8000=2 oumces
????=16 oumces
8000 x 16 divided by 2
answer=64,000 crocus
3^3 = 27
5^2 = 25
27 - 25 = 2
integral of 2 = 2x
(2x) evaluated from -2 to 0
= (0) - (2(-2)) = -(-4) = 4
If you did not make any mistakes in typing your question
the answer would be 4

Answer:
Step-by-step explanation:
If you call "5x-2x^2+1" an "equation," then you must equate 5x-2x^2+1 to 0:
5x-2x^2+1 = 0
This is a quadratic equation. Rearranging the terms in descending order by powers of x, we get:
-2x^2 + 5x + 1 = 0. Here the coefficients are a = -2, b = 5 and c = 1.
Use the quadratic formula to solve for x:
First find the discriminant, b^2 - 4ac: 25 - 4(-2)(1) = 25 + 8 = 33
Because the discriminant is positive, the roots of this quadratic are real and unequal.
-b ± √(discriminant)
Applying the quadratic formula x = --------------------------------
2a
we get:
-5 ± √33 -5 + √33
x = ----------------- = --------------------- and
2(-2) -4
-5 - √33
---------------
-4
