You are adding 2 each time.
You are trying to find the 30th term, in which 4 are shown.
Subtract 4 from 30
30 - 4 = 26
Multiply 26 with 2
26 x 2 = 52
Add 52 to the last number given (0)
0 + 52 = 52
52 is your answer
hope this helps
Answer:
40 degrees
Step-by-step explanation:
Because Angle RST is bisected by ray SU it is then split into two even angles and the resulting two angles will be 40 degrees apiece.
132 degrees
37 degrees
169 degrees
180 degrees
Answer:
B
Step-by-step explanation:
Given a quadratic equation in standard form
ax² + bx + c = 0 ( a ≠ 0 )
Then the discriminant is
Δ = b² - 4ac
• If b² - 4ac > 0 then 2 real irrational roots
• If b² - 4ac > 0 and a perfect square then 2 real rational roots
• If b² - 4ac = 0 then 1 real double root
• If b² - 4ac < 0 then 2 complex roots
Given
x² + 3x - 7 = 0 ← in standard form
with a = 1, b = 3, c = - 7 , then
b² - 4ac
= 3² - (4 × 1 × - 7) = 9 + 28 = 37
Since b² - 4ac > 0 then 2 real irrational roots
