A) 2.9
B) 2.0
C) 5.0
D) 0
E) 6.0
20 divided by 30 times 24 is how you find the answer. The answer is x = 16.
Answer:
Quadratic equation has equal roots
We know that quadratic equation has two equal roots only when the value of discriminant is equal to zero. We know that two roots of quadratic equation are equal only if discriminant is equal to zero.
Step-by-step explanation:
<u>144</u>
So, c must be 144 to make the trinomial a perfect square.
Answer: a 180° rotation about its center
Step-by-step explanation:
<em>A parallelogram has rotational symmetry of order 2.</em>
Thus, rotation transformation maps a parallelogram onto itself 2 times during a rotation of
about its center.
And that is at
and
about its center.
Therefore, a 180° rotation about its center will always map a parallelogram onto itself .
- A figure has<em> rotational symmetry </em>when it can be rotated and it still appears exactly the same.
- The<em> order of rotational symmetry</em> of a shape is the number of times it can be rotated around
and still appear the same.
