Hey there!

The answer is negative. In multiplication, if one term is negative and one term is positive, then the results will always be negative. For example, 2 x -1= -2. -3 x 4 =-12.

I hope this helps!

Solve for X, will mark brainliest if right
Vitek1552 [10]

Answer:

<u>x = 8</u>

Step-by-step explanation:

The sides are in proportion.

  • \frac{RG}{FG} =\frac{SH}{FH}
  • 40 / 7x + 14 = 44 / 33 + 44
  • 40 / 7x + 14 = 44/77 = 4/7
  • 40(7) = 4(7x + 14)
  • 280 = 28x + 56
  • 10 = x + 2
  • <u>x = 8</u>

"Conservationists have despaired over destruction of tropical rain forest by logging, clearing, and burning." These words begin
krok68 [10]

Answer:

The answer is "(0.461 , 7.206)"

Step-by-step explanation:

In the given question some information is missing, that is data. so, the correct answer to this question can be defined as follows:

UnLogged:

x_1=17.500\\s_1=3.529\\n_1=12

Logged:

x_2=13.667\\ s_2=4.500\\n_2=9\\

formula of std error:

\ std \ error =\sqrt{\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2}}

                =\sqrt{\frac{3.529^2}{12}+\frac{4.500^2}{9}}\\\\=\sqrt{\frac{3.529^2\times 3+4.500^2\times 4}{36}}\\\\=1.8133

Point differential estimation =x_1-x _2

                                              = 17.500-13.667\\=3.833

For 90 percent t= 1.860 Cl & 8 df  

error of margin E = t\times \ std \ error

                             = 1.860 \times 1.8133\\= 3.373

Lower bound =mean difference -E=0.461

Upper bound = mean difference+ E=7.206

In the above 90% confidence interval were the population mean= (0.461 , 7.206)

avanturin [10]

Answer:

The equation is equal to

x^{2}=2x+8

Step-by-step explanation:

Let

x -----> the number

we know that

The equation that represented the problem is equal to

x^{2}=2x+8

x^{2}-2x-8=0

Solve the quadratic equation by graphing

The solution are x=-2 and x=4

see the attached figure

therefore

The number can be -2 or 4
