Answer:
First you'd look at PEMDAS (parenthesis, exponent, multiplication, division, addition, and subtraction( you'd look at them in this order to solve the equation properly.))
So there is a parenthesis, that would be the 3(2^0). ignore the three, because you're focusing on the parenthesis. Any number other than zero with an exponent of zero will always be one. leaving you with 3(1).
So by now you should know (depending on your level of mathematics, That a number beside a single number in a parenthesis is multiplication. so 3 times 1.
Knowing that any number, other than zero, multiplied by 1 is the number itself, The answer is 3
In short, 3(2^0) = 3
Answer:
20
Step-by-step explanation:
the two closest are 20 and 30
21 is the next digit after 20 and the closest to it.
21 is 9 away from 30 and is farther.
Answer:
Step-by-step explanation:
Multiply both denominators till they are the same than Multiply numerators by the number you multiplied by
Answer:
Step-by-step explanation:
You can use these Cramer's formulas to solve for x and y:
where
So,
( 2x − 27 ) ( −x + 15 )
= ( 2x + −27 ) ( −x + 15 )
= ( 2x ) ( −x ) + ( 2x ) ( 15 ) + ( −27 ) ( −x ) + ( −27 ) ( 15 )
= −2x^2 + 30x + 27x − 405
= −2x^2 + 57x − 405
