Answer:

x=2

bd/ba=be/bc

6/6+4=x+1/x+1+x

6/10=x+1/2x+1

12x+6=10x+10

12X-10X=10-6

2X=4

X=4÷2=2

Answer:

x = 2

Step-by-step explanation:

Basic proportionality theorem,

\frac{AB}{BD}=\frac{CB}{BE}\\

AB = AD + DB = 4+6 = 10

CB = CE + EB = x + x +1 = 2x +1

\frac{10}{6}=\frac{2x+1}{x+1}

Cross multiply

10*(x+1) = 6*(2x+ 1)

10*x + 10*x = 6*2x + 6*1

10x + 10 = 12x + 6

Subtract 10x from both sides

10x + 10 - 10x = 12x + 6 - 10x

10 = 2x + 6

Subtract 6 form both sides

10 - 6 = 2x + 6 - 6

4 = 2x

Divide both sides by 2

4/2 = 2x/2

2  = x

x = 2

I'm pretty sure they're congruent according to the sas postulate but could someone make sure?? thx &lt;3
son4ous [18]

Answer:

The triangles aren't necessarily congruent. SAS postulate is side angle side, which means that the angle that is congruent must be between the two sides that are congruent. DF is congruent to MN, and DG is congruent to MP. This means, that angle D must be congruent to angle M.

However, we only know that D is congruent to P, not M.

These triangles are not necessarily congruent.

The following data are the distances between a sample of 20 retail stores and a large distribution center. The distances are in
sesenic [268]

Answer:

Variance = 1,227.27

Standard deviation = 35.03

Step-by-step explanation:

To calculate these, we use the following formulas:

Mean = (sum of the values) / n

Variance = ((Σ(x - mean)^2) / (n - 1)

Standard deviation = Variance^0.5

Where;

n = number of values = 20

x = each value

Therefore, we have:

Sum of the values = 29 + 32 + 36 + 40 + 58 + 67 + 68 + 69 + 76 + 86 + 87 + 95 + 96 + 96 + 99 + 106 + 112 + 127 + 145 + 150 = 1,674

Mean = 1,674 / 20 = 83.70

Variance = ((29-83.70)^2 + (32-83.70)^2 + (36-83.70)^2 + (40-83.70)^2 + (58-83.70)^2 + (67-83.70)^2 + (68-83.70)^2 + (69-83.70)^2 + (76-83.70)^2 + (86-83.70)^2 + (87-83.70)^2 + (95-83.70)^2 + (96-83.70)^2 + (96-83.70)^2 + (99-83.70)^2 + (106-83.70)^2 + (112-83.70)^2 + (127-83.70)^2 + (145-83.70)^2 + (150-83.70)^2) / (20 - 1) = 23,318.20 / 19 = 1,227.27

Standard deviation = 1,227.27^0.5 = 35.03
