Simplify the expression by combining like terms: x + 7x

Mathematics

Aneli [31]3 years ago

Answer:

Like terms means that the numbers have the same variable after them or they don't have a variable at all.  It is also important to remember that any letter that doesn't have a number in front of it technically has a 1 in front of it.

For example, x + 3x = 1x +3x.  Then I add the numbers in the front and I get 4x.

If it had been 4x + 7x + 3, my answer would have been 11x +3.  That's because there were a total of 11 x, but the 3 ones weren't x's so I just leave them alone.

The answer is 8x when you simplify because you are adding another x to 7x so it becomes 8x

Please help! need help with geometry work.
lakkis [162]

Answer:

1) Is 90° because that's what the little square in the corner means.

2) Is 60° because if you take everything to the right of the vertical line and add them up, and then subtract the total from 180° you can find the missing angle.

3) Is 30° because if you use what's below the horizontal line and do the same thing as number 4 (add the existing angles together and subtract the total from 180) you can find the missing angle.

4) Is 20° because if you add the existing angles together (40° + 90° + 30°), you'll get 160°, and since the diagonal line that's separating everything from 40° to 30° looks as though it equals 180°, you'd subtract 160° from 180° in order to get the missing angle.

5) Is also 90° because the angle across from it (1) looks to be around the same size.

I solved for each in the following order:

1, 5, 4, 3, 2.

I hope this helps. Also please let me know if I got something wrong or if you still need help :)
