Which one of the following expressions will find the sum of interior angles of a polygon with 14 sides?

cupoosta [38]

To find the total measure of the angles in a polygon, the formula is 180(n-2) n being the number of sides in the polygon.

So the correct answer is B) 180(14-2)

Thats my question down there mates

Law Incorporation [45]

Answer:

x = 9

Step-by-step explanation:

A line segment parallel to a side of a triangle and intersecting the other 2 sides divides the 2 sides in proportion, that is

$\frac{9}{72}$ = $\frac{1}{8}$ = $\frac{3x-20}{56}$ ( cross- multiply )

8(3x - 20) = 56

24x - 160 = 56 ( add 160 to both sides )

24x = 216 ( divide both sides by 24 )

x = 9

zlopas [31]

<span>d. y = 15x 900</span>

Although you do not give the rates I assume the answer is D as it is the only positive multiplication. You cannot have negative height.

Expand the polynomial and simplify: (4xy− 1 8 y^2)^2

Vinvika [58]

Answer: $4y^{2}(2x-9y)^{2}$

Step-by-step explanation:

We have the following polynomial:

$(4xy-18y^{2})^{2}$

This is a polynomial of the form $(a-b)^{2}=a^{2}-2ab+b^{2}$ . Following this rule to expand it, we have:

$(4xy)^{2}-2(4xy)(18y^{2})+(18y^{2})^{2}$

$16x^{2}y^{2}-144xy^{3}+324y^{4}$

Applying common factor $4y^{2}$ :

$4y^{2}(4x^{2}-36xy+81y^{2})$

Note the polynomial inside the parenthesis is a perfect square trinomial, which can be factored to $(2x-9y)^{2}$ . Hence, the final simplification is:

$4y^{2}(2x-9y)^{2}$

Change the units up above to the correct answer from (a) to (d)

Leto [7]

Answer:

Step-by-step explanation:

1 cm = 10 mm

a) 0.1 cm = 1 mm

1 mm = 1000 m

b) 25000mm = 25 m

1 g = 0.001 kg

c) 7g = 0.007 kg

1ml = 0.000001

d) 30000ml = 0.03 kl
