Similar triangles are triangles that have the same interior angles and the corresponding sides are proportional, that is, for triangles STU and XYZ we have the proportion:

\frac{ST}{XY}=\frac{TU}{YZ}=\frac{SU}{XZ}

The corresponding sides are congruent only if the proportion rate is 1, but that is not always true and it's not necessary.

Therefore the correct option is B: False

If the corresponding sides are congruent, the triangles are congruent.

Answer:

230 - 151 + 180 + (43 - 12) = 290

Step-by-step explanation:

Use PEMDAS.

Evaluate the expression in the parentheses:

230 - 151 + 180 + (43 - 12)

43 - 12 = 31

230 - 151 + 180 + 31

Add and Subtract From Left to Right:

230 - 151 + 180 + 31

79 + 180 + 31

259 + 31

290

Nutka1998 [239]

Answer:

The null hypothesis   H_o :  \mu =  31

The alternative hypothesis H_a :  \mu >  31

Step-by-step explanation:

From the question we are told that

  The population mean is  \mu =  31 \  miles / gallon

Generally

   The null hypothesis is that the company's  new sedan, the Libra, will have an average of   \mu =  31 \  miles / gallon

This mathematically  represented as

The null hypothesis   H_o :  \mu =  31

   The alternative hypothesis is that the company's  new sedan, the Libra, will have an average better than   \mu =  31 \  miles / gallon

This mathematically  represented as

     The alternative hypothesis H_a :  \mu >  31

barxatty [35]

Step-by-step explanation:

3 {x}^{2}  + 12x = 15 \\ 3 ({x}^{2}  + 4x) = 15 \\  {x}^{2}  + 4x = 5 \\  {x}^{2}  + 4x  = 5 \\  {x}^{2}  + 4x + 4 = 5 + 4 \\ {x}^{2}  + 4x + 4 = 9 \\ {x}^{2}  + 4x +  {2}^{2}  =  {3}^{2}  \\ \red{ \bold{ (x + 2)^{2}   =  {3}^{2}}}  \\
