Answer:
units
Step-by-step explanation:
<u>Skills needed to solve: Order of Operations, Distributive Property, Perimeter Formula, Like Terms</u>
1) To solve this problem, you need to understand the perimeter formula, and that is:
--> 
P = Perimeter
L = Length
W = Width
2) Based on that, we are given that:
(since the length is x)
(since the width is x+3)
3) After that, we substitute in the values:
(with like terms and addition)
so: 
Use distributive property, which is 
get: 
So: 
Hope this helps and have a nice day!! :) :]
First you put 8 on the inside of a house and 5.5 on the outside. Then you take the 5.5 and see how many times it can go in 8 with out going over, in this case its once. So take 5.5 and subtract it under the 8. Since you used up the whole number, you have to put a decimal now, so put a decimal on the right side of the 1 on top of the house. Then, add a 0 next to the 8 and put it next to the answer of 8-5.5, which is 2.5, and now 25, the zero moving the number to the left once. Now you find out how many times 5.5 goes into 25, which is 4, adding that next to the decimal on top of the house. Now again, subtract 22, which is 4 x 5.5, from 25. Then add a zero, making 3, now 30.Now find how many times 5.5 goes into that, and it is 5. This 4 and 5 pattern will go on forever, so over the 45 in your answer 1.45, put a line. Like this __

$ 2000 is invested at 3 % interest and $ 4000 is invested at 8 % interest
<em><u>Solution:</u></em>
Given that, total of $6000 was invested
Let "x" be the amount invested at 3 % interest
Then, (6000 - x) is the amount invested at 8 % interest
Given that,
<em><u>The total yearly interest amounted to $380</u></em>
Then, we can frame a equation as:
<em><u>Solve the above expression for "x"</u></em>
Thus, $ 2000 is invested at 3 % interest
(6000 - x) = 6000 - 2000 = 4000
$ 4000 is invested at 8 % interest
Answer:
-6
Step-by-step explanation:
4(2x+12)=0
8x+48=0
