Please answer number 14<br> I already tried but don’t understand

Answer:
$< abc = < ebc \\ < acb = < ecd \\ if \: two \: angles \: in \: the \:two \: different \: triangles \: are \: equal \: then \: the \: third \: angle \: in \: the \: triangle\: must \: be \: equal. \\ using \: pythogres \: theorum \\ ab = \sqrt( ac ^{2} - bc^{2} )\\ = \sqrt (15 ^{2} - 12 ^{2}) \\ = \sqrt( 225 - 144 )\\ = \sqrt(81) \\ ab = 9 \\ sides \: of \: similar \: triangle \: are \: propotional \\ ac \div ec = dc \div bc \\ 15 \div x = 12 \div 6\\ x = 15 \times 6\div 12\\ x = 15 \div 2 \\ x = 7.5 \\ so \: ec \: = 7.5 \\ you \: can \: check \: this \: by \: applying \: pythogores \: theorum. \\ i \: hope \: this \: helps$

Recursive formula for 26, 24, 22, 20

dexar [7]

Answer:

a_n = 28-2n

Step-by-step explanation:

Given sequence is:

26,24,22,20

We can see that the difference between consecutive terms is same so the sequence is an arithmetic sequence

The standard formula for arithmetic sequence is:

$a_n = a_1+(n-1)d$

Here,

a_n is the nth term

a_1 is the first term

and d is the common difference

So,

d = 24-26

= -2

a_1 = 26

Putting the values of d and a_1

$a_n = 26 + (n-1)(-2)\\a_n = 26-2n+2\\a_n = 28-2n$

Hence, the recursive formula for given sequence is: a_n = 28-2n ..

Yolanda has 2 granola bars. Each serving is of a bar of granola.

RSB [31]

The model of the granola bars is an illustration of <em>ratios and proportions</em>.

The model that shows the total serving is model A

The given parameters are:

$\mathbf{Bars = 2}$

$\mathbf{Serving = \frac{2}{5}}$

So, the number of servings in both bars is:

$\mathbf{Total = Bars \div Serving}$

Substitute 2 for Bars and 2/5 for Servings

$\mathbf{Total = 2 \div \frac{2}{5}}$

Express as multiplication

$\mathbf{Total = 2 \times \frac{5}{2}}$

$\mathbf{Total = \frac{10}{2}}$

$\mathbf{Total = 5}$

The total number of servings is 5

The model that shows a total serving of 5 is model A (see attachment)
