8 (2k-7)- 4 (k+5)

Is 12k-76 the answer?

Yes, 12k - 76 is the answer.

Step-by-step explanation:

Expanding:

16k - 56 - 4k - 20

Simplifying:

12k - 76

no because your going to multiply 8 by 2k to get 16k and same with the other side so it would be -4k

-4k+16k is 12k and you do the same with the numbers 8 X -7 = -56

-4 X -5 = positive 20 so the anwser is

16k-36

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'.
