The triangles in the image are similar. Solve for x. A) 7 B) 6 C) 10 D) 5

Natalka [10]

ANSWER

A) 7

EXPLANATION

The given triangles are similar

Hence the corresponding sides are in the same proportion.

$\frac{3x + 4}{30} = \frac{30}{36}$

Simplify the right hand side:

$\frac{3x + 4}{30} = \frac{5}{6}$

Cross multiply;

6(3x+4)=5×30

Expand

18x+24=180

18x=150-24

18x=126

$x = \frac{126}{18} = 7$

Let Upper A equals left bracket Start 2 By 2 Matrix 1st Row 1st Column negative 2 2nd Column 4 2nd Row 1st Column 1 2nd Column 3

Yuliya22 [10]

Answer: a) AB = $\left[\begin{array}{ccc}-14&26\\-11&22\end{array}\right]$ ; b) $\left[\begin{array}{ccc}5&-5\\13&9\end{array}\right]$ ; c) No, they are different; d) No, they are never the same;

Step-by-step explanation:

a) A = $\left[\begin{array}{ccc}-2&4\\1&3\end{array}\right]$ , B = $\left[\begin{array}{ccc}-2&1\\-3&7\end{array}\right]$ . This multiplication is possible, because matrix A has 2 columns and matrix B has 2 rows. When those value are equal, the multiplication is possible.

AB = $\left[\begin{array}{ccc}-2&4\\1&3\end{array}\right]$ . $\left[\begin{array}{ccc}-2&1\\-3&7\end{array}\right]$ = $\left[\begin{array}{ccc}-14&26\\-11&22\end{array}\right]$

b) BA = $\left[\begin{array}{ccc}-2&1\\-3&7\end{array}\right]$ . $\left[\begin{array}{ccc}-2&4\\1&3\end{array}\right]$ = $\left[\begin{array}{ccc}5&-5\\13&9\end{array}\right]$

c) As, we can see, parts a and b are differents.

d) With matrices, multiplication is not commutative, which means AB≠BA
