Answer:
Step-by-step explanation:
Just substitute in 7 for the n.

Answer:
B
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
y + 10 + 2y + 50 = 180 , that is
3y + 60 = 180 ( subtract 60 from both sides )
3y = 120 ( divide both sides by 3 )
y = 40 → B
Answer:
56.
Step-by-step explanation:
= -(8-12)+60+(-4)*2
= -(-4)+60+(-4)*2
= 4+60+(-4)*2
= 4+60+-4*2
= 4+60-4*2
= 4+60-8
= 64-8
= 56
quadratic formula:
x = <u>-b ± √(b² - 4ac)</u>
2a
7x² - x = 7
subtract 7 from both sides:
7x² - x - 7 = 0
plug values into the quadratic formula:
x = <u>-(-1) ± √((-1)²- 4(7)(-7))</u>
2(7)
simplify:
x = <u>1 ± √(197)</u>
14
