If the bottom side is 20 cm, then each line BE and CE would each be 10 cm.
Now, just focus on the top left triangle. You have one side with 20 cm, and the other side with 10 cm. You are left with the hypotenuse, which you need to figure out the value of.
Since this is a right triangle, you can use the Pythagorean theorem -> a^2 + b^2 = c^2 where c is the hypotenuse.
20^2 + 10^2 = c^2
400 + 100 = c^2
500 = c^2
22.36 = c
Answer:
24
Step-by-step explanation:
To figure out what the value of y is, we must isolate the variable. To do this, we need to use the division property of equality which says that when you divide on one side of the equal sign, you must also divide on the other side.
8y/8 = y
12/8 = 1.5
This tells us the value of y, so next we have to apply this into the problem
8(1.5) = 12
12 + 12 = 24
24 is your answer
Answer (first one):

Step-by-step explanation:
think of f(x) as y.

Now find the parts on the x axis that correspond with parts on the y value that are greater than -2.

This would be all of the numbers between -2 and 8 (inclusive).
The reason it is inclusive is because the arrow ends are shaded in.
Answer: +80°C or -20°C
Step-by-step explanation:
This is the answer because if you add 80 then it will equal 100°C and freeze and if 20°C is taken away it will equal 0°C and freeze.
