Is the surface a rectangle?? If so, then the surface area would be 35
The answer would be a^9 (a to the ninth power) because you would add the exponents.
Standard Form looks like this:

Also, A cannot be negative and there are no fractions in Standard Form.
Now that we know the rules of Standard Form, let's get x and y on one side.
-2/3y = 2 + 8/15x
Subtract 8/15x from both sides.
-8/15x - 2/3y = 2
Multiply 2/3 by 5/5 to get a common denominator.
-8/15x - 10/15y = 2
Multiply everything by 15 to rid of the fractions.
-8x - 10y = 30
Multiply everything by -1 to make A positive.
8x + 10y = -30
8x + 10y = -30
Answer:
12.6
Step-by-step explanation:
The question requires you to estimate the product of 0.12 * 105
12/100 * 105 ----multiply 12 and 105
12 * 105 = 1260
Divide the answer by 100
1260/100 = 12.6
