For what values of a does the equation a+x= 1+xa^2 have no solution?

Answers

Answer 1

Answer:

Answer:

We have the equation

$a+x= 1+xa^2$

we leave the terms with x on the left side of the equation and the independent terms on the right side.

$x-xa^2=1-a\n(1-a^2)x=1-a\n$

resolving for x we have that

$x=(1-a)/(1-a^2)$

Since we need that the equation doesn't have solution, then it is necessary that the denominator of x be 0 and this occur when $1-a^2=0\n1=a^2\na=\pm1$

Then, for $a=\pm1$ the equation hasn't solution

i only know the answer for the second question.
the answer is20
11-3=8
8*5=40
40-30=10
10*2=20
the first one is 48
1+2=3
3*4=12
12+3=15
15+1=16
16*3=48

The answer of question #1 is 48.
To solve this, first you have to solve the (2+1) and that equals 3, now you solve 4(2+1), and that equals 12. Next, you solve the [4(2+1)+3] and that equals 15. Then, you solve {1+[4(2+1)+3} and that equals 16. Lastly, 3{1+[4(2+1)+3} equals 3 times 16=48.

3{1+[4(2+1)+3}=3[1+(4x3+3)]
=3(1+12+3)=3x16=48

Is 100 feet greater or less than 3 yard

Answers

$1yard=3feet$

So for it to be even, you need 33.33 yards

But there is only 3 yards so that means 100 feet is greater

Even if you did a mistypo and meant 10 feet, it would still be greater than 3 yards

100 feet is fairly way bigger than 3 yards
