Solve for A<br> 3(4A + 4) = 3A + 8A + 1 + 8
kvasek [131]

Answer:

a=−3

Step-by-step explanation:

Let's solve your equation step-by-step.

3(4a+4)=3a+8a+1+8

Step 1: Simplify both sides of the equation.

3(4a+4)=3a+8a+1+8

(3)(4a)+(3)(4)=3a+8a+1+8(Distribute)

12a+12=3a+8a+1+8

12a+12=(3a+8a)+(1+8)(Combine Like Terms)

12a+12=11a+9

12a+12=11a+9

Step 2: Subtract 11a from both sides.

12a+12−11a=11a+9−11a

a+12=9

Step 3: Subtract 12 from both sides.

a+12−12=9−12

a=−3

Answer:

a=−3

I need help please ASAP thank you

Answer:

The products of AB and BA is given by

AB=\left[\begin{array}{cc}21&-6\\ 9&3\end{array}\right]

BA=\left[\begin{array}{cc}9&-1\\-18&15\end{array}\right]

Step-by-step explanation:

Given the matrices A=\left[\begin{array}{cc}6&-5\\-3&-4\end{array}\right] and

B=\left[\begin{array}{cc}1&-1\\-3&0\end{array}\right]

To find the product AB and BA

AB=\left[\begin{array}{cc}6&-5\\-3&-4\end{array}\right] \left[\begin{array}{cc}1 & -1\\-3 &0\end{array}\right]

=\left[\begin{array}{cc}6+15& -6+0\\-3+12&3-0\end{array}\right]

Therefore the product of AB is

AB=\left[\begin{array}{cc}21&-6\\ 9&3\end{array}\right]

BA=\left[\begin{array}{cc}1&-1\\-3&0\end{array}\right] \left[\begin{array}{cc}6&-5\\-3&-4\end{array}\right]

=\left[\begin{array}{cc}6+3& -5+4\\-18+0&15+0\end{array}\right]

Therefore the product of BA is

BA=\left[\begin{array}{cc}9&-1\\-18&15\end{array}\right]

The products of AB and BA is given by

AB=\left[\begin{array}{cc}21&-6\\ 9&3\end{array}\right]

BA=\left[\begin{array}{cc}9&-1\\-18&15\end{array}\right]
