Natalija [7]

Answer:

a) Distributive Property of Multiplication, b) Prioritizing the multiplication, c) Solving the Parentheses first and Reordering the expression d) Grouping the numbers that cancel each other

Step-by-step explanation:

On these expressions below, we have some ways to proceed with this resolution.

a) Distributive Property on Multiplication made possible the distribution of factor -2 (line 1)

a.\\7*2+4-2(7+3)\\7*2+4-2(7)-2(3)\\7*2-7(2)+4-2(3)\\14-14+4-6=-2\\

b) Prioritizing the multiplication on line 1. By following the PEMDA acronym.

Parentheses, Exponents, Multiplication, Division, Adition.

b.)6*3+3*4-8\:\:line\:1\\18+12-8\\18-8+12=22\\

c) Solve the Parentheses first and Reorder the expression

c.)\\3^2+5(1-3)+4*5+1\:line\: 1\\3^2+4*5+1+5(-2)\:line\:2\\9+20+1-10=20\\

d) Grouping the numbers that cancel each other

d.)\\(8+(-12))+10+2\\8+(-12+10+2)=8+(0)=8\\
