Answer:
for b-10 the b=5 and b+10 b=4
Step-by-step explanation:
The mean absolute deviation is 4.8 I believe
2 * 2 * 2 * 2 * 2 * 2 = 64
5 * 5 * 5 * 5 * 5 * 5 = 15625
64 * 15625 = 1,000,000
Answer:
Solution given:
length[l]=3x+7
breadth [b]=2x+3
we have
area of rectangle=l×b=(3x+7)(2x+3)
=6x²+14x+9x+21=6x²+23x+21 units ²
An acre is a surface measure, used in agriculture in several countries.
According to the country and the time, it is equivalent to several surfaces.
We will use the following conversion:
1 acre = 43560 feet ^ 2
Thus:
40 acre = 1,742,400 feet ^ 2
The area of the rectangle is:
1,742,400 = (1,200) * (x)
Clearing the other dimension we have:
x = (1742400) / (1200)
x = 1452 feet
