Bethany sells roses and petunias. The expression 3r+2.5p gives the cost (in dollars) of roses(r) and petunias(p). What is the cost of 2 roses and 4 petunias?

Total cost = 16

Step-by-step explanation:

In the equation of cost, we can see that each rose costs 3 and each petunia costs 2.5.

To find the total cost of two roses and four petunias, we can use the values r = 2 and p = 4 in the equation given, so:

Total cost = 3r + 2.5p = 3*2 + 2.5*4 = 6 + 10 = 16

So the total cost of two roses and four petunias is 16.

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'.
