Answer:
Step-by-step explanation:
The area of a rectangle is length times width.
We divide the polygon into 4 rectangles:
The area of the first rectangle is :
The area of the second rectangle is
The area of the 3rd rectangle is
The area of the fourth rectangle is
Putting all together, the area of the polygon is;
0.16+1.44+1.6+0.4=3.6m²

Step-by-step explanation:
<h3>Part A</h3>
Gas in liquid state at
- 40° F < t < 140° F
<h3>Part B</h3>
The graph is the line segment from the point -40 to 140 on the number line, with both points open circles and shaded in between those 2 points
Solution set is all numbers greater that -40 and smaller than 140.
<h3>Part C</h3>
-49° F is smaller than -40° F, so the gas would freeze
Answer:$104.5
Step-by-step explanation:
cats=c
Dogs=d
2c+3d=455
d=82
Substitute d=82 in 2c+3d=455
2c+3(82)=455
2c+246=455
Collect like terms
2c=455-246
2c=209
Divide both sides by 2
2c/2=209/2
c=104.5
1 cat cost $104.5
The answer is 9. because... (8+9) + 32= 49
