Answer:
Area of equilateral triangle:36cm
Square area:12cm
Step-by-step explanation:
We need to find the corresponding relationship, it is not difficult to find that this is a simple quadratic function problem.
I used pictures to express the process. You can click to view. I'm not English either. I'm Chinese, but I believe that academics know no boundaries.
Answer:

Step-by-step explanation:
-15 both sides and then it’s will be
5x = 13 then u divide both sides over 5 and the answer will be ( X=2.6 )
Answer:
a ≠ 2
Step-by-step explanation:
Given

The denominator of the rational function cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the value that a cannot be, that is
- 3a + 6 = 0 ( subtract 6 from both sides )
- 3a = - 6 ( divide both sides by - 3 )
a = 2 ← excluded value
Answer:
P = 14
Step-by-step explanation:
First of all we know that P - 12 = 2
So, basically all we have to do is add 12 plus 2.
12 + 2 = P
P = 14
So, P should equal 14.
