Answer: Bottom left corner

Let n be an odd number. Because 4n is a multiple of 2, it is an even number.

============================================

Explanation:

The square has a side length of n, so its perimeter is 4n since n+n+n+n = 4n.

We can rewrite 4n as 2*2n = 2m where m = 2n is an integer. Any number in the form 2*(some integer) is always even. Even numbers always have 2 as a factor.

So whenever it comes to proving something is even, the ultimate goal is to get it into the form 2*(some integer). If we can do this, then the number is even. If not, then the number is odd.

8. Solve x/10 = –7. A. x = –0.7 B. x= –17 C. x = –70 D. x = 3
ANEK [815]
For this problem, I believe you would just have to plug in for x.

For example, -17 divided by 10 and so on.

The answer should be C, -70. -70 divided by 10 equals -7.

5=1/2x - 3 please help me out
liq [111]

Answer:

x = 16

Step-by-step explanation:

5 = 1/2(x) - 3

Add 3 to both sides.

8 = 1/2(x)

Rewrite for clarity.

1/2(x) = 8

x/2 = 8

Multiply both sides by 2.

x = 16.

Proof:

5 = 1/2(x) - 3

Substitute variable.

5 = 1/2(16) - 3

Multiply 1/2 and 16.

5 = 8 - 3

Subtract 3 from 8.

5 = 5

Round 202.366 to the nearest hundredth
GuDViN [60]
Hello there,

202.366 to the nearest hundredth would be 202.37.

So what I did was I look at the 366 in the problem.

We want to round the to the nearest hundredth.

So what we would do it notice how the 66 in over 50.

The rule is if it's over 50, we round it to the nearest.

So your answer would be 202.37.

Hope this helps.
