Answer:
SR = 5
Step-by-step explanation:
We know that the two lines are equal to each other and thus TS + SR = 13
So, we can simply set the two equations of the first line equal to 13:
x + 2 + 2x - 7 = 13
3x - 5 = 13
3x = 18
x = 6
Now we plug in 6 for x in the SR equation:
2 * 6 = 12 - 7 = 5
B. The variable d represents an unknown number. So, 21+d, is equal to 21+an unknown number.
Answer is : 2^(7/6) x^(5/3) y^(1/6)
