Answer:

(2x-5)(4x^2+10x+25)

Explanation:

Factoring difference of cubes (a3−b3): (a−b)(a2+ab+b2)

Here, a is 2x because the cube root of 8 is 2 and the cube root of x3 is x, b is 5 because the cube root of 125 is 5.

Plug the numbers in:

(2x−5)((2x)2+2x⋅5+52)

(2x−5)(22x2+10x+25)

(2x−5)(4x2+10x+25)

Answer:

8x^3 can also be written as [tex](2x)^{3}[/tex].

-125 can also be written as [tex]-5^{3}[/tex].

Factoring the polynomial:

[tex](2x)^3+(-5)^3[/tex]

=======================================================

Explanation:

The angles (2x+24) and x are same side interior angles. Same side interior angles are supplementary when we have parallel lines.

(2x+24) + (x) = 180

2x+24+x = 180

3x+24 = 180

3x = 180-24

3x = 156

x = 156/3

x = 52

Answer:

7280000000 or 7.28^9 (in scientific notation)

Step-by-step explanation:

this question is asking you to transfer numbers out of scientific notation and multiply them. 10^6 is 1 followed by 6 zeros (good trick to remember) or 1000000. when you multiply anything by a power of 10 you just add that many zeroes to it or move the decimal point one point to the left for every zero. so in this example it is 5.2 times 1000000 which is 5200000. we do the same for the other one and we get 1400. When we multiply these two values we get 7280000000 or 7.28^9

Answer:

  J' = (-2, 4)

Step-by-step explanation:

The transformation for 270° counterclockwise rotation about the origin is ...

  (x, y) ⇒ (y, -x)

The point J is (-4, -2), so the point J' is ...

  J' = (-2, -(-4))

  J' = (-2, 4)

Given:

Lilly starts hiking along a trail at 3 miles per hour.

Dave starts hiking the same trail from the same starting point at 3.5 miles per hour.

lilly walked 2 miles before Dave started hiking.

To find:

Whether he will catch up to her and write an equation.

Step-by-step explanation:

Let the number of hours when both are hiking be h.

lilly walked 2 miles before Dave started hiking at 3 miles per hour.

Lilly hiking = 2+3h

Dave starts hiking the same trail from the same starting point at 3.5 miles per hour.

Dave hiking = 3.5 h

He will catch her if hiking distance of both are equal.

[tex]2+3h=3.5h[/tex]

Subtract 3h from both sides.

[tex]2=3.5h-3h[/tex]

[tex]2=0.5h[/tex]

Divide both sides by 0.5.

[tex]\dfrac{2}{0.5}=h[/tex]

[tex]4=h[/tex]

Therefore, Dave will catch her after 4 hours.

Dave will catch up Lilly after 4 hours.

Since Lilly starts hiking along a trail at 3 miles per hour, and Dave starts hiking the same trail from the same starting point at 3.5 miles per hour, if Lilly walked 2 miles before Dave started hiking, to determine when he will have catch up to her the following calculation must be performed:

Therefore, Dave will catch up Lilly after 4 hours.

Step-by-step explanation:

In order to describe speed of an object, we must describe the average speed of the entire trip. It is equal to the distance moved divided by time taken.

If a person covers a distance of 1 km to the library in 15 minutes, we can find its average speed.

Firstly, we convert 15 minutes to hour, 15 min = 0.25 hours

Now, using formula of speed = distance/time

[tex]v=\dfrac{1\ km}{0.25\ h}\\\\v=4\ km/h[/tex]

It means that the average speed of the person is 4 km/h. Hence, the given statement is true.

Answer:

x = 7

Step-by-step explanation:

7x-1+6x=90

Combine like terms

13x-1 = 90

Add 1 to each side

13x-1+1 = 90+1

13x = 91

Divide by 13

13x/13 =91/13

x = 7

Answer:

The numerical length of MO is 20 units

Step-by-step explanation:

Let us solve the question

∵ Point N is on line segment MO

→ That means point N divides segment MO into two parts MN and NO

∴ MO = MN + NO

∵ MO = 2x + 5

∵ MN = 2x + 3

∵ NO = 2x - 3

→ Substitute them in the equation above

∴ 3x + 5 = (2x + 3) + (2x - 3)

→ Add the like terms in the right side

∵ 3x + 5 = (2x + 2x) + (3 - 3)

∴ 3x + 5 = 4x + 0

∴ 3x + 5 = 4x

→ Subtract 3x from both sides

∵ 3x - 3x + 5 = 4x - 3x

∴ 5 = x

∴ The value of x is 5

→ To find MO substitute x by 5 in its expression

∵ MO = 3x + 5

∴ MO = 3(5) + 5

∴ MO = 15 + 5

∴ MO = 20 units

The numerical length of MO is 20 units

Answer:

72/b = h

Step-by-step explanation:

plug in known values

A = 1/2 (bh)

36 = 1/2 (bh)

goal is to isolate the variable h (height)

multiply both sides by 2 to cancel out 1/2

36 × 2 = 1/2 × 2 (bh)

72 = bh

divide both sides by b (base)

72/b = bh ÷ b

72/b = h

i dont see the value for base given so this would be the final answer as far as i know

c = 208.8

Step-by-step explanation:

a. [tex]\frac{c}{7.2} =29[/tex]   To solve for C, you need to get the variable on one side of the equation and the numbers on the other side of the equation.

b.  [tex]\frac{c}{7.2} =29[/tex]   You need to move the 7.2 to the other side. So, multiply both sides by 7.2, because it's being divided, so multiplying will cancel it out.

c:  [tex]c = 29 * 7.2[/tex]   Then, multiply 7.2 by 29. (The * symbol means multiply)

d.  c. = 208.8   The answer is 208.8, which is rounded to the tenths place.

[tex](6 - 2) \times 180 = 4 \times 180 = 720 \\ [/tex]

So the sum of the nterior angles of the figure must equal 720° :

[tex](x - 8) + 4x + 2x + 3x + 2x + 2x = 720 \\ [/tex]

[tex]14x - 8 = 720[/tex]

Plus both sides 8

[tex]14x = 728[/tex]

Divided both sides by 14

[tex]x = \frac{728}{14} = 52 \\ [/tex]

So ;

[tex]x = 52[/tex]

Answer:

This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by 4

gives the next term. In other words,

an=a1.rn-1.

Geometric Sequence:

R=4

This is the form of a geometric sequence.

an=a1rn-1

Substitute in the values of

a1=11 and

r=4.an=(11)(.)4)n-1

Remove parentheses.
