Answer: In your problem, you said that they are squared. However, it is not written as squared. We just have to multiply them.
We can use the FOIL method.
(3b - 5c)(3x + 5y)
6bx + 15by - 10cx - 25cy
There are no like terms, so that expression is our final answer.
Use pythagora's theorem to test if it is a right triangle
c^2 = a^2 + b^2
65^2 = 52^2 + 43^2
4225 = 2704 + 1849
4225 =/= 4553
therefore it is not a right triangle as it does not comply to pythagora's theorem
This expression is already simplified.
Answer:
11th month which is November
Step-by-step explanation:
1860 + 45(m - 1) = 2310
1860 + 45m - 45 = 2310
1815 + 45m = 2310
45m = 495
m = 11
Given:
In parallelogram ABCD, two of its vertices are A(-4,0) and B(0,3).
To find:
The equation that represents a line that contain CD.
Solution:
We have,
A(-4,0) and B(0,3)
Slope of AB is



The slope of line AB is
.
Opposite sides of a parallelogram are parallel and slopes of parallel lines are equal.
In parallelogram ABCD, AB and CD are opposite sides. So, their slopes must be equal.
Slope of line AB = Slope of line CD = 
The slope intercept form of a line is

Where, m is slope and b is y-intercept.
Slope of line CD is
, it means the line must be of the form

Coefficient of x is
only in option a.
Therefore, the correct option is a.
