a number of park tickets are purchased online. Each ticket costs $25 and it costs $8 to ship the entire order. Write an expression to represent the total cost for t tickets. Then find the total cost if 12 tickets are purchased

25x + 8 = t 25(12) + 8 = 308

Step-by-step explanation:

x = amount of tickets

t = total cost

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'.
