Answer:
5x^2-12x-2
Step-by-step explanation:
Use distributive property, then add like terms. See file below for steps.
The answer to that question is 250.
1/3 x 9a then 1/3 x n plus -1/2 x 4a the -1/2 x 2b the add the two b's together then add the two a'S together the write _a + _b
Answer: See below
Explanation:
Write an equation for nth term:
a + d(n - 1)
a = 8 (first term)
d = -6 (common difference)
8 - 6(n - 1)
= 8 - 6n + 6
= -6n + 14
Find a 50:
-6(50) + 14
= -300 + 14
= -286
If the problem is 6r•s•4rt•10rst, then the answer is 240•r^3•s^2•t^2.
