(x-5)(x-6)

Step-by-step explanation:

-6-5=-11

-6 times -5=30

so...

(x-5)(x-6) and -5 and -6 are the factors.

Answer:

8.24 is not a rational number

Step-by-step explanation:

The simple way to remember or find if the number is rational or not is that

* Rational numbers are always in the form of p/q and q should not be equal to zero

here u can even see 8.24 can be written as 8.24/0 so it is clearly showing that it is not a rational number

Answer:

25.6 feet

Brainliest, please!

Step-by-step explanation:

10/16 = 16/x

5/8 = 16/x

5 = 128/x

x = 128/5

x = 25.6

The floor of the new tent is 24 feet wide.

Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.

If a and b are two values, their ratio will be a:b.

Given that,

Side of old tent = 10 feet,

And width of floor = 15 feet.

Let width of new tent is x feet.

To find the width of a tent whose side is 16 feet,

Use ratio and proportion property,

10/15 = 16/x

x = (16 × 15)/10

x = 240/10

x = 24 feet

The width of the floor of the new tent is 24 feet.

Answer:

It is c: 15.625 cm³

Step-by-step explanation:

Formular for cube volumes:

[tex]{ \tt{volume = (side \times side \times side)}} \\ { \tt{v = (s_{1} \times s_{2} \times s_{3}) }}[/tex]

since sides of a cube are identical:

[tex]{ \sf{s_{1} = {s_{2} = {s_{3}}}}}[/tex]

Therefore:

When multiplying exponents, add the exponents together.

When dividing exponents, subtract the exponents.

Solve:

Given expression

(3 × 10⁴) × (1.1 × 10⁵)

Put like terms together

Step-by-step explanation:

Answer:

n = 3

Step-by-step explanation:

to find the value of n

we need to transpose

7n + 12 = 3n+ 8n

7n + 12 = 11n

12 = 11n -7n

12 = 4n

n = 12/4

n = 3

if ur trying to find the value of n then n=3

Answer:

y=16

Step-by-step explanation:

Multiply all terms by the same value to eliminate fraction denominators

Cancel multiplied terms that are in the denominator

Re-order terms so that constants are on the left

Divide both sides of the equation by the same term

Simplify

Cancel terms that are in both the numerator and denominator

Divide the numbers

Answer:

y is 16

Step-by-step explanation:

[tex]4 = \frac{64}{y} [/tex]

but 64 is 4³:

[tex]4 = \frac{ {4}^{3} }{y} [/tex]

make y the subject:

[tex]y = \frac{ {4}^{3} }{4} [/tex]

from law of indices:

[tex]y = 4 {}^{(3 - 1)} \\ y = {4}^{2} \\ y = 16[/tex]

Answer:

x is less than or equal to 4. Not sure how you would type that out on the slide though. :\

Step-by-step explanation:

Answer:

George Washington 67 and sister 63

Answer: 28

Step-by-step explanation:

Let the present age of George be = x years

and present age of her daughter is = y years

4 years ago,

George age be = x - 4

Daughter age be = y - 4

After four years,

George age be = x +4

Daughter age be = y+ 4

Substitute the value of x in equation 2

➡

Value of y put in equation 1

➡x= 28

So, the present age of George is 28 years and his daughter's age is 4 years.

Answer: FH = 16

Concept:

Bisect means to cut or divide something into two equal parts.

In mathematics, usually bisect means cutting a segment or an angle.

If you are still confused, you may refer to the attachment below for a graphical explanation or tell me.

Solve:

Given information

FG is 16 less than 3 times the length of GH

Let x be the length of GH

Given expression

FG = GH

Set equation

3x - 16 = x

Add 16 on both sides

3x - 16 + 16 = x + 16

3x = x + 16

Subtract x on both sides

3x - x = x + 16 - x

2x = 16

Divide 2 on both sides

2x / 2 = 16 / 2

x=8

--------------------------------------------------------------------------------------------------------------

Concept:

In order to find the length of FH, we need to know the idea of the segment addition postulate.

The Segment Addition Postulate states that given 2 points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC.

Solve:

Given information

FG = GH = x

x = 8

Given expression deducted from the segment addition postulate

FH = FG + GH

Substitute values into the expression

FH = x + x

FH = 8 + 8

[tex]\boxed {FH=16}[/tex]
