Answer:
D. 6x^4+3x^3y
Step-by-step explanation:
3x^3(2x+y)
distribute 3x^3
3x^3*2x+3x^3*y
=6x^4+3x^3y
Answer:
$258
Step-by-step explanation:
75% = 0.75 when we divide by 100 to convert a percentage to a decimal
75% of total sales = money donated
Total sales = sales from first show + sales from second show
= 24n+32 + (40n+56)
= 64n + 88
0.75 of (64n+88) = money donated
= 0.75 * (64n+88)
= 48n + 66
substitute 4 for n, as she charges $4 for each bracelet
money donated = 48*4 + 66 = 258
Answer:
B
Step-by-step explanation:
6/16 = 0.375
8/24 = 0.33333...
4/8 = 0.5
6/16 = 0.375
therefore, B is correct
Answer: B. An isosceles triangle has an order 1 rotational symmetry because it does not have all congruent angles. dd
Step-by-step explanation:
An isosceles is a triangle that has two sides of equal length.
The isosceles theorem says that the angles opposite to the equal sides of a triangle are equal.
Thus, it also has two equal angles and one non equal angle. Thus, it does not have all congruent angles.
- The order of rotational symmetry of a figure is the number of times we rotate up to 360° the figure such that it looks exactly the same as the original figure.
When we rotate the isosceles triangle up to 360° , only 1 time it looks exactly same as in the beginning because at each rotation the order of angles changes.
Therefore, An isosceles triangle has an order 1 rotational symmetry because it does not have all congruent angles.
X^2 + 6^2 = {sqrt (117)}^2
x^2 + 36 = 117
Solve for x.
x^2 = 81
x = 9
