Answer: b and c cuz an equation always has an equal sign
Step-by-step explanation:
Answer:
40 years old
Step-by-step explanation:
Let's imagine a+b=63
63-12=51 (since they were both 6 years younger)
A is double B
34+17=51
34/2=17
You need to add the 6 years back onto the mothers age - 34+6=40
40 years old
For any value, e.g. a, to the nearest x units, the upper and lower bounds are:
(a + x/2) and (a - x/2)
For your question, there are three dimensions so:
Dealing with the first one, we have 24 cm to the nearest 2 cm so the boundaries are:
Upper boundary: 24 + 2/2 = 25
Lower boundary: 24 - 2/2 = 23
The second dimension is the same as the first in value and is also given to the nearest 2 cm so the boundaries are the same as for the first.
The third dimension is 20 cm to the nearest 2 cm so the boundaries are:
Upper boundary: 20 + 2/2 = 21
Lower boundary: 20 - 2/2 = 19
To get the largest possible area, we take the upper bounds of all the dimensions and multiply them so:
25 * 25 * 21 = 13125 cm³
I think its A 93 cm because when i work out the problem i get 93
