For this one I'm going to assume that 4 7a means 4 * 7a...
(8 + 7a) + 4 * 7a =
8 + 7a + 28a =
8 + 35a
If I read it wrong and 4 7a is actually 47a then...
(8 + 7a) + 47a =
8 + 54a =
2(4 + 27a)
Answer:
2 positive * 1 negative = negative
2 negative * 1 positive = positive
Step-by-step explanation:
one positive and 2 negative
(+ * -) * - =
positive times negative = negative * negative = positive
(+ * -) * - = +
now if we change the order by putting parenthesis
+ *( - * -)
negative time negative = positive
+ * (+) = positive
the result is positive
The result does not change because of where we put the parentheses.
- * + * + =
negative times positive = negative
negative * positive= negative
- * + * + = negative
The order does not matter
