Answer:
x=9
Step-by-step explanation:
The expression is for the interior angle of the hexagon; one interior angle is equal to .
Since an interior angle of a hexagon measures 120°, we have the equality
.
Now it is just a matter of solving for
11x=120-21
11x=99
x=99/11
x=9
Step-by-step explanation:
log(7·x + 7) = 1
7·x + 7 = 10^1
7·x = 10 - 7
x = 3/7 = 0.4285714285
Base 10:
97.536 = 9 x 10 + 7 x 1 + 5 x 0.1 + 3 x 0.01 + 6 x 0.01
Number Names:
97.536 = Ninety-Seven and Five Hundred Thirty-Six Thousandths
Expanded Form:
97.536 = 90 + 7 + 0.5 + 0.03 + 0.006
Answer:
2(9w - 3)
Step-by-step explanation:
6w + 3(4w - 2) = ? ( ? - 3)
6w + 12w - 6
18w - 6
2(9w - 3)
6w + 3(4w - 2) = 2(9w - 3) <===
That is a quadratic equation. To find its square, think of two numbers that when multiplied, the answer would be the last term, constant 9 and if those two numbers are added, the answer would be the middle term, the constant 10 with variable x. These are positive integers 9 and 1, respectively.
(x² + 10 x + 9) = 0
= (x + 9 ) (x + 1)
Using the FOIL method to check, the square is equal to the quadratic equation.
