<u><em>>step 1:</em></u> <u><em>subtract 4 from both sides </em></u>

2z+4\leq -2\\\\means\\\\2z\leq -2-4\\\\then\\\\2z\leq-6

<u><em>>step 2: </em></u><u><em>divide both sides by 2</em></u>

2z\leq-6\\\\then\\\\z\leq-3

Answer:

see explanation

Step-by-step explanation:

Given

2z + 4 ≤ - 2 ( subtract 4 from both sides )

2z ≤ - 6 ( divide both sides by 2 )

z ≤ - 3

solution is x ∈ ( - ∞, - 3 ]

The parenthesis on the left means that x cannot equal - ∞

The ] on the right means that x can equal - 3

Can someone help please AC line ? Maximum 56 points.
jonny [76]

Answer:

18.1 cm

Step-by-step explanation:

Consider a segment parallel to CD and passing through B.

This segment will form a right-angle triangle with A

It's length would be equal to the length of CD (the missing length)

Height of that triangle:

11 - 4 = 7

CD² = 16² - 7²

CD² = 207

CD = sqrt(207)

AC² = AD² + CD²

AC² = 11² + 207

AC² = 328

AC = 2sqrt(82)

Which is roughly 18.1 cm
