Your friend factors the expression 48x-16. is your friend correct? explain your reasoning.

16(3x - 1)

Step-by-step explanation:

the greatest common factor of 48 and 16 is 16, hence

48x - 16 = 16(3x - 1)

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'.

so, converting firstly the mixed fractions to improper fractions and then "adding".
