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:
504
Step-by-step explanation:
61 multiplied by 25 is equivalent to 61 added to each other 25 times, or 25 added to each other 61 times.
61 * 25 = 1525
Answer:
WE HAVE FIND HOW MUCH MAY TIME BIGGER IS THE VOLUME OF PYRAMID B THAN PYRAMID A.
The answer is 32 times
Step-by-step explanation:
Volume of Pyramid B = 3136 in³
Volume of Pyramid A = ?
We have to find volume of Pyramid A. As Pyramid is a square pyramid, its volume is given as:
where b = base = 7 and h = height = 6. Substitute the values:
Volume of Pyramid A = 98 in³
To find how many time B is bigger than A, divide volume of B by A:
So, volume of Pyramid B is 32 times bigger than volume of Pyramid A

Replacing y in the second equation gives;
5x+2(-3x-2)=15
5x-6x-4=15
-x-4=15
-x=19
x=-19
y=-3(-19)-2
y=57-2
y=55
(-19, 55)
