Answer: 117.5
Explanation: Assuming that after 10 years the lawn mower would have a value of 0. We can evenly divide $470 by the amount of years.
$750/10 = $75
We would then multiply 75*7.5 years to then realize the value lost over that amount of time would be $352.5, subtracting that from the original value of $470 would then be 117.5
Answer:
(3x+1)(x+3) is the factorised form for the expression.
Step-by-step explanation:

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

+
b
x
+
c
, we need to think of 2 numbers such that:
N

⋅
N

=
a
⋅
c
=

=
9
and,
N

+
N

=
b
=

After trying out a few numbers we get:
N

=

and
N

=

=

, and

Area of rectangle = 44m
height = 
area of rectangle = length X breadth
Therefore, width of the rectangle is 12m
Answer:
96
Step-by-step explanation:
Using side b as the base, 4 points makes 3 bases (the space in between). With three bases, you can have 3 bases of 1 segment, 2 bases of 2 segments, and 1 base of 3 segments. This equals 6 bases. Each of these can connect to a point on line a. 6x6=36
Using side a as the base, 6 points makes 5 bases. With 5 bases, you can have 5 bases of 1 segment, 4 bases of 2 segments, 3 bases of 3 segments, 2 bases of 4 segments, and 1 base of 5 segments. This equals 15 bases. Each of these can connect to a point on line b. 15x4=60
36+60=96
