h(t)=- 16t^2 +16t+12 zeros of the parabola

Answers

Step-by-step explanation:

h(t) = -16t² + 16t + 12

h(t) = -4(4t² - 4t - 3)

h(t) = -4(2t - 3)(2t + 1)

When h(t) = 0, we have t = 1.5 or t = -0.5.

Hence the zeroes are 1.5 and -0.5.

The side length of an equilateral triangle is 6x - 12. Write an expression for the perimeter of the triangle in simplest form.

Answers

Answer:

18x - 36

Step-by-step explanation:

In an equilateral triangle the 3 sides are congruent, then

perimeter = 6x - 12 + 6x - 12 + 6x - 12 ← collect like terms

                = 18x - 36

The required expression would be 18x - 36 for the perimeter of the triangle in simplest form.

What is the perimeter of a triangle?

The perimeter of a triangle is defined as the addition of the lengths of the triangle's three sides.

What are Arithmetic operations?

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operations is called the arithmetic operator.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

As we know in an equilateral triangle the 3 sides are congruent.

The perimeter of the triangle = 6x - 12 + 6x - 12 + 6x - 12

Combine the likewise terms and we get

The perimeter of the triangle =  18x - 36

Therefore, the required expression would be 18x - 36 for the perimeter of the triangle in simplest form.
