She totally missed seeing the number 30, as 15 x 2 is 30 and 6 x 5 is 30. 30 is her LCM
Answer: The sum of two Irrational numbers will be irrational
Step-by-step explanation: Because they are irrational so its result will also be irrational
Answer:
B. 3
Step-by-step explanation:
First of all we will define rotational symmetry.
Rotational symmetry is when a shape looks the same after some rotation or less than one rotation.
The order of rotational symmetry is how many times it matches the original shape during the rotation.
So, for the given shape the rotated shape will match the original shape three times so the order for symmetry for the given shape is 3.
Hence,
the correct answer is B. 3 ..
We have been given a system of nonlinear equations.

In order to solve this system we can first equate the two equations in order to get a quadratic in x.

Our next step is to bring all the terms on one side.

Now we have to solve this equation. We can solve it by factoring using the splitting middle term method.



Upon setting each of these factors equal to zero using zero product property we get

Upon solving both these equations we get

Now we can substitute these values of x in the equation

We get


Therefore, our final set of solutions are

Well to find the volume of a pyramid, you take the base (12mm) times the height (15mm) times 1/3 to get an answer of 60mm squared.
Hope this helped.
