Answer:
If the numbers next to the "x" are "carroted" ( ^ ) then the answer is
-3x^4 + 9x^3 -8x^2 -2x +12
Step-by-step explanation:
Basically, you just add the like terms together.
Answer:
Step-by-step explanation:
Question 1:
First, write the equation out:
4(x+3)=7x-3
solve for x:
4x+12=7x-3
15=3x
x=5
Question 2:
Do the same on the second question:
30-x=3x-6
36=4x
x=9
Answer:
A) Values in the solution set satisfy both inequalities.
B) It is the intersection of two solution sets.
Step-by-step explanation:
We denote intersection as AND.
Take those sets. The intersection is what A and B share.
Find area of circle
A=pir^2
A=pi5^2
A=25pi
then find how much the central angle is
whole circle is 2pi radians
(3pi/2)/2pi=3pi/4pi=3/4
it is 3/4 of whole area
area=25pi units^2
3/4 times 25pi=75/4pi units^2=
18 and 3/4 pi square units=
18.75ip square units
