\huge \boxed{\mathbb{QUESTION} \downarrow}

  • Simplify ⇨ 4 (2m - 6) + 3 (3 + 5m)

\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}

\sf \: 4 \left( 2m-6  \right)  +3 \left( 3+5m  \right)

Use the distributive property to multiply 4 by 2m-6.

\sf8m-24+3\left(3+5m\right)

Use the distributive property to multiply 3 by 3+5m.

\sf \: 8m-24+9+15m

Add -24 and 9 to get -15.

\sf \: 8m-15+15m

Combine 8m and 15m to get 23m.

\boxed{ \boxed{ \bf \: 23m-15 }}

Answer:

 B.  4200

Step-by-step explanation:

A suitable calculator can add the terms for you. (See attached)

__

The first term is 69, and the common difference is 75-69 = 6. The general term is ...

  an = a1 +d(n -1)

  an = 69 +6(n -1)

Then the 28th term is ...

  a28 = 69 +6(27) = 231

The average term is (a28 +a1)/2 = (231 +69)/2 = 150.

The sum is the number of terms multiplied by the average term:

  sum = 28×150= 4200
