Answer:
-1/4
Step-by-step explanation:
<h3>
Answer: (pr + 1)(q + 1)</h3>
===============================================
Work Shown:
Use the factor by grouping method to get the following.
pqr + pr + q + 1
(pqr + pr) + (q + 1)
pr(q + 1) + 1(q + 1)
(pr + 1)(q + 1)
We can use the FOIL rule, distribution, or the box method to expand out (pr+1)(q+1) to get the original expression again. This helps confirm the answer.
X = 5!
4x+1=2x+11
-1 -1 (Subtract 1 from both sides)
4x =2x+10
-2x -2x (Subtract 2x from both sides)
2x = 10
—— ——
2x 2x (Divide both sides by 2x)
X = 5
Answer:
<h2><em><u>
B or the second one</u></em></h2>
Step-by-step explanation:
This is because you have the equation of 2(2/5x + 2).
When you simplify it you have to first do the parenthesis.
So, 2 * 2/5 = 4/5. This is because 2/1 *2/5 is 4/5.
Then you have to do 2*2. This is equal to 4.
Put them together. So it will be.
<h2><u><em>
4/5x + 4.</em></u></h2>
