Answer:
Third step is incorrect. The correct factored form is (x-1)(2x-5).
Step-by-step explanation:
The given expression is

We need to find the factored form of this expression.
Step 1: Given

Step 2: Splitting the middle term method, the middle term can be written as (-5x-2x).


Step 3: Taking out common factors from each parenthesis.

Step 4: Taking out common factors.

Therefore, the third step is incorrect. The correct factored form is (x-1)(2x-5).
If you understand what is linear pair, you can see the same in triangle also. A linear pair is a pair of adjacent, supplementary angles. Adjacentmeans next to each other, and supplementary means that the measures of the two angles add up to equal 180 degrees.
Answer:
47.32 in^2
Step-by-step explanation:
Area rectangle = 21cm * 10.5cm = 220.5 cm^2
Area circle = pi*r^2
= Pi * 5.25^2
=( 86.59 in^2 )*2
= 173.18 in^2
Shaded region. 220.5 - 173.18 = 47.32 in^2
X-1%x^2-2x-3 =0
X-1=0
X=1 , ≠-1 , x≠3
Answer X=1
