Answer:
The dimensions of rectangle are
Length: 15 meters
Breadth: 12 meters
Step-by-step explanation:
Let
x ----> the original length of rectangle
y ---> the original breadth of rectangle
The area of rectangle is
1) The area of a rectangle reduces by 20 m2, if its length is increased by I m and the breadth is reduced by 2 m
Remember that
substitute
-----> equation A
2) The area increases by 12 m², if the length is reduced by 3 m and the breadth is increased by 4 m.
Remember that
substitute
-----> equation B
Solve the system of equations A and B by substitution
substitute equation A in equation B
solve for x
Find the value of y
therefore
The dimensions of rectangle are
Length: 15 meters
Breadth: 12 meters
Answer:
I do not agree with Scott.
Step-by-step explanation:
22% *of* 160 --- meaning 22% times 160 --- is 35.2 so it's in fact approximately 35.
Answer:
=-110
Step-by-step explanation:

<span>2+3(x-3)+1-5(2-x)
The first thing we must do is distribute...
2 + 3x - 9 + 1 - 10 + 5x
Then we must combine like terms. We can combine terms with an x together and we can combine terms without an x together.
2 - 9 + 1 - 10 = -16
3x + 5x = 8x
So our simplified expression is C. 8x - 16</span>
Answer:

Explain
From the list of given options, option D answers the question.
This is because, the expression above involves distributive property and only option D correctly states that.
A distributive property is:
In this case:
and
So:
Substitute values for a, b and c
