The square root of 2 is an irrational number (1.4)
Answer:
Side lengths of 12,8,8
Step-by-step explanation:
In an isosceles triangle the base is different from the other 2 sides which are the same so
28=12+2x (x being the side of the repeat sides)
14=6+x (divide both sides by 2)
8=x (subtract 6 from both sides) so
Side lengths of 12,8,8
Answer: a1=6
An = An-1 - 4
Step-by-step explanation:
N represent what number in the sequence you choose. So in the equation n-1 would be the umber in the equation subtracting 1 then subtracting the difference. The factor you are multiplying by in this sequence is -4. You find the difference by taking any number in the sequence and dividing it by the previous number in the sequence.
Answer:
s=√7-1
s=-(√7+1)
Step-by-step explanation:
s^2+2s-6=0
or,s^2+2.s.1+1^2=6+1^2
or,(s+1)^2=6+1
or,(s+1)^2=7
or,(s+1)^2=(±√7)^2
or,s+1=±√7
either,
s=√7-1
or,
s=-(√7+1)
Answer: 
Step-by-step explanation:
Let's look at the numbers that we count.
The question says not multiple of 2, so we have to count to following numbers:
1 , 3 , 5
And in total there are 6 numbers, so our probability is
=
