Explane how you can tell 4 is a factor of 30

Answers

Answer 1

Answer: That is very difficult, since 4 is not a factor of 30. The prime factorization of 30 is 2*3*5. There is no combination of these numbers that results in 4, so it is not a factor of 30.

Answer 2

Answer: Just count. 4 8 12 16 20 24 28 32 oop we past 30 so 4 is not a factor of 30.

A sign in a store window has the shape of a regular nonagon (9-sided figure). The sign has an apothem length of 40 cm and a side length of 29 cm.What is its area?

____cm2

Answers

Area = A
Side length = L = 29 cm
number of sides = n = 9
Apothen = a = 40 cm

A = nLa / 2 = 9*29cm*40cm / 2 = 5,220 cm^2

Answer: 5,220 cm^2

Answer:

5220 cm

Step-by-step explanation:

A=9/4(a^2)cot(180°/9) is the formula and got 5,220 cm

Part B: Factor x2 + 8x + 16. Show your work. (3 points)

Part C: Factor x2 − 16. Show your work. (3 points)

Answers

Answer: The factorization of all the parts are :

Part A : $x^2y^2+6xy^2+8y^2=y^2(x+2)(x+4).$

Part B : $x^2+8x+16=(x+4)(x+4).$

Part C : $x^2-16=(x+4)(x-4).$

Step-by-step explanation: We are given to factorize the following quadratic polynomials :

Part A : Factor x²y² + 6xy² + 8y².

Part B : Factor x² + 8x + 16.

Part C: Factor x² − 16.

We will be using the following factorization formulas :

$(i)~x^2+ax+bx+ab=(x+a)(x+b),\n\n(ii)~x^2+2xa+a^2=(x+a)^2=(x+a)(x+a),\n\n(iii)~x^2-a^2=(x+a)(x-a).$

The factorization of all the parts area as follows :

Part A :

We have

$x^2y^2+6xy^2+8y^2\n\n=y^2(x^2+6x+8)\n\n=y^2(x^2+4x+2x+8)\n\n=y^2(x(x+4)+2(x+4))\n\n=y^2(x+2)(x+4).$

So, $x^2y^2+6xy^2+8y^2=y^2(x+2)(x+4).$

Part B :

We have

$x^2+8x+16\n\n=x^2+2* x*4+4^2\n\n=(x+4)^2\n\n=(x+4)(x+4).$

So, $x^2+8x+16=(x+4)(x+4).$

Part C :

We have

$x^2-16\n\n=x^2-4^2\n\n=(x+4)(x-4).$

So, $x^2-16=(x+4)(x-4).$

Thus, all the parts are factorized.
