Answer 1

Respuesta:

Explicación paso a paso:

e) 12+{15-(28-6b-12a)+2}-18ab+3b+15ab+5a=

=12+15+−28+6b+12a+2+−18ab+3b+15ab+5a  

=12+15+−28+6b+12a+2+−18ab+3b+15ab+5a

=(−18ab+15ab)+(12a+5a)+(6b+3b)+(12+15+−28+2)

=−3ab+17a+9b+1

f) {(-2)(-5)(-4)+20+(-5)}+{(-2)+(-10)-(-3+2)}=

=(10)(−4)+20−5−2−10−(−3+2)

=−40+20−5−2−10−(−3+2)

=−20−5−2−10−(−3+2)

=−25−2−10−(−3+2)

=−25+−12−(−3+2)

=−25−12−(−1)

=−25+−11

=−36

g) {15-(-3)-4}+{-8+2-5-11}+(-2-1)

=18−4−8+2−5−11−2−1

=14−8+2−5−11−2−1

=14+−6−5−11−2−1

=14+−11−11−2−1

=14+−22−2−1

=−8−2−1

=−8+−3

=−11
