Step-by-step explanation:
please give me brainlest and follow me
Set each factor EQUAL to zero to find the zeroes (since it is not actually equal to zero, you will use an open circle when graphing and an open bracket when writing in interval notation).
x = 0 x-1 = 0 x + 4 = 0
x = 1 x = -4
Next, choose a value to the far left, between each of the zeroes, and to the far right to evaluate if it makes a true statement when input into the given inequality.
far left (I choose -5): -5(-5 - 1)(-5 + 4) > 0 → (-)(-)(-) > 0 → negative > 0 FALSE
- 4 to 0 (I choose -2): -2(-2 - 1)(-2 + 4) > 0 → (-)(-)(+) > 0 → positive > 0 TRUE
0 to 1 (I choose 0.5): .5(.5 - 1)(.5 + 4) > 0 → (+)(-)(+) > 0 → negative > 0 FALSE
far right (I choose 2): 2(2 - 1)(2 + 4) > 0 → (+)(+)(+) > 0 → positive > 0 TRUE
Answer: (-4, 0) U (1, ∞)
Hi ty for the points, answer is the light blue one
The difference of two cubes is factored by
x^3-y^3=(x-y)(x^2+xy+y^2)
In this case it would be
C)
8 x 7 = 56
Just multiply the two, if the question was 7 + 8 x 7
then you'd multiply 8 by 7 and that would give you 56
then you'd add 7 for the final answer of 63 but you don't have to add 7 in this problem
