Step-by-step explanation:
The graph is represented graphically by drawing a point for each vertex and drawing an arc between two vertices if they are joined by an edge. If the graph is directed then...
Explanation: 3 x 2 + 10 x + 3 We can Split the Middle Term of this expression to factorise it. In this technique, if we have to factorise an expression like a x 2 + b x + c , we need to think of 2 numbers such that: N 1 ⋅ N 2 = a ⋅ c = 3 ⋅ 3 = 9 and, N 1 + N 2 = b = 10 After trying out a few numbers we get: N 1 = 9 and N 2 = 1 9 ⋅ 1 = 9 , and 9 + ( 1 ) = 10 3 x 2 + 10 x + 3 = 3 x 2 + 9 x + 1 x + 3 = 3 x ( x + 3 ) + 1 ( x + 3 ) ( 3 x + 1 ) ( x + 3 ) is the factorised form for the expression.

Is this a true/false or do you need an actual mathematical answer?
i will edit my this to answer your question.
I'm just not exactly sure what you are asking :-/
After 45 minutes you will have painted 4*45=180 square feet.
so the total number of painted area, y, is:
y=180+x*(3+4) after the 45 minutes
where x is the number of minutes AFTER THE 45 minutes:
if y is 1000 then
1000=180+x*7
820=x*7
x=117.14
so 117 minutes, or one hour and 57 minutes.
The perimeter of a rectangle is expressed as:
P = perimeter
l = length
w = width
P = 2(l + w)
Plug in our values to the formula mentioned above
32 m = 2(l + 5).
Start by dividing each side by 2.
16 = l + 5.
Subtract 5 from each side.
11 = l.
