The perimeter is the sum of the lengths of the sides: 5 ft + 12 ft + 16 ft = 33 ft.
The area is found using the formula A = (1/2)(b)(h), where b = length of base and h = altitude. Here,
A = (1/2)(5 ft)(8 ft) = 20 ft^2
To find the slope(m), use the slope formula:
And plug in the two points
(3, -6) = (x₁, y₁)
(11, 0) = (x₂, y₂)
(two negative signs cancel each other out and become positive)
Simplify the fraction
When factoring, it's easier to "pick out" the GCF first because it makes it simpler to factor even further. Otherwise, you will be troubled with lots of numbers and variables, so it will just get confusing.
Answer:
Given, m = 3 and n = 4
5×3 + 4×4 – 3
15 + 16 - 3
31 - 3
