Answer:

Step-by-step explanation:

a1 = -5

a2 = -3

a3 = -1

and so on

So since we start with -5 it will be -5+ something.

each time you add 2, but since the first one doesnt add anything we want n-1 times 2 so that leaves us with -5+(n-1)2

Let p: A triangle is acute.

zvonat [6]

An equilateral triangle has all three angles as 60 degrees, this also makes the triangle an acute triangle.

This makes both p and q true.

P V q is also true, the V means “or”, so if either p or q is true the statement is true

p ∧ q means and, since both p and q are true, this is also true.

The left and right arrows means “implies”, so this is true if and only

if the p is false or q is true (the sentence ((~p)vq) is true). Since Both p and q are true both the left and right arrows are true

The last one means equal and is true if both p and q are the same, which they are, so this is also true,.

All the given statements are true.,

-2-(+7) is the same thing at -2-7 which is -9

$-3 \frac{2}{7} -(- \frac{5}{7} )$ is the same thing as $(-3 \frac{2}{7}) + (\frac{5}{7})$ which is $- \frac{18}{7}$ or $-2 \frac{4}{7}$

Last but not least the last one is the Associative Property based on definition listed below :)
Associative Property:<span> When three or more numbers are added, the sum is the same regardless of the grouping of the addends. For example (2 + 3) + 4 = 2 + (3 + 4)</span>
