Forget about the negative sign. First you have to find a least common denominator. This would be 63. Since we had to multiply 9 by 7 to get 63 we have to multiply the numerator (4) by 7. This gives us a new fraction of 36/63. Since we ha e to multiply 21 by 3 to get 63 we have to multiply 19 by 3. This gives us 57. So now we have 36/63 and 57/63. Then we add the negative sign back in making 57/63 -57/63. Now we add them together. Because one has a negative sign and one is positive the number has to be closer to zero. So the answer is -21/63.

Answer:

106 degrees

Step-by-step explanation:

Sides AB and CD are equal in length and sides AD and BC are parallel to each other. This tells us that angles B and C are equivalent. Knowing this, we can set up the following equation to solve for x:

4x+42=74+2x

Subtract both sides by 42

4x+42-42=74+2x-42\\4x=32+2x

Subtract both sides by 2x

4x-2x=32+2x-2x\\2x=32

Divide both sides by 2

\frac{2x}{2} =\frac{32}{2} \\x=16

Now, to find angle ABC, or angle B, we can plug x back into its expression:

4x+42\\= 4(16)+42\\=64+42\\= 106

Therefore, the measure of angle ABC is 106 degrees.

I hope this helps!

C; 120 because 24x=360 so x=15. Then ABC is 8x, so 8*15=120.
