Answer:
7(3x-2)
Step-by-step explanation:
you can factor it down with GCF ( Greatest common factor)
Answer:
Pr(blue) = 1/2, Pr(white) = 1/6, Pr(red) = 1/3
Step-by-step explanation:
1 white,
3 blue, and
2 red marbles
Total marbles = 1+ 3 + 2 =6
Probability of picking blue = number of blue ➗ total number of marbles
Pr(blue) = 3/6
Divide both by 3 to make the fraction to the lowest term.
Pr(blue) = 1/2
Probability of picking white = number of white ➗ total number of marbles
Pr(white) = 1/6
Probability of picking red = number of red ➗ total number of marbles
Pr(red) = 2/6
Divide both by 2 to make the fraction to the lowest term.
Pr(red) = 1/3

Increase $110,000 by 20% 3 times.
110,000 x 0.2 = 22000
(0.2 is 20% as a decimal, we needed to convert it to multiply it)
So we must add 22000 to 110,000, then take 20% of the new cost, and repeat.
Add them
110,000 + 22000 = 132000
Take 20% of new value
132000 x 0.2 = 26400
Add that
132000 + 26400 = 158400
Take another 20% of that
31680
Add them
158400 + 31680 = 190080
So the value is now $190,080
A much more efficient way to do this would be multiplying 1.2 instead of 0.2, and skipping the adding part, as you already took 100% of it and are adding 20% more.
Hope this helps!
Answer:
and
Step-by-step explanation:
Given a polynomial with rational coefficients, its irrational and complex roots would occur in conjugate pairs.
For example, if the roots of a polynomial are 2 + , 3 and 4 - 3i, then 2 - , and 4 + 3i are also roots of the polynomial.
Therefore, since the given polynomial has rational coefficients and some of its roots are , and - , then - and are also roots of the polynomial.
Answer:
The length of XY is 17
Step-by-step explanation:
Given that X is midpoint of line WY
WX=3x-1
WY=10x-26
To find XY:
Given WY is straight line and X is midpoint of line WY
We can write as
WX+XY=WY
(3x-1)+XY=(10x-26)
XY=7x-25
Also, WX=XY
(3x-1)=(7x-25)
-1+25=7x-3x
4x=24
x=6
The length of XY is 7x-25=7(6)-25=42-25=17
