Answer:
length= 24 inches
width= 7 inches
Step-by-step explanation:
Start by writing down what you know.
width= w
length= 3w+3
Then, we can substitute into the perimeter of a rectangle equation, P=2l+2w.
62= 2(3w+3) + 2(w)
62=6w+6+2w
62=8w+6
56=8w
7=w
Now, plug this into our original equations for length and width:
width=7
length= 3(7)+3, so 24
For this I used elimination
X=2
Y=0
Answer:
670,000
Step-by-step explanation:
First of all, it would be easier to write down this problem, wouldn't it? ;)
6 x 6 + 9 ÷ 10^2
According to PEMDAS, we will start off with the exponent part of the equation, since there are no parenthesis.
10^2 = 100
Now, we will multiply 6 x 6, which equals 36.
Then, you will divide 9 by 100, which makes 0.09. Now we can add 0.09 to 36 and see what we get as a final answer.
0.09 + 36 = 36.09
FINAL ANSWER --
36.09
