for x=-2
x^4+3x^3+3x2-3x-4
(-2) ^4+3(-2) ^3+3(-2) ^2-4=16+(-24)+12-4=0 ok
For x=0.811
(0.811) ^4+3(0.811) ^3+3(0.811) ^2-4=0.4326+(1.6002)+1.9731-4=0 ok
Answer:
4 and 8
Step-by-step explanation:
brainliest please?
If you multiply the number of students times 8 you get 96, but if you multiply the students by 8 you need to multiply the adults by 8 as well. Which leaves you with 16 adults. Is there more to this equation? I feel like this is only part of it.
Given:
Cost of one pound of apples = $1.98
To find:
The cost of 0.75 pound of apples.
Solution:
We have,
Cost of one pound = $1.98
So, cost of 0.75 pound of apples = 0.75 × cost of one pound of apples
Therefore, the cost of 0.75 pound of apples is $1.485.
To convert a fraction to percent, divide the numerator (which also means top number) by the denominator (which also means bottom number). Example: To convert the fraction 3/4 to percent, divide 3 (top number) by 4 (bottom number) and the answer is.75.
