Answer: James has 36 sneakers.

Expression: 3 * 12

Step-by-step explanation:

If James has 3 times as much as Kevin then the amount that he has should equal 3 when divided by 12.

Assume x is equal to how much james has.

3 = x/12

Multiply 12 on both sides

x = 36

Find the value for the variable that makes the expression undifined.<br> X2 -9<br> X2-7x+10
Anika [276]

an equation is undefined, when its denominator is 0, or turns to 0, because we can't divide anything by 0.

so let's simply set the denominator of this one = 0.


\bf x^2-7x+10=0\implies (x-2)(x-5)=0\implies x= \begin{cases} 2\\ 5 \end{cases} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{(2)^2-9}{(2)^2-7(2)+10}\implies \cfrac{-5}{-10+10}\implies \cfrac{-5}{0}\leftarrow und efined \\\\\\ \cfrac{(5)^2-9}{(5)^2-7(5)+10}\implies \cfrac{16}{-10+10}\implies \cfrac{16}{0}\leftarrow und efined

Find m∠A.<br> A. 32<br> B. 26<br> C. 27<br> D. 30
krok68 [10]
<h3>Answer: B. 26</h3>

============================================

Use law of cosines to find angle A

a^2 = b^2 + c^2 - 2*b*c*cos(A)

9^2 = 6^2 + 14^2 - 2*6*14*cos(A)

81 = 36 + 196 - 168*cos(A)

81 = 232 - 168*cos(A)

81 - 232  = -168*cos(A)

-151  = -168*cos(A)

-168*cos(A) = -151

cos(A) = (-151)/(-168)

cos(A) = 0.8988095

A = arccos(0.8988095)

A = 25.9979801

A = 26 degrees approximately
