Answer:
5.36
Step-by-step explanation:
Given that:
<BAD = <CAE, therefore, BD = EC
Let's take x to be the length of BD = EC
BD + DE + EC = BC
BC = 20,
BD = EC = x
DE ≈ 9.28
Thus,
x + 9.28 + x = 20
x + x + 9.28 = 20
2x + 9.28 = 20
Subtract 9.28 from both sides
2x + 9.28 - 9.28 = 20 - 9.28
2x = 10.72
Divided both sides by 2 to solve for x



BD ≈ 5.36
Answer:
Half of year 2043
Step-by-step explanation:
The function is: f(x) = 3.5√x + 38
where f(x) represents the percentage of U.S. women in the labor force x years after 1960.
Replacing f(x) = 70 and isolating x, we get:
70 = 3.5√x + 38
3.5√x = 70 - 38
√x = 32/3.5
x = 9.14²
x = 83.5
This means, in year 1960 + 83.5 = 2043.5, that is, at half of year 2043
You can factor x^2+6x+8 using the AC method.
Which would be: (x+2)(x+4)
