Answer:
value of x is B 5.5
Step-by-step explanation:
B 5.5 value of X
M=(y2-y1)/(x2-x1)
(x1,y1)=(-3,3) and (x2,y2)=(5,9)
m=(9-3)/(5-(-3))
m=6/8
m=3/4
Answer: Length = 24; width =4
Step-by-step explanation
Since the ratio of the length to width is 6:1
Let the length be represented as 6x
And the width be = x
Such that that the Perimeter of the rectangle which is
Perimeter = 2(length + width) becomes
56 = 2(6x + x)
56/2 = 6x+x
28 = 7x
x = 4
Width = 4
Length = 6x= 6 x 4 = 24
No it's a number that can be found in both of the factor lists.
Hi there!
We are given the equation 20 + 6c - 2c², and are told to factor it. Well, to do this, we can first rearrange the terms in decreasing order: -2c² + 6c + 20. Next, we see that we can take out a common factor -2 from the whole equation. This gives us -2(c² - 3c - 10). Now, we take the constant term, -10, and we find all it's factors.
-1 10
-10 1
-5 2
-2 5
Now, find the sums of the factors.
-1 + 10 = 9
-10 + 1 = -9
-5 + 2 = -3
-2 + 5 = 3
We see that the only pair of factors that add up to -3 are -5 and 2. Now, we can factor the whole equation to -2(c + 2)(c - 5). Hope this helped!
