What is the area of the triangle? 5 4 3 units?​

Mathematics
1 answer:
tankabanditka [31]2 years ago
4 0

Answer:

6 units squared

Step-by-step explanation:

Formula:

area = 0.25 * √( (a + b + c) * (-a + b + c) * (a - b + c) * (a + b - c) )

Assign variables:

A = 5, B = 4, C = 3.

Distribute:

area = 0.25 * √( (5 + 4 + 3) * (-5 + 4 + 3) * (5 - 4 + 3) * (5 + 4 - 3) )

Combine like terms

area = 0.25 * √( (12) * (2) * (4) * (6) )

Multiply:

area = 0.25 * √(576)

Square root:

area = 0.25 * 24

Multiply:

area = 6 units squared

Flura [38]

The <em><u>equation of a straight line</u></em> is an equation that comes in the form of an algebraic equation. It is also referred to as <u>Slope - Intercept form.</u> It can be represented using the equation below:

Equation : y = mx + c

where:

<u><em>m = Gradient</em></u>

<u><em>c = Slope of the line</em></u>

The equation that shows how the price of a personal pizza y, depends on the number of toppings x  is y = 7 + x

This question can be solved and represented using the equation of a straight line.

Let's represent

  • y = price of a personal pizza

  • x = number of toppings

  • The price for a plain cheese pizza = $7

  • The price for each of the toppings = $1

Therefore, the equation that shows how the price of a personal pizza y, depends on the number of toppings x  is written as:

y = $7 + $1 * x

y = 7 + x
