Hey there!
We know that perimeter is all the sides added up.
70= 2w+2L <== this is the basic equation
We know that the rectangles length is three times as long as it is wide.
So, you know that is is three times the length of the width. So, put 3 times w in as length and times that by two since there are two length sides, and keep width the same. 2w because there are two width sides. Then, solve.
70=2(3w)+2w
70= 6w+2w
70=8w
w=8.75
We can check this by plugging it in to our first equation and seeing if it works. First, we need to multiply 8.75 by 3 to get the value for length.
8.75*3= 26.25
2(26.25)+2(8.75)= 70 <=== it works!
So, the length is 26.25 cm and the width is 8.75 cm.
I hope this helps!

Answer:
It has 0 distinct real number zeros. The function does not touch the x-axis
Answer: 5 years
Step-by-step explanation:
Using same formula as for Compound Interest:
12700 = 23400 (1-.115)^t
12700 = 23400 x 0.885^t
0.885^t = 127/234
Convert decimal into fraction:
177/200^t = 127/234
Take logarithm of both sides of thr equation:
t = log 177/200 (127/234)
t = 5.00242
Damin numba of songs let it be d
moesha will have the variable m rep her number of songs
m=2d+17
If damian has 5 songs then d= 5.
im going to use a bracket around 5 where d should be if it is confusing:
m=2(5)+17
2*5=10
10+17=27
m=27
moeshas got 27 songs in her library
