Answer:ITS 465
Step-by-step explanation:
4 + 6 + 5 = 15
AND THE DIFFERENCE IS 2 BETWEEN 6 AND 4
We will begin by working through Part (a): Simplify √18
To simplify a square root such as the one above, we must factor out perfect square numbers (this means we must find a number that multiplies to 18 and gives a whole number when we square root it). Using our knowledge that √9 is a perfect square, we should factor out a 9 from 18, as modeled below:
√18 = √(9*2)
We can separate this square root into two square roots multiplied together, as shown below:
√(9*2) = √9 * √2
Now, we should simplify √9, which equals 3, because 3 * 3 = 9.
√9 * √2 = 3 * √2 = 3√2
Therefore, √18 = 3√2.
Now, we can move on to the next problem: √6 * √15.
To begin this problem, we can multiply the square roots together, which means multiplying the numbers under the radical.
√6 * √15 = √(6*15) = √90
To simplify this, we use the same process as above:
√90 = √(10 * 9) = √9 * √10 = 3√10
Note: We know that this fully simplified because we cannot factor out another perfect square number from the number under the radical (10).
Therefore, your two answers are 3√2 and 3√10.
Hope this helps!
Answer:
amosc??????????????
Step-by-step explanation:
If you shift function f(x) a units right you'll get f(x-a) function.
So if you have f(x) = x², you'll get f(x-10) = (x-10)² - answer B
other formulas:
a units left: f(x+a)
a units up: f(x)+a
a units down: f(x)-a
