PLEASE HELP WITH GEOMETRY!! WILL GIVE BRAIN!!!

xenn [34]

Answer:

1,726 cm

Step-by-step explanation:

it boils down to this equation:

2(19×29)+2(19×6.4)+2(29×6.5)

bc if you look closely, it's just each side twice (hope that makes sense)

then you work down from there

2(551)+2(123.5)+2(188.5)

1,102+259+337

Follow the directions to solve the system of equations by elimination. 8x + 7y=39 4x – 14y = -68

harina [27]

Step-by-step explanation:

Hey there!

Here;

The equations are;

$8x + 7y = 39.......(i)$

$4x - 14y = - 68..........(ii)$

Multiplying equation (i) by 2.

16x + 14y = 78

4x - 14y = -68

20x = 10

$x = \frac{10}{20}$

x = 1/2.

Putting value of 'x' in equation (i).

$8 \times \frac{1}{2} + 7y = 39$

$4 + 7y = 39$

$7y = 3 9 - 4$

$y = \frac{35}{7}$

Therefore the value of y is 5.

Check:

Put value of x and y in equation (i).

8x + 7y = 39

$8 \times \frac{1}{2} + 7 \times 5 = 39$

$4 + 35 = 39$

$39 = 39$

(True).

Therefore, the solution is ; (1/2,5).

Hope it helps...
