Answer:

50.05 cm^2

Step-by-step explanation:

Ok so first lets find the area of the rectangle before finding the attached triangle. You have to imagine a line separating this shape into a triangle and rectangle.

The rectangle's size is 6.5x5.5=35.75 cm^2

The rectangle's size is 11.7-6.5 to get the base length, which is 5.2

The height is 5.5

So it's 5.2*5.5/2=14.3 cm^2

14.3+35.75=50.05 cm^2

OLga [1]
The graph that best represents the function in this case, will be given by evaluating x in the function sometimes to build the number of points needed to describe the straight line. In this case, the graphic is shown in the attached file
 x= <span> 0 <span>1 2 3 4 5 6 7 8 9 <span> 10
</span></span></span><span><span> F(x)= 6 4 </span> 2 0 -2 -4 -6 -8 -10 -12 -14

What is the result of subtracting the secound equation from the first -4x-2y=-2 x-2y=9
crimeas [40]

Answer:

When we subtract the second equation  x-2y=9 from the first equation  4x-2y=-2, we get the value of x = 11/5.

Therefore, the required result is:

x = 11/5

Step-by-step explanation:

Given

The first equation

-4x-2y=-2

The second equation

x-2y=9

Let us subtract the second equation from the first equation

-4x-2y=-2

-

\:\underline{x-2y=9}

-4x - 2y - (x - 2y) = -2 - 9

-4x -2y -x + 2y = -2-9

-5x = -11

divide both sides by -5

\frac{-5x}{-5}=\frac{-11}{-5}

Simplify

x=\frac{11}{5}

Thus, when we subtract the second equation  x-2y=9 from the first equation  4x-2y=-2, we get the value of x = 11/5.

Therefore, the required result is:

x = 11/5
