−35

The rational number −35 is equal to
plese dont be too sart and give the answer first then explain it

84

Step-by-step explanation:

So the number of divisors is:

σ=(1+na1)(1+na2)...(1+nak)

Suppose that the target number n has 4 distinct prime factors. The smallest such number is n=2×3×5×7=210. The number of divisors of nn is (1+210)4 which is obviously greater than 106. There is no need to consider any other number n with 4 or more disitnct prime factors and we already know that the solution is not greater than 210.

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
