(-10 x -2) -13=x The biggest part on here is that a negative times a negative is always a positive so you just have to use big enough numbers to get over 7 and then subtract the rest to get to 7 which in this case was 13)

Answer: choice A 1/2

Step-by-step explanation:

Events A and B are independent if the equation P(A∩B) = P(A) · P(B) holds true.

so

1/3=2/3*p(B)

p(B)=1/2

Solve for x. <br>0.71= 1/2(9.8) x^2. ​
Fudgin [204]

Answer: 0.38065

in simpler terms x=±  0.145  =±0.38065

Step-by-step explanation: -490x2+71 = 0  

Subtract  71  from both sides of the equation :  

                     -490x2 = -71

Multiply both sides of the equation by (-1) :  490x2 = 71

Divide both sides of the equation by 490:

                    x2 = 71/490 = 0.145

 

When two things are equal, their square roots are equal. Taking the square root of the two sides of the equation we get:  

                     x  =  ± √ 71/490  

The equation has two real solutions  

These solutions are  x = ±√ 0.145 = ± 0.38065

Answer:

  • 6 ≤ x ≤ 12

Step-by-step explanation:

<u>Area formula</u>

  • A = lw

<u>Applied to the given rectangle, we have</u>

  • A = 1.5*4x = 6x

<u>Since 36 ≤ A ≤ 72, substituting A</u>

  • 36 ≤ 6x ≤ 72
  • 6 ≤ x ≤ 12

It is viable.
