Start with the given equation:
Substitute known values:
Evaluate:
Similarly:
You posted the question twice ... I have repeated the answer here .. .
Find the area of all the sides:
10 x 9 = 90
9 x 8 = 72
1/2 x 6 x 8 = 24
1/2 x 6 x 8 = 24
6 x 9 = 54
Add them up:
90 + 72 + 24 + 24 + 54 = 264 square metres
Answer:
12
Step-by-step explanation:
21=31
31=7+2-3+0=12
This is correct because linear equations mean add subtract divide and multiply instead of finding roots and squares
