Answer:
(t^2 -4) (t^2 +4)
(t-2)(t+2)(t^2+4)
Step-by-step explanation:
t^4 - 16
We can write this as the difference of squares
We know the dfference of squares is
(a^2 - b^2) = (a-b) (a+b)
( t^2 ^2 - 4^2) = (t^2 -4) (t^2 +4)
We can write t^2 -4 as the difference of squares
t^2 -4 = t^2 -2^2 = (t-2)(t+2)
Replacing this in
( t^2 ^2 - 4^2) = (t^2 -4) (t^2 +4) = (t-2)(t+2)(t^2+4)
x=7
Step-by-step explanation:
median is the middle no.=6 and x
it will be 6+x=13
take 6 to the other side=7, hence x=7
Answer:
2/1
Step-by-step explanation:
x1=1 ,y1=3
x2=2 , y2=5
then
m= 5-3/2-1= 2/1
Well for this you have to do 4 1/8 - 2 3/8. You cannot subtract 1 - 3, so you have to take away 1 from three and add 8 to 1 so now the equation is 3 9/8 - 2 3/8. This is equal to 1 6/8 or 1 3/4, so no, she did not use 2 2/8 yards of fabric.
Answer:
1) The correct answer is option D.
2)The correct answer is option A.
3)The correct answer is option A.
4)The correct answer is option B.
Step-by-step explanation:
1) Scientific notation is defined mathematical representation used to to represent the a decimal number which present between 1 to 10 multiplied by 10 raised to power equal ti some integer. For example:

Hence, the correct option is D.
2) The scientific notation of number 0.0000000708.
0.0000000708 = 
Hence,the correct answer is option A.
3)When the power of the number ten is in negative.
- if the power is more negative number will be smaller.
- If the power is less negative the number will greater.
Greatest number from the given option is 

4) 

Hence, the correct answer is option B.
