I need help this question?
Masja [62]

Answer:

Correct answer:  F. graph F or x ∈  |-5 ; 5| (including endpoints)

Step-by-step explanation:

Let us first define the absolute value:

| x |  = 1. { x with condition x ≥ 0 }

    or 2. { - x with condition x < 0 }

This is a linear inequality

1.  x ≤ 5  ∧  x ≥ 0   ⇒   0 ≤ x ≤ 5  or interval x ∈  |0 ; 5| (including endpoints)

2. - x ≤ 5  when we multiply both sides of the equation by -1 we get:

x ≥ -5 ∧ x < 0  ⇒  -5  ≤ x < 0 or interval x ∈  |-5 ; 0) (including -5)

The solution to this linear inequality is the union of these two intervals:

x ∈  |-5 ; 0) ∪ |0 ; 5|  ⇒ x ∈ |-5 ; 5| (including endpoints)

x ∈ |-5 ; 5| (including endpoints)

God is with you!!!

Answer:

Area of regular hexagon\approx 41.57 \:  {cm}^{2}

Step-by-step explanation:

Area of regular hexagon

= 6 \times area \: of \: one \: triangle \\  \\  = 6 \times  \frac{1}{2}  \times 4 \times 2 \sqrt{3}  \\  \\  = 24 \sqrt{3}  \\  \\  = 41.5692194  \: {cm}^{2}  \\  \\   \approx 41.57 \:  {cm}^{2}
