If w represents the width of a rectangle with a length of 12 centimeters and an area of 590 square centimeters, what is the best

Y_Kistochka [10]

The formula for the area of a rectangle is...

Area = length x width

A = L x W

What we know so far...

Area is 590 cm^2

length is 12 cm

width is unknown

Plug all of these into the equation for area of a rectangle:

590 = 12 * w

or

590 = 12w

Letter A is the correct answer

Hope this helped!

Item 9 Write an equation that you can use to find the value of x. Perimeter of triangle: 16 in.

Tanya [424]

Answer:

16 = 3x

Step-by-step explanation

Find the diagram attached.

Perimeter = sum of all its sides

Sum of all its sides= x+x+x

Sum of all its sides = 3x

Given perimeter = 16in

Equating both;

3x = 16

x = 16/3

x = 5.33in

Hence the value of x is 5.33 and the required equation is 16 =3x

How can I solve this:

Fynjy0 [20]

Hey !

The Sum of Roots is -6

Manipulate the Equation to Get :

$(3a + 6) {x}^{2} + (2a - 4)x + (a + 4) = 0$

Now, by Viete,

$- 6 = \frac{(4 - 2a)}{(3a + 6)}$

$18a + 36 = 2a - 4$

$16a = - 40$

$= > a = \frac{ - 5}{2} = - 2.5$
