Answer:
SR =3
Step-by-step explanation:
SR + RQ = SQ
2x+23 + x+21 = 14
Combine like terms
3x+44 = 14
Subtract 44 from each side
3x+44-44= 14-44
3x = -30
Divide each side by 3
3x/3 = -30/3
x = -10
SR = 2x+23 = 2(-10)+23 = -20+3 =3
Answer: 3
Step-by-step explanation:
We can start by making an equation.
Since we know the total length of SQ we can add SR + RQ to equal SQ.
The parenthesizes are not necessary but they help for understanding the parts of the equation.
We will remove the parenthesizes and combine like terms.
Now subtract 44 from both sides to cancel it out from the side with x.
Now divide by 3 to isolate x.
So x = -10.
Now we can plug in the value of x into SR.
Solve
So SR = 3

Answer:
Like Terms
Definition:
Terms that have identical variable parts (same variable(s) and same exponent(s)). When simplifying using addition and subtraction, you combine “like terms” by keeping the "like term" and adding or subtracting the numerical coefficients.
