Answer:
length=1.05m
perimeter=2.7m
Step-by-step explanation:
18900 in m^2=1.89 m^2
area=length*width
1.89=length*1.8 m
length=1.89÷1.8
length=1.05 m
perimeter=(l+w) 2
perimeter=(1.05+1.8)2
perimeter=2.85×2
perimeter=2.7 m

Answer:
Option B is correct.
The expression which is equivalent to
is; 
Explanation:
Given the equation:
for all values of n.
The quadratic equation in this form; 
First find two numbers that multiply to give ac and add to give b.
From the given equation;
a =1 , b = 26 and c =88
then,
the two number that multiply to give ac =88 is, 22 or 4
and they add up to give b=26 (i.e 22+4)
Now, rewrite the middle term i.e 26n with 22n and 4n , we have

Now, factor the first two terms and last two terms,

we see that
is common to both terms so, we have;

Therefore, the expression
is equivalent to
Check:
(n+4)(n+22) =
=
[ True]
To solve this problem, we should create an equation using the given information. To do this, we should calculate the slope between the two points as if they were regular points, giving us:
change in y/change in x = (v-4)/(-6-0) = (v-4)/(-6)
Since we know that the slope is 2, we can set our calculated value for the slope of the line for the equation (v-4)/(-6) equal to 2, as shown below:
(v-4)/(-6) = 2
To solve this equation, we should multiply both sides of the equation by -6 to get rid of the denominator on the left side of the equation.
v-4 = -12
Next, we should add 4 to both sides of the equation to get the variable v alone on the left side of the equation, as shown below:
v = -8
Therefore, v =-8 is your answer.
Hope this helps!
