Answer:
Prime numbers are whole numbers that are greater than 1 which only have factors of 1 and itself.
The area of the triangle is 1358 square feet
Step-by-step explanation:
Area = 1/2 (base * height)
Area = 1/2 (56 * 48.5)
Area = 1/2 (2716)
Area = 1358
The general rule for difference of two squares is that when factorised it can be written in the form (a+b)(a-b) where a is the square root of the first part of the function and b is the square root of the second part of the function.
From this we can find the square root of x² to find a and the square root of 16y² to find b.
In this case √x²=x and √16y²=4y
Therefore fully factorised it can be written as (x+4y)(x-4y)
43% decrease and its spelled percent
