The length of the rectangle is 8cm longer than the width.
l=w+8
If the length of the original rectangle is increased by 6cm and the width is increased by 3cm the perimeter is 76cm.
p=76=((l+6)+(w+3))*2=(l+6+w+3)*2=(l+w+9)*2
to solve this substitute l=w+8 into the p= equation:
p=76=((w+8)+w+9)*2=
76=(2w+17)*2
76=4w+34
42=4w
10.5=w
l=w+8=10.5+8=18.5

Hello!</h2>
The answer is:
Answer: 34
Units: Joules
<h2>
Why?</h2>
The kinetic energy is the work needed to accelerate an object to a determined speed.
The kinetic energy can be calculated using the following equation:
Where,
m, is the mass of the object.
v, is the speed of the object.
So, we are given the information:
Then, substituting and calculating we have:
Have a nice day!
Answer:
1) False. 2) False.
Step-by-step explanation:
1) False. 2) False.
1) is false because it says, "A total of 40 students can type from 0-59 words per minute." 0-14w=5s, 15-29w=10s, 10-44w=14s, and 45-59w=20s. w= words per minutes s= number of students (BTW) 5+10+14+20=54 not 40
2) is false because it says, "The number of students who typed 45-59 words per minute is equal to the number of students who typed 15-39 and 0-14."
45-59w=20s
15-39w=10s and 0-14w=5s
10s+5s=15s
20s>15s
