Answer:
-273
Step-by-step explanation:
find the common difference:
d = 7 - 11 = - 4
a_1 = 11
a_72 = (72 - 1)* (-4) + a_1
a_72 = (71)* (-4) + 11
a_72 = -273

-2x^3 - 4x^2 + 4x
-2x^3 = -2x(x^2)
-4x^2 = -2x(2x)
4x = -2x(-2)
so GCF= -2x
-2x3 - 4x2 + 4x = -2x(x^2 + 2x - 2)
answer is B. -2x(x^2 + 2x - 2)
Answer:
- 40
Step-by-step explanation:
When a = 4, and x = -4:
Evaluating algebraic expressions simply involve substituting the given values for <em>a</em> and<em> x</em> into the expression, -9a + x.
Hence, -9a + x = -9(4) + (-4) = -36 - 4 = -40
Therefore, the correct answer is -40.
