<h3>
Answer: 24</h3>
Explanation:
There are 4 choices for first place, 3 choices for second place, and 2 choices for third place. Overall, there are 4*3*2 = 24 permutations.
Answer:
-15 plus or minus the square root of 65 all over 4 (All over means fraction)
Answer:
d) 10
Step-by-step explanation:
x ÷ 
+ 8 = 13
substitute 10 for x:
⇒ 10 ÷ + 8 = 13
solve:
1) divide 10 by
⇒ 10 ÷ = 5
2) add 8 to 5
⇒ 8 + 5 = 13
Answer:
no
Step-by-step explanation:
ok
The value of the x and y is 12 and -10 respectively, and the provided figure is a parallelogram because the diagonals bisect each other.
<h3>What is parallelogram?</h3>
In two-dimensional geometry, it is a plane shape having four sides, in which two pairs of sides are parallel to each other and equal in length. The sum of all angles in a parallelogram is 360°.
As we know in the parallelogram, the diagonals bisect each other.
Then,
432 = 3x²
x² = 144
x = √144
x = 12
In the parallelogram, the adjacent opposite angles are the same.
∠C+∠B = 240°
= 360 - 240
∠A + ∠D = 120°
∠A = ∠D = 120°/2 = 60
∠D/2 = 60/2 = 3y + 60
3y + 60 = 30
3y = -30
y = -10
From the definition of the parallelogram, the provided figure is a parallelogram.
Thus, the value of the x and y is 12 and -10 respectively and the provided figure is a parallelogram because the diagonals bisect each other.
