We know that
step 1
find the original area of rectangle
Area of rectangle=L*W-----> 10*12----> 120 ft²
step 2
find the new area
if <span>increase the area by 50%
so
the new area=120*1.5----> 180 ft</span>²
step 3
find the new dimensions
(10+x) ft x (12+x) ft
new area=(10+x)*(12+x)
180=(10+x)*(12+x)----> 180=120+10x+12x+x²----> 180=x²+22x+120
x²+22x-60=0
using a graph tool-----> to resolve the second order equation
see the attached figure
the solution is
x=2.454 ft
the answer
the equation is
Answer:triangle Explanation:the three corners all make triangles individually and if you put them to together they will create a larger triangle
Answer:
60 seconds
Step-by-step explanation:
Hi!
After she goes forward 5 feet (4 seconds), and the backwards 3 feet (another 4 seconds), the total distance forward she travelled is 2 feet. Then, she moved forward 2 feet in 8 seconds.
Then, as this is repeated, she moves forward 2 feet every 8 seconds. After 7 repetitions she travelled 14 feet, and 56 seconds elapsed. Then she goes forward 5 feet in 4 seconds, and she finaly reaches the end of the hallway
(14 +5 > 15)
So, in 60 seconds she reached the end of the hallway.
The answer would be 4 weeks and the total be $280. If you plug in 4 for Carly, you get $280 and if you plug in 4 for Janiya, you also get $280
