Answer:
Step-by-step explanation:
You will eliminate y because 3y-3y=0
We have that
x²<span>+2x=17
</span><span>Group
terms that contain the same variable
</span>(x²+2x)=17
<span>Complete
the square. Remember to balance the equation
</span>(x²+2x+1)=17+1
Rewrite as perfect squares
(x+1)²=18
x+1=(+/-)√18
x=(+/-)√18-1
x1=√18-1----> 3.24
x2=-√18-1----> -5.24
the answer is
the option
<span>
4.) 3.24, –5.24</span>
Answer:
This quadrilateral has <u> 2 pairs </u> of parallel sides. Therefore, this quadrilateral is a <u> parallelogram </u>
===========================================
Explanation:
The arrow markers on the segments tell us which sides are parallel to one another. The single arrow segments are one parallel pair, while the double arrow segments are the other parallel pair.
By definition, a parallelogram has two pairs of opposite sides that are parallel. If only one pair of opposite sides were parallel, then we'd be dealing with a trapezoid. A square is special type of parallelogram in which all four sides are the same length, and all four angles are the same measure (all four angles are 90 degrees).
Answer: 23.5
The middle of the set is 12 and 15
So you add them and get 27 then divide by 2 so 23.5
(I think)
