Answer:

=2x^2+3xy-2y^2

Step-by-step explanation:

When given the following problem;

(2x-y)(x+2y)

Distribute, multiply every number in one of the parenthesis by every number in the other;

(2x-y)(x+2y)\\=(2x)(x)+(2x)(2y)+(-y)(x)+(2y)(-y)

Simplify,

=(2x)(x)+(2x)(2y)+(-y)(x)+(2y)(-y)\\=2x^2+4xy-xy-2y^2\\=2x^2+3xy-2y^2

Therefore, the final answer is;

=2x^2+3xy-2y^2

Answer:

The Scarecrow got it wrong.

Step-by-step explanation:

1. The Pythagoras theorem does not apply to every isosceles triangle. It only applies to a triangle that has one of its sides as a right angle i.e. 90 degrees.

2. The Pythagoras theorem deals with squares of sides not square roots of sides.

3. Pythagoras theorem does not state that the square of any side is equal to the sum of the remaining two. Instead, it states that the square of the hypotenuse of a right angled triangle is equal to the sum of the square of the remaining two sides.

4. The Pythagoras theorem does not mention anything about an isosceles triangle. It deals only with Right angled triangles.

Is the product of -5 +x and x+4 equal to the product of 5+x and x-4? Explain your answer.
beks73 [17]

Let's find out!

-5 + x * x + 4.

-5 + x^2 + 4.

-5 + 4 + x^2.

-1 + x^2.

5 + x * x - 4.

5 + x^2 - 4.

5 - 4 + x^2.

1 + x^2

So, they are NOT the same, because one of the "1"'s are negative, and the other is positive.
