Given: △KLM, LM=20 3
egoroff_w [7]

Split the triangle into a 30-60-90 triangle. Since you have LM from that triangle, you can figure out the other sides. Then, using the leg from that triangle, the one next to it is a 45-45-90 triangle, meaning it's isosceles.

KM = 30 + 10√3

KL = 10√6

(sorry i'm not too sure if my "reasons" for statement/reason is correct)

(9h+3)(−h−1) porfavor ayudenme con esta pregunta.
BartSMP [9]

Answer:

-9h² - 12h - 3

Step-by-step explanation:

Follow the FOIL method:

FOIL = First, Outside, Inside, Last

Multiply the terms together:

First: 9h * -h = -9h²

Outside: 9h * -1 = -9h

Inside: 3 * -h = -3h

Last: 3 * -1 = -3

Combine like terms: 9h² + (-9h - 3h) - 3

9h² - 12h - 3

-9h² - 12h - 3 is your answer.

What is 9x + 18 = 6y - 3x for y ​
Nana76 [90]

Answer: 2x+3

Step-by-step explanation:

9x+18=6y-3x Our goal is to isolate y.

Let's add 3x to both sides of the equation to cancel out that -3x on the right side.

12x+18=6y Because all of these integers are divisible by the gcf of 6, we can divide both sides of the equation by 6.

2x+3=y

Hope this helps!
