What is (5x^2+x-3)-(-2^3+4)
Answers
5x^2+x−3−(−2x^3+4)
5x^2+x+−3+−1(−2x^3)+(−1)(4)
5x^2+x+−3+2x^3+−4
(2x^3)+(5x^2)+(x)+(−3+−4)
And we're left with 2x^3+5x^2+x−7
distribute invisible -1
5x^2+x-3+2x^3-4
group like terms
2x^3+5x^2+x-3-4
2x^3+5x^2+x-7

Let's assume you mean the greatest even integer is 2x.
That means the other two are 2(x-1) and 2(x-2) so the sum is
S = 2x + 2(x-1) + 2(x-2) = 2x + 2x - 2 + 2x - 4 = 6x - 6
Answer: 6x-6

Answer:
AREAof circle = πr² { r = radius} -----------(1)
Area of circle = 54πm²{given} -----------(2)
from eq(1) & eq(2), we get
=> πr² = 54π
=> r² = 54π/π
=> r² = 54
=> r = √(54) {after taking root both sides
Hence,thevalueofradiusis√(54)m.
