Answer: 
Step-by-step explanation:
Given
The parabolas are
and 
Find the point of intersection of two parabolas

Obtain y using x

Area enclosed between the two is

Thus, the area bounded by the two parabolas is
sq. units.
4 -3 5 6
-6 -24 162 -1002
-----------------------------------
4 -27 167 -996
4x^2 - 27x + 167 remainder - 996
Answer:
-4 square inches
Step-by-step explanation:
its because the 5 pictures together make 21
Answer:

Step-by-step explanation:
In order to solve this you just have to remember the formula for the sides and hypotenuse of the triangle rectangle:

Since A and B are equal we will use X to represent them both:

ANd by solving the equation we get that the length of the legs of the triangle rectangle with a hypotenuse of 4cm is 
Answer:

Step-by-step explanation:
Since we see that 3/7 is multiplied by itself three times, we can use exponents as a shorter way to write this. The expontent tells us how many times the base number, 3/7, is multiplied by itself.
= 
We then multiply by -1 to (3/7)^3 to get the exact answer.
