By simplifying given phrase "twice the sum of a number cubed and nine" and evaluating it for r = 3 we got that Jessica done it correctly
<h3>What is cube of any number ?</h3>
Cube of any number means multiplying that number with itself 3 times.
For example
Here given phrase is
twice the sum of a number cubed and nine
let number be r
We can write it as
Now evaluating it for r=3
Now we can simplify it as

When you multiply a decimal with a decimal, you just multiply like you would with whole numbers. Then, you count the numbers to the right of the decimal for both multiplicand an multiplier. If the equation was 8.374 x 1.234, then you would put the decimal 6 spots to the left of the product. For the first step of solving this is just multiply like and decimal is not there. The answer would be 10333516. Then you count the number right of the multiplicand and the multiplier. In total there is 6 numbers, so you put the decimal 6 spots to the right. The end result would be 10.333516. Hope this helped!

Step-by-step explanation:
Square root is this 4 and -4 are square roots to 16 because 4^2= 16
Let's check if (3 , 6) is the point of intersection of the given lines ~
and
If the point is the point of intersection of these two lines, then it should satisfy both the equations ~
let's try each of them, using x coordinate of point.
So, the point didn't actually satisfy one of the equation. hence we can infer that the given statement is wrong.
