What is the combined perimeter of these two rectangles 4x+5 and 2x+7 and 3x+14 and 3x

Marysya12 [62]

Answer:

The combined perimeter is 24x + 52 units

Explanation:

1- Let's get the perimeter of the first rectangle:

The dimensions of the first rectangle are 4x+5 and 2x+7 units

Perimeter of rectangle = 2(length + width)

Perimeter of first rectangle = 2 (4x+5+2x+7)

Perimeter of first rectangle = 2 (6x + 12)

Perimeter of first rectangle = 12x + 24 units

2- Let's get the perimeter of the second rectangle:

The dimensions of the second rectangle are 3x+14 and 3x units

Perimeter of rectangle = 2(length + width)

Perimeter of second rectangle = 2 (3x+14+3x)

Perimeter of second rectangle = 2 (6x + 14)

Perimeter of second rectangle = 12x + 28 units

3- Finally, let's get the combined perimeter:

Combined perimeter will be the summation of the two perimeters

Combined perimeter = 12x + 24 + 12x + 28

Combined perimeter = 24x + 52 units

Hope this helps :)

2y/5y cube + 4y square + 6y

timama [110]

Answer:

here down is the answer

(2y/5y)^3+4y^2+6y

8y^3/125y^3 +16y^2+6y

8/125+16y^2+6y

8/125+16y^2+6y=0

16y^2+6y+8/125=0

it is in the form of quadratic equation

formula :

x=(-b+-square root of b^2-4ac) /2a

here a=16,b=6&c=8/125

x=(-b+-square root of b^2-4ac)/2a

x=(-6+-square root of 36-4.09)/2a here 4.09 came by calculation

x=(-6+-31.91)/2

x=(-6+31.91)/2 first (+);

x=25.91/2

x=12.955;

x=(-6-31.91)/2 then(-);

x=-37.91/2

x=-18.955 ;

ans is = 12.955&-18.955;
