Area of triangle=1/2×base×height
861cm^2=1/2×81×height
861=41× height
height=861/41
Height=21cm
so height of triangle is 21cm
False,<span>The opposite is true: the GCF of an odd number and an even number is always odd.
All the factors of an odd number are odd; or to put it another way: If a number has an even factor, the number itself must be even.
Thus the only common factors between odd and even numbers must be odd.

Your answer is the second statement, Angle D is an exterior angle because it is not inside the triangle. This is because exterior angles on any shape are angles that are not included in the shape, but are rather attached on the outside. I hope this helps!
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
