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
All you do is multiply 24 and 16 by 1/4
6 - 4x
There are 13 cards of each suit.
Picking a heart would be 13/52 which reduces to 1/4
Then replacing the card and picking a club would be the same : 1/4
Picking a heart then a club would be 1/4 x 1/4 = 1/16
Answer: 1/16
Answer:
13 weeks.
Step-by-step explanation:
equation type is y=mx+b
b=60
m=5
x=how many weeks
y=125
125=5x+60
-60
125-60=65
65=5x
65/5=13
Answer: -47
Step-by-step explanation:
6p^2-(3p^2+2q^2)=
6(1)^2-(3(1)^2+2(5)^2)=
6-(3+2*25)=
6-(3+50)=
6-53=-47
