Ted's error is that he did not follow proper order of operations... PEMDAS stands for the order in which you approach all problems in math... Parentheses, exponents, multiplication, division, addition, then subtraction.

Ted multiplied the exponents first instead of completing the operations inside the parentheses. The result was that the sign of his base is incorrect. Here is how it should have gone...

What is the factor form of x^2-9x+14

Answers

x^2-9x+14 =x^2-2x-7x+14=x(x-2)-7(x-2)=(x-7)(x-2)

Answer:

(x - 7)(x - 2)

Step-by-step explanation:

Consider the factors of the constant term (+ 14) which sum to give the coefficient of the x- term (- 9)

The factors are - 7 and - 2, since

- 7 × - 2 = + 14 and - 7 - 2 = - 9, hence

x² - 9x + 14 = (x - 7)(x - 2) ← in factored form

A garden contains 20 different species of plants. Five of these plants are ferns. What percent of the garden is made up if ferns?

Answers

Answer:

25%

Step-by-step explanation:

A garden contains 20 different species of plants. Five of these plants are ferns.

Total number of species = 20

In that 20 species , 5 are ferns

WE need to find out how much percentage of 20 is 5

LEts make an equation. x be the percentage

x% of 20 is 5

(x)/(100) \cdot 20 = 5

(x)/(5)= 5

Now multiply both sides by 5

x= 25

So 25% of 20 species plans is equal to 5 ferns
5 out of 20 plants can be written as 5/20.  

A percentage is just a fraction with the denominator being 100.  
100 / 20 = 5. 
5 X 5 = 25
25/100

25% of the garden is made up of ferns
