Answer:
Step-by-step explanation:
Rewrite this quadratic equation in standard form: 2n^2 + 3n + 54 = 0. Identify the coefficients of the n terms: they are 2, 3, 54.
Find the discriminant b^2 - 4ac: It is 3^2 - 4(2)(54), or -423. The negative sign tells us that this quadratic has two unequal, complex roots, which are:
-(3) ± i√423 -3 ± i√423
n = ------------------- = ------------------
2(2) 4
Answer:

it's option d bro...becoz
x + 10 is the diameter
Step-by-step explanation:
<u>Rule:</u>
When exponents multiply, they're adding.
<u>Multiply:</u>
Option A is correct.
Well we know that:
1-4 stay on the floor,
5-9 it's round up time.
So with that in mind you would round the 9's up and they would round up th 4 to a 5. 5's round up so that would round up the first 4 to a 5.
SO your answer would be 5,000.
