Answer:
x=8
Step-by-step explanation:
You would set them equal to each other to get 9x-13=6x+11.
You would them move 6x over so -6x on both sides. This would then get you 3x-13=11.
Then move the -13 over so add 13 to both sides to get 3x=24
Then get x by itself so divide by 3 to get x=24/3.
Then that simplified is 8
Because even though 'a' and 'b' are rational, and their squares are
also rational, that doesn't guarantee that the sum of their squares
has a rational square root.
Examples:
1 and 2
Sum of squares = 5
√5 is irrational
2 and 3
Sum of squares = 13
√13 is irrational
4 and 5
Sum of squares is 41
√41 is irrational
'c' is rational only when 'a', 'b', and 'c' form a . . . . . wait for it . . . . .
a 'Pythagorean triple'.
Examples:
3 and 4
Sum of squares is 25
√25 = 5 is rational yay
5 and 12
Sum of squares is 169
√169 = 13 is rational yay
Answer:
Step 2
Step-by-step explanation:
Because when you see number (70)
it's a pos+ so take it to another side to be neg- .
Then : 40-70=-30
NOT 110!!
Answer:
The correct answer is A) x^6y^8
Step-by-step explanation:
The easiest way to find this is to first square the second term.
(-x^2y^3)^2 = (x^4y^6)
Now we multiply that by the first parenthesis.
(x^2y^2)(x^4y^6) = x^6y^8
