Answer:

w < -5

Step-by-step explanation:

8w + 9 < −31

Step 1: Subtract 9 from both sides.

8w + 9 − 9 < −31 − 9  

8w < −40

Step 2: Divide both sides by 8.

8w/8 < -40/8

w< -5

QUESTION 5
Anna [14]

Answer:

P\cup Q=\{1,\ 2,\ 3,\ 4,\ 5,\ 7,\ 8,\ 9, \ 10,\ 11\}

Step-by-step explanation:

The union of two sets P and Q, denoted as P\cup Q, is the set of all elements that are in the set P or in the set Q or in both sets P and Q.

Given:

P = {7, 8, 9, 10, 11}

Q = {1, 2, 3, 4, 5}

Then

P\cup Q=\{1,\ 2,\ 3,\ 4,\ 5,\ 7,\ 8,\ 9, \ 10,\ 11\}

When writing the union set, simply write all elements from both sets in on set.

Assoli18 [71]

Answer:

36 units

Step-by-step explanation:

to do this you must first find the lengths of all the sides with pythagorean theorem

for a to b you use

3^2 + 4^2 = c^2

9 + 16 = c^2

25 = c^2

c = 5

5 is one of the lengths

b to c uses the same equation

so

5 is another one of the lengths

for d to c your equation is

5^2 + 12^2 = c^2

25 + 144 = c^2

169 = c^2

13 is another of the lengths

d to a has the same length as c to d so there is another 13 unit length

so

5 + 5 + 13 + 13 is your equation to find the perimeter

5 + 5 + 13 + 13 = 36

that is your answer
