The equivalent expression of 2b + 4 is 2(b + 2) .
<h3>What is an equivalent expression?</h3>
Equivalent expressions are expressions that work the same even though
they look different.
In other words, two expressions are said to be equivalent if they have the
same value irrespective of the value of the variable(s) in them.
If two algebraic expressions are equivalent, then the two expressions
have the same value when we plug in the same value for the variable.
Therefore, let's find the equivalent expression of 2b + 4.
Hence, using common factor,
2b + 4 = 2(b + 2)
Therefore, the equivalent of 2b + 4 is 2(b + 2)

Answer:
tan(Q) is Option C : 1
Step-by-step explanation:
Given:
To Find:
tan(Q)
Solution:
Step 1: Finding the angle QPR
We know that the 
and 
are supplementary angles. Then the sum of and must be equal to 180 degrees
So
From the figure
Step 2: Finding the angle PQR
Now we also know that The "Triangle Sum Theorem states" that the three interior angles of any triangle add up to 180 degrees.
According to this theorem , In the figure,
the sum of all the interior angles in the triangle PQR
Substituting the known values
Step 3: Finding the tan(Q)
We now Know that 
Answer:
a.
x + y = 60
x = y + 30
b.
substitution:
(y + 30) = y = 60
2y + 30 = 60
2y = 30
y = 15
15 minutes for freehand
c.
No, because if he spends 40 minutes on the treadmill, he would have spent 10 minutes for freehand exercises. His total time in the gym would be 50 minutes, not 60.
