3(5x+2)=8x+20

15x+6=8x+20

15x-8x=20-6

7x=14

then you divide both sides by 2

The answer is 2.

<span>3(5x + 2)=8x + 20
Use distributive property
15x + 6=8x + 20
Subtract 8x from 15x so that the variable x is only on one side.
7x + 6= 20
Subtract 6 from both sides
7x = 14
Divide 7 on both sides so that the only thing remaining on the left side is the variable x.
Final Answer: x= 2</span>

Lesson 13.3 Checkpoint
Arte-miy333 [17]

Answer:

a. LK = 4√3, JL= 4√6

b.  PQ = 10√3, RP = 5√3

Step-by-step explanation:

a. LK =4√3,

LK=KJ= 4√3

sin(45°) = opposite/hypotenuse

hypotenuse (JL)= opposite/sin 45° = 4√3/√2/2 = 8√3/√2 = 8√3√2/2 = 4√6

b.

cos 30° = adjacent/hypotenuse = QR/PQ = 15/PQ

cos 30° = 15/PQ

PQ = 15/cos 30° = 15/√3/2)= 30/√3 = 30√3/3 = 10√3

tan 30° = opposite/adjacent = RP/QR

√3/3 = RP/QR

√3/3 = RP/15

RP = √3*15/3 = 5√3
