Step-by-step explanation:
by using formula (a+b)^2=a^2+2ab+b^2
in these two we have to just open the formula
(3x+2y)^2
=(3x)^2+2(3x)(2y)+(2y)^2
=9x^2+12xy+4y^2
(3y+2x)^2
=(3y)^2+2(3y)(2x)+(2x)^2
=9y^2+12xy+4x^2

How to solve X²-X-42uing
using Fertoning Polynomials
Answers
Answer:
x = - 6, x = 7
Step-by-step explanation:
Begin by equating to zero
x² - x - 42 = 0
Consider the factors of the constant term (- 42) which sum to give the coefficient of the x- term (- 1)
The factors are - 7 and + 6 , since
- 7 × + 6 = - 42 and - 7 + 6 = - 1 , then
(x - 7)(x + 6) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 6 = 0 ⇒ x = - 6
x - 7 = 0 ⇒ x = 7

10x + 25y = 255 ___(1)
25x + 10y = 270 ___(2)
From (1)
10x = 255 - 25y
x = (255 - 25y) / 10
x = 25.5 - 2.5y
Put x = 25.5 - 2.5y in (2)
25(25.5 - 2.5y) + 10y = 270
637.5 - 62.5y + 10y = 270
-52.5y = - 367.5
y = 367.5 / 52.5
y = 7
x = 25.5 - 2.5(7)
x = 25.5 - 17.5
x = 8
Fantasy 5 lottery game is picking 5 numbers from 1-41. If you match them all you win the jackpot. What is the probability you win the jackpot?
Answers
Answer:
1 / 89927760
Step-by-step explanation:
Recall :
Probability = required outcome / Total possible outcomes
To pick five number for a lottery from the range (1 - 41) ;
For this scenario, selection will be done without replacement
To win lottery , all 5 selections must be matched
P(1st pick) = 1 / 41
P(2nd pick) = 1 /40
P(3rd pick) = 1/39
P(4th pick) = 1/38
P(5th pick) = 1/37
(1/41 * 1/40 * 1/39 * 1/38 * 1/37) = 1 / 89927760
Hence, Probability of winning lottery = 1 / 89927760

What’s 300(6+20)-120?
Answers
Answer: 7680
Step-by-step explanation:
Answer:
7,680
Step-by-step explanation:
Okay, so we use PEMDAS right, so we start with the parenthesis:
6 + 20 = 26
300 x 26 = 7,800
7,800 - 120 = 7,680
So 300(6+20)-120=7,680

If the loss incurred on selling an article is 7/20 of the cost price, then find the loss percentage.
Answers
Answer: The loss percentage = 65%
Step-by-step explanation:
Let x be the cost price.
As per given,
Selling price = [tex]\dfrac{7}{20}x[/tex]
Loss =Cost price - Selling price
[tex]=x-\dfrac{7}{20}x\\\\=\dfrac{20-7}{20}x\\\\=\dfrac{13}{20}x[/tex]
The loss percent = [tex]\dfrac{loss}{Cost\ price}\times100[/tex]
[tex]=\dfrac{\dfrac{13}{20}x}{x}\times100\\\\=\dfrac{13}{20}\times100\\\\=13\times5\%\\\\=65\%[/tex]
Hence, the loss percentage = 65%

What is the slope of (10,3) and (2,3)
Answers
Answer:
m=0
Step-by-step explanation:
the formula given for slope (m) calculated from two points is given as (y2-y1)/(x2-x1)
we are given the points (10,3) and (2,3)
label the values of the points to use for the formula:
x1=10
y1=3
x2=2
y2=3
plug into the formula
m=(3-3)/(2-10)
subtract
m=0/-8
divide
m=0
therefore, the slope is 0
Hope this helps! :D
0/-8

Answer:
A or [tex]\frac{\sqrt{6} }{2}[/tex]
Step-by-step explanation:
*note- this method only works because the denominator values are being multiplied, if they were being added then there are extra steps to keep in mind but for now this is simple*
Start by dividing the root 12 in the numerator by the root 2 in the denominator
[tex]\frac{\sqrt{12} }{\sqrt{2} }=\sqrt{6}[/tex]
Then we simply substitute back in the 2 (from the denominator) that we ignored for a second to get our answer
[tex]\frac{\sqrt{6} }{2}[/tex]
*note- if you are allowed to use a calculator then you could also plug in your values to check each answer option but since this question isn't too complicated there should be no need to do so unless you forget how to solve it algebraically*
