What is the simplest form of 4a + 8b/12<br> Step by step pls

shutvik [7]

Answer:

4a + 2b/3

Step-by-step explanation:

focus on 8b/12 first:

factor 8b/12 by 4 ---> 8b/12 = 4(2)b/4(3) ----> cancel 4 in the denominator and the nominator ---> 8b/12 = 4(2)b/4(3) = 2b/3

then, go back to 4a:

4a is in its simplest form, it can't be factor

therefore, plus 4a and 2b/3 = 4a + 2b/3

4x2 + 8x - 7 - (3x2 - X+9)

Andreas93 [3]

Answer:

Step-by-step explanation:

$4 {x}^{2} + 8x - 7 - (3 {x}^{2} - x + 9)$

When there is a (-) in front of an expression in parentheses, change the sign of each term in the expression:

$4 {x}^{2} + 8x - 7 - 3 {x}^{2} + x - 9$

Collect like terms

$4 {x}^{2} - 3 {x}^{2} + 8x + x - 7 - 9$

${x}^{2} + 9x - 7 - 9$

Calculate

${x}^{2} + 9x - 16$

Hope this helps...

Good luck on your assignment...
