3/4n=-1 3/4n-18

Step by step please

Solving the expression we get

Step-by-step explanation:

We need to solve the expression:

Solving:

First we convert mixed fraction into improper fraction

Now adding 7/4 n on both sides

Now, taking LCM on left side

LCM of 4 and 4 is 4

Now, multiply both sides by 4/10

So, solving the expression we get

there are no figures how am i supposed to answer this question

step-by-step explanation:

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'.
