Answer:9x^4

Step-by-step explanation:

6x^4*3x^3 can be simplified to 18x^7 by separating out cand combining like terms  [6*3 = 18] and [x^4*x^3 = x^7]

This results in 18x^7 fr the top term

Do the same for the bottom term:  2x^2*x = 2x^3

We can now write:  (18x^7)/(2x^3)

The reduces to 9x^4

Answer:

(m+n)(m-n)

Step-by-step explanation:

formula: x^2 - y^2 = (x+y)(x-y)

add m and n to x and y to get

m^2 - n^2

then the formula says insert the m and n into the formula answer of (x+y)(x-y) to get our answer of

(m+n)(m-n)

Step-by-step explanation:

Answer:

if it is a right angle triangle then;

step 1   Determine if hypotenuse or side

step 2 calculate a^2+b^2 = c^2  or c^2-b^2 = a^2 if not given hypotenuse.

if it is an obtuse or scalene triangle then

step 1.  Determine the triangle third length we use trigonometry as cos (side a/sideb) to determines the angle between a and b.

With such angle for opposite side we can use sin (angle) x side to find hypotenuse or sin(angle) x hypotenuse to find side.

Answer:

-1.2; -0.67; -2/5; 1/2; 0.54

Step-by-step explanation:

because there are negative numbers, we put those first. the bigger the number behind the negative is, the smaller it is

-1.2 is the only negative with a ones place so it goes first

-0.67 comes right before -2/5, or -0.4

then we move into the positive numbers: 1/2 and 0.54

1/2 is 0.5, which is less than 0.54

so the order is -1.2; -0.67; -2/5; 1/2; 0.54

Answer:

6

Step-by-step explanation:

Given that f(3), x=3.

Since f(x) = 2x, we plug in 3 for x, and get 2 times 3. Therefore, the answer comes out to 6.

When f(3)

Then we have:

3=2x

Now we divide by 2 (on both sides)

and are left with

x = 1.5

Answer:

$3589.60

Step-by-step explanation:

Salary per fortnight {52 weeks in a year; 2 weeks in a fortnight}

= 86840 / 52 × 2

= 3340

Allowance per fortnight = 124.80 × 2 = 249.60

Therefore, total fortnightly pay is:

3340 + 249.60 = 3589.60

Answer:

The numbers are:

5, 12 and 4

Step-by-step explanation:

a + b + c = 21       Eq. 1

b = 2a +2             Eq. 2

b = 3c                   Eq. 3

From Eq. 2:

b - 2 = 2a

(b-2)/2 = a              Eq. 4

From Eq. 3:

c = b/3                     Eq. 5

Replacing Eq. 4 and Eq. 5 in Eq. 1:

(b-2)/2 + b + b/3 = 21

3(b-2)/6 + 6b/6 + 2b/6 = 126/6

3(b-2) + 6b + 2b = 126

(3*b + 3*-2) + 8b = 126

3b - 6 + 8b = 126

11b = 126 + 6

11b = 132

b = 132/11

b = 12

from Eq. 4

(b-2)/2 = a

(12-2)/2 = a

10/2 = a

a = 5

from Eq. 5

c = b/3

c = 12/3

c = 4

Check:

from Eq. 1

a + b + c = 21

5 + 12 + 4 = 21

Answer:

b

Answer:

to find range of interquartile sets of data

you see 5 vertical lines 1 is start point 2 is start of 2nd quartile 3 is start of 3rd quartile and also represents the median.  the 4th start of 4th quartile and 5th is very end point.

Therefore the interquartile is from start line 2 to start line 4

apply to each by if it says 10 and 34 then we show workjings 34-10 = 24 and that is the range once we deduct data from each other.

Therefore full range is start line 1 to end line 5

if this says 2 to 45 then full range is 45-2 = 43 and apply to each boxplot.

Step-by-step explanation:

Net pay for the individual is $132.83

Given that;

Number of hour worked = 27.25

Per hour pay = $5.95

Federal tax deduction = $13.29

Social Security deduction = $9.65

Other deductions = $6.37

Find:

Net pay

Computation:

Net pay = [(27.25)(5.95)] - 13.29 - 9.65 - 6.37

Net pay = [(27.25)(5.95)] - 13.29 - 9.65 - 6.37

Net pay = 162.1375 - 29.31

Net pay = 132.8275

Net pay = $132.83
