Answer:

2x to the second power +x−10

Step-by-step explanation:

Let's simplify step-by-step.

5x+x2−4−(4x−x2+6)

Distribute the Negative Sign:

=5x+x2−4+−1(4x−x2+6)

=5x+x2+−4+−1(4x)+−1(−x2)+(−1)(6)

=5x+x2+−4+−4x+x2+−6

Combine Like Terms:

=5x+x2+−4+−4x+x2+−6

=(x2+x2)+(5x+−4x)+(−4+−6)

=2x2+x+−10

Triangle ABC has angle measures as shown.
Goshia [24]

Answer:

29 degrees

Step-by-step explanation:

If I read your question correctly, your degree measures were

35, 52, and 3(x+2).

We know that all triangle angles measure up to 180 degrees, so we can add all of the given degree values to 180.

35+52+3(x+2)=180

Now, we can solve for x.

87+3x+6=180

93+3x=180

3x=87

x=29
