The base of a triangle is 4x+6cm,the height is 5cm. What is the actual length of the base

After talking with you here are two different options I think you are trying to ask:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

If you are talking about: [tex](\frac{-12}{3}) ^{3}[/tex]

Answer: -62

Explanation:

PEMDAS tells us we need to do the exponent first:

-12³ = (-12)³ = -1728

The parentheses are important so you cube the negative sign as well!

3³ = 27

-1728 / 27 = -62

                           [tex](\frac{-12}{3}) ^{3}[/tex] simplified is -62

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

If you are talking about (-1[tex]\frac{2}{3}[/tex])³

Answer: -[tex]\frac{125}{27}[/tex]

Explanation:

First, let us turn -1 and two thirds into a mixed number:

Ignoring the negative for now, we can 1 times 3 is 3. 3 plus 2 is 5. 5/3 is 5/3. Adding in the negative we get [tex]-\frac{5}{3}[/tex]

To cube it we must do:

([tex]-\frac{5}{3}[/tex])([tex]-\frac{5}{3}[/tex])([tex]-\frac{5}{3}[/tex])

3 times 3 (9) times 3 is 27

5 times 5 (25) times 5 is 125

So we have 125/27

For the negative, we have three - - -

Two cancel each other out, and we are left with one (-) so our answer is negative

                           (-1[tex]\frac{2}{3}[/tex])³ simplifed is -[tex]\frac{125}{27}[/tex]

Answer:

-2

Step-by-step explanation:

As per the provided information in the given question, we have a linear equation. We have to find the value of x.

Basically, transposition method is used to solve a linear equation in one variable containing constants and variables. We just transpose the values from RHS to LHS by changing its arithmetic operators. In this way, we solve for the unknown value. During transposing the values, ( + ) changes to ( – ) and vice-versa ; ( × ) changes to ( ÷ ) and vice-versa.

Now, coming back to the question. We have,

[tex]\longmapsto \rm { 3x = \dfrac{x}{2}- 5} \\ [/tex]

Taking the LCM in RHS and performing subtraction.

[tex]\longmapsto \rm { 3x = \dfrac{x - 10}{2}} \\ [/tex]

Transposing 2 from RHS to LHS. Its arithmetic operator will get changed.

[tex]\longmapsto \rm { 3x \times 2 = x - 10} \\ [/tex]

Performing multiplication in LHS.

[tex]\longmapsto \rm { 6x = x - 10} \\ [/tex]

Transposing x from RHS to LHS. Its arithmetic operator will get changed.

[tex]\longmapsto \rm { 6x - x = - 10} \\ [/tex]

Performing subtraction of the terms in LHS.

[tex]\longmapsto \rm { 5x = - 10} \\ [/tex]

Transposing 5 from LHS to RHS. Its arithmetic operator will get changed.

[tex]\longmapsto \rm { x = \cancel{\dfrac{- 10}{5}}} \\ [/tex]

Dividing –10 by 5.

[tex]\longmapsto \underline{\boxed{\bf { x = - 2}}} \; \bigstar \\ [/tex]

Therefore, the value of x is –2.

Answer:

104 m²

Step-by-step explanation:

There is a 1 m sidewalk around the garden

Then length = 30 + 1 + 1 = 32 m

and width = 20 + 1 + 1 = 22 m

Area = 32 × 22 = 704 m²

Area of garden = 30 × 20 = 600 m²

Area of sidewalk = 704 - 600 = 104 m²

Answer:

p<-12/5

Step-by-step explanation:

Answer:

Multiply each term in [tex]-\frac{5}{6}p > 2[/tex] by [tex]-\frac{6}{5}[/tex] to eliminate the fractions.

Inequality form:

[tex]p < \frac{-12}{5}[/tex]

Interval Notation:

(-∞, [tex]-\frac{12}{5}[/tex] )

Answer:

(- 1, 5 )

Step-by-step explanation:

Given the 2 equations

x + 2y = 9 → (1)

5x - y = - 10 → (2)

Multiplying (2) by 2 and adding to (1) will eliminate the y- term

10x - 2y = - 20 → (3)

Add (1) and (3) term by term to eliminate y

11x + 0 = - 11

11x = - 11 ( divide both sides by 11 )

x = - 1

Substitute x = - 1 into either of the 2 equations and solve for y

Substituting into (1)

- 1 + 2y = 9 ( add 1 to both sides )

2y = 10 ( divide both sides by 2 )

y = 5

solution is (- 1, 5 )

x + 2y = 9 x + 2y = 9

=====》

5x - y = - 10 (×2) 10x - 2y = - 20

+____________

11x + 0 = - 11

11x = - 11

x = - 1

Thus :

- 1 + 2y = 9

Add both sides 1

2y - 1 + 1 = 9 + 1

2y = 10

Divide both sides by 2

2y ÷ 2 = 10 ÷ 2

y = 5

D

Given :-

To Find :-

Answer :-

A) 5x² - 2x

= x ( 5x -2 )

B) x² - 12x -45

= x² -15x + 3x -45

= x(x -15) +3( x -15)

= (x-15) ( x +3)

C) 2x² - x -15

= 2x² +5x - 6x -15

= x(2x +5) -3(2x +5)

= (x-3)(2x+5)

D) 9x² -16

=(3x)² -4²

= (3x+4)(3x-4) [using a²-b² = (a+b)(a-b) ]

Answer:

128 pieces can be made after cutting the chain

Solution:

Given that, Amy cut 32 ft of chain into pieces that were each 1/4 ft long

To find: Number of pieces after cutting the chain

From given,

total length of chain = 32 feet

length of 1 piece = 1/4 feet

Thus the number of pieces after cutting the chain can be found by dividing the total length of chain by length of 1 piece

number of pieces = total length of chain/length of 1 piece

Substituting the values, we get

number of pieces =  [tex]\frac{32}{1/4}[/tex]

number of pieces = 32 x 4 =128

Thus 128 pieces can be made after cutting the chain

Answer:

x=130º

Step-by-step explanation:

90+40+50=180

180-50=130

Answer:

1. y = 90x

x: the amount of companies to start

y: The total amount it will cost.

2. y = 30x

y: the total income

x: the amount of sweaters being sold.

The answer to the last question(I think would be):

cost:  $30

income: $60

as:

equation to find cost = y = -15x

equation to find income = y = 30x

Answer:

Step-by-step explanation:

Let Colin - x, Dan - y, David - z.

We have:

Substitute and solve for z:

Now find x and y:

Answer:

£12

Step-by-step explanation:

Let the David's money be x

If David gets = x

Dan will get = 3x

Colin gets = 3x x 2

= 6x

So, the total money can be write as

[tex]x + 3x + 6x = 10x[/tex]

So, now let's find the amount of money which David have

[tex]10x = 20 \\ \frac{10x}{10} = \frac{20}{10} \\ x = 2[/tex]

So, David will get £2

And now let's find the amount of money which Colin will get

[tex]6x = 6 \times 2 \\ = 12[/tex]

He will get £12

Hope this helps you.
