(8x^2 + 3) + (4x^2 + 5x + 4) i need this combined

12x^2 +5x + 7

Step-by-step explanation:

You just need to combine like terms. you can combine 8x^2 and 4x^2 since they both have the same x^2 value. There is nothing to combine 5x with, so it remains 5x. Finally, you add the two integers, 4 and 7. This gives you the final answer, which is a quadratic equation.

12x^2+5x+7

Step-by-step explanation:

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
