The length of a rectangle is 13 meters more than its width. The area of the rectangle is 48 square meters. Determine the length and width of the rectangle. (solve algebraically)
Answers
Answer: The length is 16 meters and the width is 3 meters.
Step-by-step explanation:
Since we know the length and w, we will represent the length by l and the width by w.
We know the length is 13 more than the width so we will represent it by the equation l = w + 13 .
The width will be represented by w.
We know the area of a rectangle is the length being multiplied by the width.
Since we know the area, multiply the length by the width and set it equal the area and solve for w.
w(w+ 13) = 48 Multiply on the left side
w^2 + 13w = 48 subtract 48 from both sides
-48 -48
w^2 + 13w - 48 = 0 Now find two numbers that their product is -48 and their sum 13.
The numbers 16 and -3 works, because 16* -3 = -48 and 16 + (-3) = 13.
Rewrite the whole equation in this form.
w^2 + 16w -3w - 48 = 0 Now factor on the left side.
w(w + 16) -3(w+16) = 0 Factor out w+16
(w+16)( w-3) = 0 Now set each of the expressions to equal to 0 and solve for w.
w+ 16 = 0 or w-3 = 0
-16 -16 +3 +3
w = -16 or w = 3
-16 can't be use to represent distance so w has to equal 3 and this means the width is 3.
The length is 13 meters more than the width so 3 + 13 will be the width.
l = 3 + 13
l = 16

Answer:
870,722
Step-by-step explanation:
Answer:
870,000
Step-by-step explanation:
When rounding lets take this problem as an example, you need to rely on the number that is right from it. In this case, it will be the number 3. Any number that is below 4 will be 870,000, any number that is above a 5 will be 880,000. Also note that rounding is always going to be 1-10 not 1-5. What I mean is people will do the mistake and say 873,711 will be rounded to 875,000 which is incorrect.

which Equation represents on the passes through (-2,4) and has a slope of 2/5
y-4=2/5(x-2)
y+4=2/5 2/5(x-4)
y+2=2/5(x-4)
y-2=2/5 1/3(x+4)
Answers
Step-by-step explanation:
Hey there!
The given point is (-2,4) and slope is 2/5.
While finding the eqaution which has slope and point always use one point formula.
(y-y1) = m(x-x1)
Keep all values.
(y - 4) = 2/5(X+2)
Therefore, the equation is (y-4) = 2/5(X+2).

Answer:
(x, y) = (7, 2)
Step-by-step explanation:
We assume you want the solution to this system of equations.
Since you're seeking help from "technology", it is appropriate to use the technology of a graphing calculator to find the solution. The attachment shows it to be (x, y) = (7, 2).
__
The coefficient of x in the first equation is 1, so it is convenient to use that equation to write an expression for x:
x = 4y -1 . . . . . add 4y to the equation
3(4y -1) +5y = 31 . . . . substitute for x in the second equation.
17y = 34 . . . . . . . . . . . simplify, add 3
y = 2 . . . . . . . . divide by 17
x = 4(2) -1 = 7 . . . . use the equation above to find x
The solution is (x, y) = (7, 2).
