Answer:
x = 7.3
Step-by-step explanation:
-2x + x-4 = 18
First, Combine Like Terms
-3x + (-4) = 18
Then, do Inverse Operations
-3x + -4 = 18
+ 4 +4
Cancel out the -4 +4 because it will equal zero and won't matter to the equation
-3x = 22
Do Inverse Operations again. In this case, you will divide.
-3x = 22
-3x/-3 = 22/-3
Cancel out the -3x/-3
22/-3 = x
7.3 = x
Because 3 2/4 would be the answer when you subtract it and most teachers and/or tests want you to simplify the answer which would be 1/2 because you would divide the numerator and denominator by 2.
Solution/Answer : 4
Solution: the first you do is multiply the last two parentheses to get -10xy
Now we are left with ( -2/5x)(-10xy)
Then we multiply that out into
(-2*-10)/5*x^2y = 20/5x^2y =
4x^2y
The coefficient in this case would be four. (In case you were confused about what a coefficient actually is, it’s the number you multiply a variable by)
Hopes this helps :)
Answer: The answer is Yes. A square is a rectangle because it possesses all the properties of a rectangle. These properties are: Interior angles measure 90∘ each.
Explanation:
Definition of a Rectangle:
A 4-sided flat shape with straight sides where all interior angles are right angles (90°).
Also, opposite sides are parallel and of equal length.
Definition of a Square:
A 4-sided flat shape with straight sides where all interior angles are right angles (90°).
Also, all sides have equal length
As you can see the first part of the definition of a square and rectangle are the same.
However, a square is a special case of a rectangle.
When all 4 sides of a rectangle are equal then the rectangle is a square.
So, a rectangle can also sometimes be a square.
