work the area of a rectangle out but already knowing the area and needing to know the length as it is two centermeters more than the width, area being 469

Answers

the area of a rectangle is the length times width:
a = l*w
the length is 2 centimeters more than the width:
l = w + 2
express area in terms of width
a = l*w
a = (w + 2)w
a = w^2 + 2w
w^2 + 2w = 469
w^2 + 2w - 469 = 0
we can solve using the general quadratic formula:
w = (-2 +- √(4 + 1876))/2
w = (-2 +- 43.36)/2
we use the positive solution:
w = (-2 + 43.36)/2
w = 20.68
thus the width is 20.68 cm
l = w + 2 = 20.68 + 2
l = 22.68
and the length is 22.68 cm

Answer:

$(-√(65) - 3 )/(4), (√(65) + 3)/(4)$

Step-by-step explanation:

Since we cannot factor the expression, we must use quadratic formula: $x = (-b +/-√(b^2 - 4ac) )/(2a)$

Plug in a for 2, b for 3, and c for -7 and you should find your roots.

Solve 4x = 16 for x.
x =

Answers

Well what ever you do to one side, you do to the other.
Your goal is to get the x alone
in order to do that we divide both sides by 4
4x = 16
÷4 = ÷4 The left side cancels out and the right side gets solved
********* because 16 ÷ 4 = 4 :)
x = 4

And there's your answer
x = 4

When in doubt, eat a pineapple :)

Just divide both sides by 4.

4x / 4 = 16 / 4

x = 4

2x-7y=16, 3y=7-x solve by elimination

Answers

Answer:

To solve the system of equations using elimination, we need to eliminate one variable by adding or subtracting the equations. Let's start by rearranging the first equation in standard form:

2x - 7y = 16

Next, let's rearrange the second equation so that both equations have the same number of x or y terms:

3y = 7 - x

We can rewrite this equation as:

x + 3y = 7

Now we have the following system of equations:

2x - 7y = 16

x + 3y = 7

To eliminate the y variable, we can multiply the second equation by 7:

7(x + 3y) = 7(7)

This gives us:

7x + 21y = 49

Now we can subtract the first equation from this equation:

(7x + 21y) - (2x - 7y) = 49 - 16

Simplifying the equation gives us:

7x + 21y - 2x + 7y = 33

Combining like terms, we get:

5x + 28y = 33

Now we have a new equation with only x and y terms. We can solve for one variable and substitute it back into either of the original equations to find the value of the other variable.
