Perimeter: P=24 ftLenght: LWidth: W
The length is 2 ft longer than the width:(1) L= W+2 ft
Perimeter: P=2(W+L)P=24 ft2(W+L)=24 ftDividing both sides of the equation by 2:2(W+L)/2 =(24 ft)/2(2) W+L=12 ft
We have a system of 2 equations and 2 unkowns:(1) L=W+2(2) W+L=12
Using the method of substitution: Replacing L by W+2 in the second equation:(2) W+L=12W+(W+2)=12W+W+2=122W+2=12
Solving foe W2W+2-2=12-22W=10Dividing both sides of the equation by 2:2W/2=10/2W=5
Replacing W by 5 in the first equation:(1) L=W+2L=5+2L=7
Answers:What is the width? 5 ftWhat is the length? 7 ft
Answer:
P=4.1
Step-by-step explanation:
Open the parenthesis on LHS.
7p-63=-34.3
Now isolate the variable.
7p=-34.3+63
7p=28.7
Simply Divide.
p=4.1
Put a 1 under the 4 to make 4/1. it will still be 4. then multiply straight across 9 x 4=36 and 1 x 5=5 so the answer is 36/5.
