Answer:
Step-by-step explanation:
Use the formula for the area of a triangle,
Area of a triangle = 
7). Area of the triangle = 
= 74 km²
8). Area of the triangle = 
= 30.8 cm²
9). Area of the triangle = 
= 56 m²
10). Area of the triangle = 
= 42.35 km²
Answer: b would actually be the closest but the exact answer is 145.2
x+y=23 and 10x+24y=426 can be used to determine the number of small and large boxes shipped where x represents the number of small boxes and y represent the number of large boxes.
Step-by-step explanation:
Given,
Volume of small box = 10 cubic feet
Volume of large box = 24 cubic feet
Total boxes shipped = 23
Combined volume = 426 cubic feet
Let,
x represent the number of small boxes.
y represent the number of large boxes.
x+y=23
10x+24y=426
x+y=23 and 10x+24y=426 can be used to determine the number of small and large boxes shipped where x represents the number of small boxes and y represent the number of large boxes.

Answer:
B. 128 square centimeters
Step-by-step explanation:
So first make the top triangle part its own figure. By using information provided you can figure out the height of the triangle would be 3 by subtracting 11 from 14. Take 3 multiply it by the base and then 1/2 to get 18. Then find the area of the rectangle which would be 10 times 11 which is 110. Add the areas of the two parts, 110 and 18 to get 128.
