Answer:
<h3>Move all the x terms to one side. Use inverse operations and add 1 5 x 15x 15x to both sides to keep the equation balanced. Solve by working backwards from the order of operations. This means we need to undo the −2 first by adding 2 to both sides of the equation to keep it balanced.</h3>
To simplify this expression, we are going to combine like terms.
First, we can see that we have two terms with the variables being multiplied together,
and
. Together, these add to
, so our expression is now:
We also have two terms with ,
and
. Together, these add to
, so our expression is now:
Our final expression is xy - yz + 5.
Answer:
Yes; Opposite sides are congruent, and diagonals are congruent.
Step-by-step explanation:
we have
we know that
the formula to calculate the distance between two points is equal to
step 1
Find the length of the sides
<u><em>Find the distance AB</em></u>
substitute the values
<u><em>Find the distance BC</em></u>
substitute the values
<u><em>Find the distance CD</em></u>
substitute the values
<u><em>Find the distance AD</em></u>
substitute the values
Compare the length sides
AB=CD
BC=AD
therefore
Opposite sides are congruent
step 2
Find the length of the diagonals
<u><em>Find the distance AC</em></u>
substitute the values
<u><em>Find the distance BD</em></u>
substitute the values
Compare the length of the diagonals
AC=BD
therefore
Diagonals are congruent
The figure is a rectangle, because Opposite sides are congruent, and diagonals are congruent
