Question

3(5p - 1) - 4(3p - 7)
Also please explain it as well

Answer 1

3p+25 you just have to distribute and then collect like terms

Answer 2

3p + 25

Explanation:

Let's start with the original expression:

3(5p – 1) – 4(3p – 7)

We need to distribute each constant to the binomial they are multiplying, and when we do that, we get:

15p – 3 – 12p + 28

Why did the 28 turn out positive? We multiplied two negative numbers together, –4 and –7 , and multiplying two negatives always gives us a positive product.

Now, let's rewrite the expression to group like terms together:

15p – 3 – 12p + 28 — marked like terms, constants bold, variables underlined

15p – 12p + 28 – 3 — rewrote the expression to group like terms

Finally, we combine each set of like terms together to get our final answer:

3p + 25 — simplifying

Hope this helps you understand the concept! Have a great day!
