6 0

Since there are like terms, you can combine them

5a-2a = 3a

So, then you get
3a+9

Then you can factor to get a GCF of 3
3(a+3)

3a + 9

You subtract 2a from 5a, which equals 3a, but 9 is by itself, so it stays the same.

Please Help!!

Answer:

D:) (2,2,) is the Answer

Step-by-step explanation:

Solve the following system:

{X - 2 Y = -2 | (equation 1)

{3 X - 2 Y = 2 | (equation 2)

Swap equation 1 with equation 2:

{3 X - 2 Y = 2 | (equation 1)

{X - 2 Y = -2 | (equation 2)

Subtract 1/3 × (equation 1) from equation 2:

{3 X - 2 Y = 2 | (equation 1)

{0 X - (4 Y)/3 = (-8)/3 | (equation 2)

Multiply equation 2 by -3/4:

{3 X - 2 Y = 2 | (equation 1)

{0 X+Y = 2 | (equation 2)

Add 2 × (equation 2) to equation 1:

{3 X+0 Y = 6 | (equation 1)

{0 X+Y = 2 | (equation 2)

Divide equation 1 by 3:

{X+0 Y = 2 | (equation 1)

{0 X+Y = 2 | (equation 2)

Collect results:

Answer: {X = 2 , Y = 2

What is the product of 4+3i and 4-3i

mash [69]

Use the formula $(a+b)(a-b)=a^2-b^2$ .

$(4+3i)(4-3i)=4^2-(3i)^2=16-9i^2 \\ \\
i^2=-1 \\ \\
16-9i^2=16-9 \times (-1)=16+9=25 \\ \\
\boxed{(4+3i)(4-3i)=25}$
