1+(put the little sign)6
that should be the answer, good luck.
Answer:
Step-by-step explanation:
Move all terms to one side
4x^2 + 4x + 5 = 0
Plug into quadratic formula
x = (-4 <u>+</u> ) / 2(4)
= (-4 <u>+</u> )/8
At this point, there are no real answers. The roots to this equation are complex.
x = (-4 <u>+</u> 8i)/8
= (-1 <u>+</u> 2i)/2
Answer:
15
Step-by-step explanation:
Using the formular, Sn = n/2(2a + (n - 1)d)
where, n = 6: Sn = 6/2( -20 + 5(3)) = 3(15 - 20)
∴ Sn = 15
Answer:
12
Step-by-step explanation:
Because I think it is
Part A :
So the two sides are equivalent,
Solve for x and get 3.
~~
Answer : x = 3
~~
Part B :
To find JM, simply substitute x for 3 and solve,
~^
Answer : JM = 9
