Write as an expression and simplify

Alexus [3.1K]

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

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

What are three equivalent expressions for 3x+3(x+y)

Cloud [144]

3 x + 3 (x + y)

3 (2 x + y)

6 x + 3 y

y = -2 x

y = -2 x (3 (x + y) + 3 x) = 6

(3 (x + y) + 3 x) = 3

(3 x + 3 (x + y)) dx = 3 (x^2 + x y) +

(x^2 + y^2<R^2)(3 (x + y) + 3 x) dx dy = 0

(3 x + 3 (x + y)) dy dx = 0

Step-by-step explanation:

Hope this helps ツ
