Answer: There are 1436 bricks that he will need to make a brick wall.
Step-by-step explanation:
Since we have given that
Dimensions of a brick wall is given by
Length = 14.5 feet
Width = 0.5 feet
Height = 5.5 feet
Dimensions of a brick is given by
Length = 6 inch
Width = 4 inch
Height = 2 inch
We need to find the number of bricks :
So, Number of bricks is given by

Hence, there are 1436 bricks that he will need to make a brick wall.
Answer:
x+9
Step-by-step explanation:
4x³+12x²-72x
=4x(x²+3x-18)
=4x[x²+6x-3x-18]
=4x[x(x+6)-3(x+6)]
=4x(x+6)(x-3)
Answer:
We can find the sum of all the coefficients by substituting all the variables in the expansion with one.
a. u=1,v=1
sum=
=
b.u=1,v=1
sum=
=1
c.u=1,v=1
sum=
=-1
d.u=1,v=1
sum=
=-
e.i=1
sum=
=
f.i=1
sum=
=0
g.i=1
sum=
=
h.i=1
sum=
=
The $25.10 is 108% of the sale price.
$25.10 = 1.08n divide both sides by 1.08 = $23.24
To find the original price we must say that the sale price is 80% of the original price.
So we can write $23.24 = 80% of n or $23.24 = .8n Dividing both side by .8 we get $29.05.
So how can we do both of these in one equation? Here is one way.
($25.10/ 1.08) = .8n (I wrote it as two equation above since it explains it better)
There are other equations that will work too.
