x^2 - 10x + 21 / x^2 -6x -7

Step-by-step explanation:

Given

← factorise numerator/ denominator

x² - 10x + 21 = (x - 7)(x - 3)

x² - 6x - 7 = (x - 7)(x + 1)

The expression can be written as

= ← cancel the common factor (x - 7) on numerator/denominator

=

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
