Answer:

Step-by-step explanation:
In division of powers with the same base, we must subtract the exponent of the denominator from the exponent of the numerator:

Then applying this to the problem:

Eliminating the parentheses:

The answer is C. First, the area of the plot should be the multiplication of the two side lengths, so 11.7 * 15.4=180.18. However, we have to look at the significant digits to decide to what digit should we round the answer to. Since both 11.7 and 15.4 are accurate to the tenths digit, 180.18 should also be so, so we should round it to 180.2.
So, if you're trying to ask what 12 divided by 3 is, then the answer is four. (Using inverse operation), because 4x3=12. But, make sure you put the label! The answer is $4.
Answer:
The 3 angles are 62 2/3, 44 2/.3 and 72 2/3 degrees.
Step-by-step explanation:
let x be the first angle then the the second angle is x - 18 and the third angle = x + 10
The 3 angles add up to 180 so:
x + x - 18 + x + 10 = 180
3x = 180 + 18 - 10 = 188
x = 188/3 = 62 2/3 degrees.
x - 18 = 44 2/3
x + 10 = 72 2/3.
