Answer:
you put it in the toilet into your pop
To simplify the square roots, we apply the square root to the number first, followed by the variable. So for 9x^2, we take the square root of 9 (which is 3), then the square root of x^2 (which is x).
The square root of (9x^2) is 3x. The square root of (18y^2) is (3sqrt2)y. Dividing the first term by the second term gives:x / y(sqrt2).If the final answer must be rationalized, it should be x(sqrt2) / 2y.
- - Solve:
Start of by simplifying both sides of your problem.
3*2x+3*-7=32
6w+-21=3
6w-21=3
- - Now you need to add 21 to both sides to be able to finish solving.
6w-21+21=3+21
6w=34
- - Final step:
Answer: w=4
Answer:
52.16
Step-by-step explanation:
So, Lets find out the discount first. Since the shoes are 30% off, that means the shoes are 70% of their original price, so lets multiply the original price of 69 by .7. 69*.7=48.3
Now to find the sales tax we need to multiply the price we got finding the sale by 1.08 since the sales tax is added on not removed from the price. 48.3*1.08=52.16
The prices after the sale and including tax is 52.16
Answer:
Step-by-step explanation:
First method: for (x+3)^2 if you multiply (x+3)(x+3) you get x^2+6x+9 which doesn't equal x^2+9
Second way: plug in a variable for example (2+3)^2= 25 and 2^2+9=13 so 13 doesn't equal 25
