4.While not rounding the answer is 500°
D = -(8-5) = -3
a = 47
an = a + (n-1)d = 47 + (-3) = 47 - 3 = 44
180-104=76
76x2=152
Answer is 152
Answer:
9(4)+4
Step-by-step explanation:
Step-by-step explanation:
using
The quadratic general formula
which is
r= -b±√(b²-4ac)
---------------
2a
b= coefficient of r=3
a = coefficient of r²=2
c= constant or number without any variable=-10
r= -3±√(3²-(4×2×-10)
-----------------------
2×2
r=-3±√(9-(-80)
----------------
4
r= -3±√(9+80)
------------
4
