Collect the terms in a, then the terms in b, getting 6a - 3a + 2b + 5b which simplifies to 3a + 7b. Gettit?

It is an algabraic expession without knowing whether or not 2b and 3a are plus or minus

idont know

4y - 4 + 3a + 7 - 6a - 4 = 4y -1 - 3a

It is 6a + 4

Area: 15ab Perimeter: 2(3a+5b) or as 6a+10b

6a-3

3a + 4b - (-6a) - 3b? There is no equivalent because you did not make it an equality. However you could combine the numbers... 3a + 4b +6a -3b = 9a + 1b

it is 6a

(4, 3)

2a² + 6a

It is equivalent to 53a+44b when simplified

9a + 7b *remember to look and understand the letters!*

4(5b - 6a^2)(5b + 6a^2)

the answer

6a square plus b square

It is 9

6a + 8 = 2(3a + 4)

a2 - 6a + 9 = a2 - 3a - 3a + 9 = a(a - 3) - 3(a - 3) = (a - 3)*(a - 3) = (a - 3)2

13a - 6 + a = 5a + 3 + 3a 13a + a - 5a - 3a = 3 + 6 6a = 9 6a/6 = 9/6 a = 3/2

It is 20a - 5b - 9.

The solution for the value of 3a would be -3. The equation would be 6a + 3(4) = 2.

6a to the second power minus 8ab + 2a

(2a - 3)(3a - 4)

It is: (2a+3)(3a+4) when factored
