Product of polynomials can be done by distribution of multiplication over addition. The product of 
is 
<h3>What is distributive property of multiplication over addition?</h3>
Suppose a, b and c are three numbers. Then we have:
(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)
The product result of the given expression is
It is because when bases are same and there is multiplication, then powers add up, so we have: 
Also, we've
where -ve, +ve are sign of operands and result.
That's why 
Thus,
The product of is

y increases by 8
given y = 4x - 3 then an increase in x of 2 units gives
y = 4(x + 2) - 3 = 4x + 8 - 3 = 4x + 5
change in y = 4x + 5 - (4x - 3) = 4x + 5 - 4x + 3 = 8
Answer
A) 2160 cubic inches
Step by step explanation
Volume of a rectangular prism = length *width*height.
The give figure (stairway) consists of two rectangular prism.
The volume of the first rectangular prism (bigger one) = 12 *10*12
=120*12
1 st prism = 1440 cubic inches
The volume of the rectangular prism 2 (smaller one) = 12*10*6
=120*6
The volume of the rectangular prism 2 = 720 cubic inches
The volume of the concrete stairway = Volume of the prism 1 + Volume of the prism 2
= 1440 + 720
The volume of the concrete stairway = 2160 cubic inches.
Thank you.
The exponential equation for the growth is f(x)=57
where x is the number of days and the population on 21st march is 2069983.5 of microbes.
Given:
Days population
0 57
1 95
5 700
10 8525
We have to form exponential equation which shows the growth of microbes.
We know that exponential equation which shows the sum is as under:
f(x)=P
where r is the rate of growth and x is the number of days, months or years depending on how things grows.
In the question when x=0 population is 57.
f(0)=57
P
=57
P=57
When x=1, population is 95.
f(1)=95
P
=95
57 =95
57=95/----1
when x=5,population is 700.
f(5)=700
P
=700
57=700
57=700/-----2
Equating 1&2
95/=700/
=7.36
=7.36
=
equating both sides
4r=2
r=0.5
put the value of t=21 in the exponential equation
f(21)=57
=57
=57*36315.5
=2069983.5
Hence the population on 21st march is 2069983.5.
