We know that the formula for the Area, A of a triangle is given as:
.....(Equation 1)
In our question we already know that
and

Substituting these values in (Equation 1) we will get:

Multiplying both sides by 2 we will get:

In-order to find base we will isolate it by dividing both sides by 15. Thus, we get:

Thus, the answer is, base=27 mm.
Answer:
r = q -6
Step-by-step explanation:
q= 
You do kcf (keep it, change it, flip it)

I am assuming you mean Ratio into Fraction.
It is really simple, actually. Just put one number on top of another (divide would be a better word).
I have a ratio A:B, which is 1:2.
I can put 1 on top of 2 to create the fraction <u>1/2</u> to say that A is <u>1/2</u> of B.
A=1/2B
I can also put 2 on top of 1 to create the fraction <u>2/1</u> to say that B is <u>2/1</u> of A, or 2 times of A.
B=2A

Answer: Average rate of change = 4</h3>
==========================================================
Explanation:
When we have an interval [a,b], the average rate of change over this interval is given by the formula

You probably can notice that we have something that looks eerily similar to the slope formula. That's because average rates of change are basically the same as the slope of the straight line through the endpoints of the interval. The f(b)-f(a) is the change in y of f(x) outputs. The b-a down below is the change of x values when going from x = a to x = b.
-------------------
Let's evaluate the function at x = 1
f(x) = x^2+1
f(1) = 1^2+1
f(1) = 2
Repeat for x = 3
f(x) = x^2+1
f(3) = 3^2+1
f(3) = 10
--------------------
We have enough info to evaluate the original formula I mentioned earlier

The average rate of change on this interval is 4
This is the same as saying the slope of the line through (1,2) and (3,10) is m = 4
See the graph below.
