720 starting off from the Main Street being 40 percent leading the child to explode into 720 pieces
Answer:
95>=X <=100. More or equal to 95 or equal or less than 100.
Step-by-step explanation:
The Total of the first score is needed first
81+87+ 94+93=355
The total of this score
Let X be the 5TH score we are looking for
(355+ X)/5= 90
355+X= 450
X= 450-355
X= 95 the person needs to sore between 95 and 100 ( which is the highest possible score).
9514 1404 393
Explanation:
The correct order of the steps is ...
- (Given)
- (Definition of supplementary)
- (Substitution)
- (Subtraction ...)
- (Definition of congruent angles)
A proof always starts with "given". It always ends with a statement of what you have proved.
To fill in the sequence between these, it helps to think about what the relationships are and why you can conclude that the theorem is correct.
Answer:
x=√2, x=-√2, x= 3 and x=-3
Step-by-step explanation:
We need to solve the equation x^4 - 11x^2+18=0
We can replace x^4 = u^2 and x^2 = u
So, the equation will become
u^2 -11u+18 = 0
Factorizing the above equation:
u^2 -9u-2u+18 =0
u(u-9)-2(u-9)=0
(u-2)(u-9)=0
u=2, u=9
As, u = x^2, Putting back the value:
x^2 =2 , x^2 =9
taking square roots:
√x^2 =√2 ,√x^2=√9
x=±√2 , x = ±3
so, x=√2, x=-√2, x= 3 and x=-3
Answer:
4t
Step-by-step explanation:
All we are doing is combining like terms and since all of then have a "t" in it we would just add the 4 "t's" together like normal addition.
