Hi there! The answer is 8 + 13t

We can combine 19t and -6t. When we subtract these from each other, we get the following: 19t - 6t = 13t
(If you don't understand this, you can see it as a story -- You have 19 apples (19a) and subtract 6 apples (6a), what's left? Answer 13t)

We can't add the seperate number (8) to this 13t, so it rests "free-standing"
Hence, 8 + 13t

Type the correct answer in each box. Use numerals instead of words. Based on the Pythagorean theorem, find the missing length fo
Neporo4naja [7]

Answer: See below

Step-by-step explanation:

The Pythagorean Theorem is a²+b²=c². Since each problem gives us the length of a, b, or c, we can directly plug them into this equation and solve.

Triangle EFG

9²+b²=41²

81+b²=1681

b²=1600

b=√1600

b=40

----------------------------------------------------------------------

Triangle PQR

20²+21²=c²

400+441=c²

c²=841

c=√841

c=29

----------------------------------------------------------------------

Triangle XYZ

a²+24²=25²

a²+576=625

a²=49

a=√49

a=7
