Answer:
The answer to this would be C. 1 / fg.
We know that
<span> the highest that this mountain can be is 27849 feet
because this number (27849 feet) rounded </span>to the nearest hundred is 27800 feet, however if the number were 27850 the number rounded to the nearest hundred would be 27900
hence
the answer is
27849 feet
We need to factor by grouping. Group xy with -4x and 2y with -8 and factor each group.
(xy-4x)+(2y-8)
x(y-4)+2(y-4)
b. (x+2)(y-4)
Hope that helps.
<h3><u>Given</u> :</h3>
- 2x²y - 4xy², x = - 1 & y = 1
<h3><u>To Find</u><u> </u> :</h3>
<h3><u>Solution</u> :</h3>
2x²y - 4xy²
<u>Substituting the value of x & y</u>,
= 2(- 1)² × 1 - 4(- 1) × 1²
= 2 × 1 × 1 + 4 × 1
= 2 + 4
= 6
<u>Hence, The value of the expression is 6</u>.
5 + (n - 1)²
5 + (n - 1)(n - 1)
5 + (n² - n - n + 1)
5 + (n² - 2n + 1)
n² - 2n + 1 + 5
n² - 2n + 6 = 0
n = <u>-(-2) +/- √((-2)² - 4(1)(6))</u>
2(1)
n = <u>2 +/- √(4 - 24)</u>
2
n = <u>2 +/- √(-20)
</u> 2
n = <u>2 +/- 2i√(5)</u>
2
n = 1 <u>+</u> i√(5)
n = 1 + i√(5) n = 1 - i√(5)
The answer is equal to B.
