Use the Product Rule: x^ax^b = x^a + b
3x^-4 + 1 - 5 - 3(5x^-2x + 1)
Simplify -4 + 1 to -3
3x^-3 - 5 - 3(5x^-2x + 1)
Use the Product Rule: x^a x^b = x^a + b
3x^-3 - 5 - 3(5x^-2 + 1 + 1)
Simplify -2 + 1 to -1
<u>3x^-3 - 5 - 3(5x^-1 + 1)</u>
X=6 and CD Is 11 and AB is 9
The answer is -7
you have to do 42/x = -6 . when you cross multiply, you get:
-6x = 42
you solve for x by isolating it and diving -6 from both sides. that will get you the answer of -7
All you have to do is 5.99x4 which equals 23.96
A 1 = 13, d = 3;
S n = n/2 * ( a 1 + a n )
a 7 = a 1 + 6 d = 13 + 3 * 6 = 13 + 18 = 31
S 7 = 7/2 * ( 13 + 31 ) = 7/2 * 44 = 154
Answer:
D ) 154
