Answer: (3x + 11y)^2
Demonstration:
The polynomial is a perfect square trinomial, because:
1) √ [9x^2] = 3x
2) √121y^2] = 11y
3) 66xy = 2 *(3x)(11y)
Then it is factored as a square binomial, being the factored expression:
[ 3x + 11y]^2
Now you can verify working backwar, i.e expanding the parenthesis.
Remember that the expansion of a square binomial is:
- square of the first term => (3x)^2 = 9x^2
- double product of first term times second term =>2 (3x)(11y) = 66xy
- square of the second term => (11y)^2 = 121y^2
=> [3x + 11y]^2 = 9x^2 + 66xy + 121y^2, which is the original polynomial.
Answer:
Loss %age = 25%
Step-by-step explanation:
<u><em>Cost Price of Item</em></u> = 250,000/-
<u><em>Loss </em></u>= 1/4 = 0.25 of 250,000
=> 62,500 /-
<u><em>%age Loss</em></u> = 
=> 62,500 * 100 / 250,000
=> 6,250,000/250,000
=> 25 %
Answer:
x=2, y=1. (2, 1).
Step-by-step explanation:
y=3x-5
6x+3y=15
-----------------
6x+3(3x-5)=15
6x+9x-15=15
15x-15=15
15x=15+15
15x=30
x=30/15
x=2
y=3(2)-5=6-5=1
This is an inappropriate conclusion because of <u>D. At 10 months</u>, ninety percent of toddlers have not reached the developmental milestones to walk.
<h3>What is an inappropriate conclusion?</h3>
An inappropriate conclusion is one arrived at without a proper research design. An inappropriate conclusion can also be reached when the interpretation of the research result is not based on the findings.
Our conclusion implies that there is a wrong interpretation of the research findings because of the researcher's bias.
Thus, the research conclusion is <u>inappropriate</u> because of Option D.
