Answer:
Its 4
Hope this helps!
Step-by-step explanation:
Answer:
(x + 4)(x - 2) = x · x
(option L)
Step-by-step explanation:
we know that area = length × width
So, can write out the lengths and widths that we know:
(note: I will use the square as the reference point, because we can simply say "x" for both of its side lengths--you'll see why this is easier later)
Rug A:
length = x
width = x
Rug B:
length: x + 4
(4 feet greater than rug A length)
width: x - 2
(2 feet less than rug A width)
we can now set these areas to be equal to each other:
(rug A) = (rug B)
(length · width of A) = (length · width of B)
(x · x) = [ (x + 4)(x - 2) ]
So, the equation:
(x + 4)(x - 2) = x · x
can be used to find x (the length in feet) of rug A
hope this helps!! have a lovely day :)
Answer:
mean= 50
median = 40
mode 95
Step-by-step explanation:
Put the numbers in order from smallest to largest
7,12,13,40,88,95,95
The mean is adding up all the numbers and dividing by the number of numbers
(7+12+13+40+88+95+95)/7
350/7 = 50
The median is the middle number
7/2 = 3.5
Round up so the 4th number is the median
40 is the median
The mode is the most often which is 95 since is appears twice
B= 60
To find b you must do the pythagorean theorem because it is a right triangle
65^2 - 25^2=b^2
3600=b^2
60=b
x= 18
To find x you must know that a triangle is made up of 180 degrees.
x= 180-(72+90)
x=180-162
x=18

Answer:
m = -15/4
Step-by-step explanation:
Going from (-7, 14) to (8, 10), we see x increasing by 15 and y decreasing by 4. Thus the slope of the line through these two points is
m = rise/run = 15/(-4), or m = -15/4
