We have been provided :-
- Length of a side of a square =
We know that,
Therefore, to find the area we will simply put the given values in the equation.
So,
<u>❆ Some important identities to remember</u> :-
Hope that helps :)
Answer:
The factors of x² - 3·x - 18, are;
(x - 6), (x + 3)
Step-by-step explanation:
The given quadratic expression is presented as follows;
x² - 3·x - 18
To factorize the given expression, we look for two numbers, which are the constant terms in the factors, such that the sum of the numbers is -3, while the product of the numbers is -18
By examination, we have the numbers -6, and 3, which gives;
-6 + 3 = -3
-6 × 3 = -18
Therefore, we can write;
x² - 3·x - 18 = (x - 6) × (x + 3)
Which gives;
(x - 6) × (x + 3) = x² + 3·x - 6·x - 18 = x² - 3·x - 18
Therefore, the factors of the expression, x² - 3·x - 18, are (x - 6) and (x + 3)
Step-by-step explanation:
1/3-6
Lcm=3
(1-18)/3
-17/3
-5 2/3
" the sum " means add
(c + d) - 3 <== ur expression
B. if two lines are perpendicular, then they intersect to form four right angles.
