The answer is $- 14 r + 60$ $-14r+60$ .

See the explanation for the process.

Simplify:

$- 6 (5 r - 6) + 4 (6 + 4 r)$ $-6(5r-6)+4(6+4r)$

First expand each term using the distributive property: $a (b + c) = a b + a c$ $a(b+c)=ab+ac$ .

$- 30 r + 36 + 24 + 16 r$ $-30r+36+24+16r$

Gather like terms.

$(- 30 r + 16 r) + (36 + 24)$ $(-30r+16r)+(36+24)$

Simplify.

$- 14 r + 60$ $-14r+60$
