Answer:
You divide the numerator by the denominator (top number by bottom number)
Answer:
D. x = -5/2, x = -1/2
Step-by-step explanation:
2x² + 7x + 5 = 0
(2x + 5)(x + 1) = 0
2x + 5 = 0 or x + 1 = 0
2x = -5 or x = -1
x = -5/2 or x = -1/2
Answer:
A
Step-by-step explanation:
permutation are variations of a problem, but they are collecting movies and selecting 4 out of the 20 so it is combination
<h3>
Answer: x = 29</h3>
=====================================================
Work Shown:
Focus on triangle DEC. We have angle C is 48 and D is 74. Let's find angle E.
D+E+C = 180
74+E+48 = 180
E+122 = 180
E = 180-122
E = 58
----------
In the sequences ABC and DEC, we have B and E as the second letters. The order is important because the angles must align properly (so we know how they pair up). Therefore, angle B = angle E because triangle ABC = triangle DEC.
Furthermore,
angle B = angle E
2x = 58
x = 58/2
x = 29
Answer:
5, 6, 7, 8, 9, 10, 11 and 12 are the natural numbers between 5 and 12 including them, therefore Jane wrote 8 numbers. natural numbers start at positive 1 and go up by whole numbers infinitely, hope this helps
