Answer:
5(d - 2) = 45
Step-by-step explanation:
Solve the given equation for d
3(d + 1) = 4(d - 2) ← distribute parenthesis on both sides
3d + 3 = 4d - 8 ( subtract 3d from both sides )
3 = d - 8 ( add 8 to both sides )
11 = d
Then
5(d - 2) = 5(11 - 2) = 5(9) = 45

Explanation:

let's break down the expression to get the final result:

Answer:
the answer is x=6 for this question
Answer:
See Below.
Step-by-step explanation:
Problem 1)
We want to simplify:

First, let's factor the denominators of each term. For the second term, we can use the difference of two squares. Hence:

Now, create a common denominator. To do this, we can multiply the first term by (<em>a</em> + 1) and the second term by (<em>a</em> + 2). Hence:

Add the fractions:

Factor:

Simplify:

We can expand. Therefore:

Problem 2)
We want to simplify:

Again, let's create a common denominator. First, let's factor out a negative from the second term:

Now to create a common denominator, we can multiply the first term by (<em>a</em> - <em>c</em>) and the second term by (<em>a</em> - <em>b</em>). Hence:

Subtract the fractions:

Distribute and simplify:

Cancel. Hence:
