creativ13 [48]

Answer: The answer is true.

Step-by-step explanation:  The given statement is :

" The area of a regular heptagon can be found by breaking the heptagon into seven congruent triangles and then taking the sum of their areas".

We are to check its is true or false.

In the attached figure, a regular heptagon ABCDEFG is drawn. Sine the heptagon is regular, so all its sides are equal and all its angles are also equal. So, we can break the heptagon into seven congruent triangles 1, 2, 3, 4, 5, 6 and 7 taking 'O' as the centre of the heptagon.

Finding the areas of these seven triangles and taking the sum will result in the area of the heptagon ABCDEFG.

Thus, the given statement is "TRUE".

x = 3,-1, multiplicity of 2.

Therefore, it is 4-degree polynomials. (considering that x = 3,-1,2,2)

We just convert these x-values into x-intercept form and convert again in standard form by multiplying.

(x-3)(x+1)(x-2)²

(x²-2x-3)(x²-4x+4)

(x⁴-4x³+4x²-2x³+8x²-8x-3x²+12x-12)

Thus the answer is x⁴-6x³+9x²+4x-12
