Answer: 5y + x
Step-by-step explanation: As you first step to this problem, change all your minus signs to plus negatives.
To simplify, we can only combine what are called our like terms and in this problem, we have one y-term and we have a pair of like terms in our x-terms.
So let's start by combining our y-terms.
13y + -7y simplifies to 5y.
Now we have one x-term so we have 5y + x.
Answer:
x = √(28), or x = 5.292
Step-by-step explanation:
First you distribute the square to the values inside of the parentheses. so it ends up looking like this
5(x^2 - 25) - 9 = 6
add 9 to both sides
so its 5(x^2 - 25) = 15
Then distribute the multiplication of 5 to the contents within the parentheses
so it would be 5x^2 - 125 = 15
add 125 to both sides
you get 5x^2 = 140
divide by 5 on both sides
you get x^2=28
then, take the square root of both sides to reverse the square
√(x^2)=√(28)
and in the end you get x=5.292
but √(28) will probably be fine if your teacher doesn't want u to solve for that kind of stuff.
Answer:
I believe that those triangles are not similar
Step-by-step explanation:
5 is 1.666 of 3
20/3=6.667
1.666 does not equal 6.667
if I did that correctly, they are not similar
Hope this helps!
Answer: (-1,2)
Step-by-step explanation:
The following statements are true for a parallelogram that must be a rectangle.
parallelogram with a right angle
parallelogram with congruent diagonals
A Parallelogram is a flat shape with opposite sides parallel and equal in length. Squares, rectangles and rhombuses are all parallelograms but with slight differences.
