It’s 21 because 252 divided by 12 equals 21
Answer:
Step-by-step explanation:
Area can be calculated if the length of the base and height given.
<u>According to measurements:</u>
- A . Impossible, as the length of base is not given
- B. Possible. A = 4*2 = 8 cm²
- C. Impossible, the the length of height is not given
- D. Possible. A = 4*3 = 12 cm²
- E. Possible. A = 5*2 = 10 cm²
- F. Impossible, the the length of height is not given
I'll only answer the first question, 'The data representation is useful because it tell and shows you what industry, what is the yearly cost and the highest qualifications.'
For the first box on the left hand side, the answer is m < 1 + m < 2 = 180 as they are a linear pair
The first box in the right-hand column is "linear pair postulate" as its very similar to the previous line
The second box on the left-hand side is m < 1 + m < 2 = m < 2 + m < 3. Essentially we're doing replacements. Similar to how x+3 = 10 turns into 7+3 = 10 when we plug in x = 7
The second box on the right-hand side is "subtraction property of equality". We subtract "m < 2" from both sides to end up with m < 1 = m < 3
This equation in word form would be 7x -6 = -20, and the solution to that equation is x = -2
