The expression multiplied by 1 stays the same so you use the communitive property to reorder the terms so now u have 14x
Answer:
D = 120, there are 2 real roots for F(x)
Step-by-step explanatU
using the
formula D = b^2 - 4ac for discriminant
D = 8^2 - 4*(-7)*2
D = 64 + 56 = 120
9514 1404 393

Answer:
- 3.5229
Step-by-step explanation:
Using the rules of logarithms
logx + logy = log(xy)
= n
Given
3 ≈ 0.4771, then
0.0003
=
(3 ×
)
=
3 +

≈ 0.4771 - 4
≈ - 3.5229 ( to 4 dec. places )
