Answer:
there should be multiplication sign...so value will be (-351)
Area of the pentagon: 342 cm2
Step-by-step explanation:
The figure of the pentagon is missing: find it in attachment.
The area of the pentagon can be seen as the area of 5 equal triangles, each of them having a base equal to the length of the side of the pentagon,
L = 14.1 cm
and the height of each triangle can be found by using Pythagorean's theorem:

The area of each of the 5 triangles is

Therefore, the area of the pentagon is 5 times this area:

Answer:
identity
Step-by-step explanation:
Answer:
Slope intercept form: y=mx+b; where m is the slope and B is the y intercept
For 2 lines to be parallel they must have the same slope. Thus, the slope of the new line is going to be 1.
To find the y intercept plug in the slope and the x, y into the equation y=mx+b:
y=mx+b
y=1x+b
2=1(2)+b
2=2+b
0=b
b=0
Now that we have your slope and y intercept we can make the equation:
y=1x+0
y=x
