Answer:

Step-by-step explanation:

You can't get a rational result. √2 does not go away.

√98  = √(49 * 2) = √7 * 7 * 2 = 7√2

6*√72 = 6 * √(2 * 2 * 2 * 3*3) = 6 * 2 * 3 √2 = 36√2

1/2 * 7√2 - 6*6*√2

√2 (3.5 - 36)

√2 * (-32.5) or

-32.5 * √2

Sunny_sXe [5.5K]
Hello DestinyKiara99 o/
We can solve this equation using the quadratic formula
Check it out...

x² + 6x - 24 = 0       

Δ = 6² - 4.1.(-24)
Δ = 36 + 96
Δ = 132

x = -6 +/- √132    x' = -3 + √33
<span>      --------------   /

                            x'' = - 3 - </span>√33
The correct answer is the letter D
I hope this help =)

The divisor of 0.004 is almost zero. What does this tell you about the quotient?
nasty-shy [4]

Answer:

  Its magnitude will be larger than 0.004.

Step-by-step explanation:

When a divisor is less than 1, the quotient will be greater than the dividend.

When the divisor is "almost zero", the quotient will be much greater than the dividend. Here, the dividend may be considered to be "almost zero", so we cannot say anything about the actual quotient except to say its magnitude will be greater than the dividend.

_____

The dividend is positive, so the quotient will have the same sign as the divisor. (Negative divisors can be "almost zero," too.)
