Which is a factor of x2 8x – 48? (x – 6) (x 4) (x – 16) (x 12)

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

Answer:

let [tex]x[/tex] = height of rectangle

Given:

Therefore,

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]

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

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.

Step-by-step explanation:

The number of 5ths that equals 9 is gotten bus using multiplication property of equality by multiplying 9 by 5 to give; 45

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.

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:

m = -1

Step-by-step explanation:

3(m + 2) = -( 6- m) + 10​

Distribute

3m +6 = -6+m +10

Combine like terms

3m+6  = m+4

Subtract m from each side

3m-m+6 = m+4-m

2m+6 = 4

Subtract 6 from each side

2m+6-6 = 4-6

2m = -2

Divide by 2

2m/2 = -2/2

m = -1
