Hey there!

3x(x - 2) + 7x - 1

DISTRIBUTE 3x WITHIN the PARENTHESES

= 3x(x) + 3x(-2) + 7x - 1

= 3x^2 - 6x + 7x - 1

COMBINE the LIKE TERMS

= (3x^2) - 6x + 7x - 1

= 3x^2 + 1x - 1

= 3x^2 + x - 1

Therefore, your answer is: “3x^2 + x - 1” OR you could say “3x^2 + 1x - 1” because they are both equivalent to each other

Good luck on your assignment and enjoy your day!

4^5*7^10 RAISED TO SINGLE POWER

<h3>Answer:   4^15</h3>

Explanation:

The rule used is

a^b*a^c = a^(b+c)

Basically you add the exponents. This only applies if the bases are both the same. In this case, they're both 4 so the rule works out.

Using the rule, we get

a^b*a^c = a^(b+c)

4^5*4^10 = 4^(5+10)

4^5*4^10 = 4^15
