Answer:
The base is 4cm and the height is 5cm.
Step-by-step explanation:
This is a solve the system question. Call H the height of the triangle and B the base. The question tells us:
and
Sub the first equation into the second (as H is already isolated). You will end up with a quadratic equation - solve that any way you wish (e.g. quadratic formula). I've provided the factored form below which shows you the roots:
In this question, we take B=4. You can't have a negative side length so the other answer is eliminated. Now sub the value for B into either of the original equations. I'll use the first, again because H is already isolated:
1) Solving 
we get 
2) Solving 
we get 
3) Solving 
we get 
Step-by-step explanation:
We need to solve the following expressions:
1)
We will solve this expression by factoring common terms:
Factoring 4 from 4a+4b and -c from -ac-bc
Taking common term
2)
We will solve this expression by factoring common terms:
Taking 8 as common term:
3)
We can solve the expression by breaking the middle term into 2

Answer:
Yes, Fiona is correct
Step-by-step explanation:
WHen the pythagorean theorem is applied to the side lengths (2^2 + 4^2 = c^2), the result for c^2 is 20. The correct answer would be sqrt.20. But Fiona is also correct becuase sqrt of 20 can be simplified to sqrt.4 * sqrt.5; which equals 2*sqrt.5
Step-by-step explanation:
First, find 12 percent of 1,150,
12 percent of 1,150 = 138.
Now, add 1,150 + 138,
1,150 + 138 = 1,288
Hope I helped, if not, at least I tried.
