Answer:

81(x + 2y)(x - 2y)

Step-by-step explanation:

81 {x}^{2}  - 324 {y}^{2}  \\  \\  =  {(9x)}^{2}  -  {(18y)}^{2}  \\  \\  = (9x + 18y)(9x - 18y) \\  \\  = 9(x + 2y) \times 9(x - 2y) \\  \\  = 81(x + 2y)(x - 2y)

MaRussiya [10]

Answer:

(a) P(CBM) = 0.07

(b) P(not CBW) = 0.996

(c ) P(neither is color-blind) = 0.926

(d) P=(at least one is color-blind) = 0.074

Step-by-step explanation:

The correct data is  that Approximately 7% of American men and 0.4% of American women are red-green color-blind.

(a) Probability that he is red-green color-blind:

P(CBM) = 0.07

(b) Probability that she is NOT red-green color-blind:

P(not\ CBW) =1- P(CBW)\\P(not\ CBW) = 1 -0.004\\P(not\ CBW) =0.996

(c) Probability that neither are red-green color-blind

P(neither) = P(not\ CBW)*P(not\ CBM) \\P(neither) = 0.996 *(1-0.07)\\P(neither)=0.926

(d) Probability that at least one of them is red-green color-blind

P(at\ least\ one) = 1- P(neither) \\P(at\ least\ one) = 1-0.926\\P(at\ least\ one) = 0.074

Which of these numbers is a solution of the inequality 3x&gt;18?
Delvig [45]
<h3>hello!</h3>

Let's solve this inequality:-

3x<18

Divide both sides by 3:-

x<6

So numbers less than 6 will make this inequality \sf{true}.

<h3>notes:-</h3>

You haven't listed any numbers, so I don't know what options you have,

Please list the numbers in the comments & I will edit my answer :)

Hope everything is clear; if you need any explanation/clarification, kindly let me know, and I'll comment and/or edit my answer :)
