The mass of a small virus is 10^-20 kg. The mass of an average human cell is 10^-12 kg. Which of the two has lesser mass? how ma
fredd [130]

For this case we have:

10 ^ {- 20}, we must run the decimal point 20 spaces to the left.

0.00000000000000000010 \ kg

10 ^ {- 12}, we must run the decimal point 12 spaces to the left.

0.000000000010 \ kg

Thus, it is observed that the mass of a small virus is smaller!

We subtract and obtain:

10 ^ {-11}

ANswer:

The mass of a small virus is less!

weqwewe [10]

Answer:

X=1.132589

Step-by-step explanation:

If im correct the answer would be x=1.132589

3

x2−1

−2(x+3)=

5

x+1

3

(x+1)(x−1)

+−2x−6=

5

x+1

Multiply all terms by (x+1)(x-1) and cancel:

3+(−2x−6)(x+1)(x−1)=5(x−1)

−2x3−6x2+2x+9=5x−5(Simplify both sides of the equation)

−2x3−6x2+2x+9−(5x−5)=5x−5−(5x−5)(Subtract 5x-5 from both sides)

−2x3−6x2−3x+14=0

(Use cubic formula)

x=1.132589
