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:
(10x+4x^2+13)
Step-by-step explanation: 10 and 3 do not have a variable therefore they go together (both being positive you add). 2x, 2x, and 6x have the same variable, being positive you add. 4x^2 is the only number with the x^2 variable and stays by itself due to no others.
Answer:
<em>$1.50</em>
Step-by-step explanation:
Given the total weekly pay of Hector modeled by the equation;
y = 10(8.5 + x)
We are to find the amount of Hector's raise per hour x given the total oay y = $100
Substitute y = 100 into the equation and find x as shown;
y = 10(8.5 + x)
100 = 10(8.5+x)
100/10 = 8.5 + x
10 = 8.5 + x
x = 10 - 8.5
<em>x = 1.5</em>
<em>Hence the amount of Hector's raise per hour is $1.50</em>
Responder:
Aproximadamente 13,4 unidades.
