to answer this you need to do -5+14.3 to get you answer which would be
-5+14.3
9.3
so n=9.3
hope this helps
Answer:
x=9
Step-by-step explanation:
All measurements of the interior angles equals up to 180 degrees when added together, therefore add them all together and set it equal to 180.
7x+2+4x+7+8x=180
-Combine like terms
19x+9=180
-Subtract 9 on both sides
19x=171
-Divide by 19
x=9
Answer:
Area: 57cm
Perimeter: 29cm
Step-by-step explanation:
Area: Length x Width
9.5cmx6cm
Perimeter: You add up all the lengths (sides) of the shape.
Perimiter is where you add all the sides and a rectangle has four sides.
28/4=7
But the length is 4m longer then the width so, 7+4=11 but if we do 11+11+7+7= 36. But that is not the perimeter so 7-4=3
And if we do 11+11+3+3=28!
Therefore the length of the rectangle is 11m and the width is 3m
To find the area we just do 11•3=33
The only reason this is long is because i explained and put it into detail but its pretty simple and short once you get the hang of it :)
