yes

show me how to get the answer

Yes,

All multiples of an even number are themselves even.

4 is an even number, so its multiples are all even.

First you separate it into prime factors (start looking for small factors, such as 2, 3, 5). Then, you combine the factors with exponents.

A = pi r^(2)

pi = 3.14

r = 10

Substitute

A = 3.14 X 10^(2)

A = 3.14 X 100 cm^(2)_

A = 314.0 cm^(2)

'dm^(3)' is a measure of liquid volume.

'dm^(3( ' means decimetres cubed.

It is the same volume as litres.

1 dm^(3) = 1 litre.

It is used in chemistry labs. when completing volumetric analysis.

Let the number be 'm' & 'n'

m + n = 25

m - n = 1

Add the two eq'ns.

2m = 26

m = 26/2 = 13

Hence n = 12

its 4x +7.....since the 7 doesn't have an x like the 4 you can't add them together..:D

22

2x^(3) - 10x^(2) - 12x

'2' and 'x' are common factors , so take them out.

Hence

2x(x^(2) - 5x - 6)

Factor inside the brackets .

2x(x - 6)(x + 1)

Done !!!!

x^(3) - x^(2) - 12x

'x' is a common fractor ' tsker it out.

Hence

x(x^(2) - x - 12)

Factor inside the brackets /

x(x - 4(x + 3)

Done!!!!!

The inverse of 23 depends on what type of inverse you mean:

• Multiplicative inverse (reciprocal): \(\frac{1}{23}\)

• Additive inverse: \(-23\)

Usually, when asked for the inverse of a number in mathematics, the answer is its reciprocal: \(\boxed{\frac{1}{23}}\).

1sr find the EXTerior Angle. 4

EXT ANG = 360 / 50

EXT Ang = 36/5 = 7.2

Hence

Int Ang = 180 - 7.2 = 172.8.

Since there are 50 sides there are 50 interior angles. at 172.8 each

So sum of interior angles is 50 X 172.8 = 8640 degrees.

NB

Remember the table.

Sum of interior angles.

3 sides = 180

4 sides= 360

5 sides = 540

et seq/

For each additional side add 180 degrees.

You have answered the question for yourself!!!! --- '50'.

2x + 3x = 5x

-2x + 3y = -7

3x + y = 16

simultaneous equations.

Elimination a letter. Arbitrarily select 'y'

Hence multiply the bottom eq'n by ' -3'

Hence

-2x + 3y = -7

-9x - 3y = -48

Add the eq'ns/

-11x = =55

x = -55/-11 = 5

When x = 5 , substitute into either eq'n for 'y'

-2(5) + 3y = -7

-10 + 3y = -7

3y = 3

y = 1

Hence answer in ( x,y) fpr, is ( 5,1).

3x + y = 5

There is no answer for 'x' ^ 'y' as there are two unknowns, and no comparable values.

However. it is a linear equation, and can be rearranged into the straight line form .

y = -3x + 5

Hence

Gradient/slope is '-3' and the y0intercept is '5'.

p = 2s + 5

Subtract '5' from both sides

2s = p - 5

Divide both sides by '2'

s = [p - 5] / 2

p + 2 = 2 - 3p

Subtract '2' from both sides

p = -30

Subtract 'p' from both sides

0 = -2p

Hence 2p = 0

It folllows p = o
