Answer:
1, 2, 3, 6
Step-by-step explanation:
This questions is asking the GCF of 42 and 90. To find them, we have to find all their factors.
<u>42</u> <u>90</u>
1, 42 1, 90
2, 21 2, 45
3, 14 3, 30
6, 7 5, 18
6, 15
9, 10
Now we find the numbers that match up.
They both share 1, 2, 3, and 6 thus this is our answer
Answer:
x = -3 +/- square root(22)
Step-by-step explanation:
x = -b +/- square root(b^2 - 4ac) / 2a
ax^2 + bx + c = 0
these are both the quadratic formula but one is solved for the x and another for 0
a= 1
b= 6
c = -13
x= -6 +/- square root( 6^2 - 4(1)(13)) / 2(1)
x = -6 +/- sqrt( 36 + 52) / 2
x= -6 +/- sqrt (88) / 2
sqrt of 88 = 2 x sqrt (22)
divide 2 on each
x= -3 +/- sqrt (22)
Factor: 27x^2y - 43xy^2
Factors of 27:
1(27), 3(9)
Factors of 43:
1(43) no common number between these two.
Factor x, and y, as they present, therefore, the numbers cannot be factored. stay as is.
Your answer is: xy(27x - 43y)
Hope that helps!!!
Let's look at what's happening to the x and y coordinates.
x1 is 1, and x2 is -1. The difference between them is 2. x is decreasing by 2. Therefore, the first part of our answer is x-2.
How, y1 is 3 and y2 is 4. This is increasing by 1.
So, our answer is (x-2,y+1)
