Mathematics
1 answer:
Alexus [3.1K]3 years ago

Answer:

Part a) (2m+7n)(2m-7n)

Part b) x^2-16xy+64y^2

Part c) 216a^3b^6

Part d)  (a^2-b^2)

Step-by-step explanation:

Part a) The difference of the squares of 2m and 7n.

we know that

The difference of the squares formula is equal to

(a^2-b^2)=(a+b)(a-b)

substitute

(2m)^2-(7n)^2=(2m+7n)(2m-7n)

Part b) The square of the difference of x and 8y

The formula of the square of the difference between two numbers is equal to

(a-b)^2=a^2-2ab+b^2

substitute

(x-8y)^2=x^2-2(x)(8y)+(8y)^2=x^2-16xy+64y^2

Part c) The tripled product of 6a and b^2

we have

(6ab^{2})(6ab^{2})(6ab^{2})=(6ab^{2})^3=(6^3)(a^3)(b^{2})^3=216a^3b^6

Part d) The product of the sum of a and b and their difference

The expression is equal to

(a+b)(a-b)

The expression represent the difference of the squares between a and b

so

(a+b)(a-b)=(a^2-b^2)

List the following fractions from least to greatest 1/6 2/3 1/2 1/3
lawyer [7]

Answer:

1/6 < 1/3 < 1/2 < 2/3

Step-by-step explanation:

We can turn the following to decimal;

1/6 = 0.16666666666        

2/3 = 0.66666666666

1/2 = 0.5

1/3 = 0.33333333333

0.16666666666   < 0.33333333333 < 0.5 < 0.66666666666

Thus, from least to greatest is 1/6 < 1/3 < 1/2 < 2/3
