Step-by-step explanation:

Given:

Perimeter of an equilateral triangle = 54 cm

Find:

Area of equilateral triangle

Computation:

Perimeter of an equilateral triangle = 3 x Side

54 = 3 x Side

Side of equilateral triangle = 54 / 3

Side of equilateral triangle = 18 cm

Area of equilateral triangle = [√3/4]side²

Area of equilateral triangle = [√3/4][18]²

Area of equilateral triangle = [√3/4][324]

Area of equilateral triangle = [√3][81]

Area of equilateral triangle = 81√3 cm²

What is the product if a-3 and -2a^2+15a+6b2

Ierofanga [76]

The product if a-3 and -2a^2+15a+6b^2 is: $-2a^3+21a^2+6ab^2-45a-18b^2$

Step-by-step explanation:

In order to find the product of 2 expressions, distributive property can be used.

Given expressions are:

$a-3\\and\\-2a^2+15a+6b^2$

Product of given expressions

$= (a-3)(-2a^2+15a+6b^2)\\= a(-2a^2+15a+6b^2)-3(-2a^2+15a+6b^2)\\= -2a^3+15a^2+6ab^2+6a^2-45a-18b^2$

Combining like terms

$= -2a^3+15a^2+6a^2+6ab^2-45a-18b^2\\=-2a^3+21a^2+6ab^2-45a-18b^2$

Hence,

The product if a-3 and -2a^2+15a+6b^2 is: $-2a^3+21a^2+6ab^2-45a-18b^2$
