Answer:
The highest common denominator between 80 and 64 is 16. This means no string can be cut longer than 16 inches for them all to have the same length.
Step-by-step explanation:
You have to distribute!
6(x) = 6x and 6(-6)=-36
So now you have 6x-36=-3(-x+3)
Now do the same on the other side.
-3(-x)=3x -3(3)=-9
So now, 6x-36=3x-9
Combine the like terms:
Subtract 3x in both sides.
6x-3x=3x
Now: 3x-36=-9
Add 36 in both sides.
3x=27
Divide by 3 on both sides to get x alone.
3x/3= x 27/3=9
X=9
Answer:
27 + 36 = 63
A. (9 + 3)(9 + 4) = 12 × 13 = 156
B. 9(3 + 4) = 9 × 7 = 63
C. 9 + (3 × 4) = 9 + 12 = 21
D. (9 × 3)(9 × 4) = 27 + 36 = 63
