Which of the following is not a valid way of starting the process of factoring60x² +84x +49?Choose the inappropriate beginning below. O A. (x )(60)OB. (2x (30%)O C. (6x X10x)OD. (2x (5x )

Given the equation:

60x^2 + 84x + 49

We are to determine among the options which is not a process of factorizing.

In factorizing, you get factors of the given numbers of the equation that when they are being multiplied or added, they give the numbers in the equation.

So, looking at the options, the only option that does not satisfies the requirement for starting a factorization process is B, which is (2x (30%)

Therefore, the inappropriate process of starting factorization among the option is option B which is (2x (30%).

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
