₅x = 9
Where x is the number that is multiplied with one - fifth to equal 9.
To solve it, we will apply multiplication property of equality by multiplying both sides by 5 to get;
x = 45
Thus, the number of 5ths that equals 9 is 45.

32 times four is 128
Now do 133 - 128 = 5
Drop the 2
What times 32 is 52
Well times two is 64 so it has to be times1
Now you have 52 - 32 to get your quotient of 20
The diagram shows a circle inside a rectangle....
Answer:
let [tex]x[/tex] = height of rectangle
Given:
height of rectangle = diameter of circlelength of rectangle = 3 × height of rectangleTherefore,
height of rectangle = [tex]x[/tex]diameter of circle = [tex]x[/tex]radius of circle = [tex]\dfrac{1}{2}x[/tex]length of rectangle = [tex]3x[/tex]Shaded area = area of rectangle - area of circle
Area of rectangle = length × height
= [tex]3x \times x[/tex]
= [tex]3x^2[/tex]
Area of circle = [tex]\pi r^2[/tex]
[tex]=\pi \left(\dfrac{1}{2}x\right)^2[/tex]
[tex]=\dfrac14\pi x^2[/tex]
[tex]\implies \textsf{shaded area}=3x^2-\dfrac14\pi x^2[/tex]
If the radius = 2 cm, then the diameter ([tex]x[/tex]) = 4 cm
Substituting [tex]x = 4[/tex] into the equation:
[tex]\implies \textsf{shaded area}=3(4)^2-\dfrac14\pi (4)^2[/tex]
[tex]\implies \textsf{shaded area}=48-4\pi[/tex]
[tex]\implies \textsf{shaded area}=4(12-\pi) \textsf{ cm}^2[/tex]

x^2-10=0 solve for all real values of x
this is very hard lol pls help
so x^2-10=0
we add 10 to both sides of the equation x^2 = 10
then take the square root of both sides of the equation to eliminate the exponent on the left side x = ± √10
The complete solution is the result of both the positive and negative portions of the solution. x = √10 ,−√10
the result can be shown in multiple forms
Exact Form :x=√10,−√10x=10,-10
Decimal Form: x=3.16227766…,−3.16227766
