Please help me with 1,2,3,4,5,6,7,8,9 tell me how u get it and the answer please I really need help

Answer:

Step-by-step explanation:

Ok so for question one we use the Pythagorean theorem, which is a^2+b^2=c^2

a is the shortest leg, b is the leg that is not the hypotenuse. and c is the hypotenuse which is the opposite leg to the right angle.

Question 1: a=9,b=12,c=x

(9)^2+(12)^2=(x)^2

81+144=(x)^2

225=(x)^2

x=15

Question 2: a=10,b=24,c=x

(10)^2+(24)^2=(x)^2

100+576=(x)^2

676=(x)^2

x=26

Question 3: a=3,b=7,c=x

(3)^2+(7)^2=(x)^2

9+49=(x)^2

58=(x)^2

x=root58, or 7.615773

Question 4: a=6,b=x, c=10

(6)^2+(x)^2=(10)^2

36+(x)^2=100

Subtract 36 from both sides

(x)^2=64

x=8

Question 5: a=6,b=x, c=24

(6)^2+(x)^2=(24)^2

36+(x)^2=576

Subtract 36 from both sides

(x)^2=540

x=6root15, or 23.2379

Question 6: a=1, b=1, c=x

(1)^2+(1)^2=(x)^2

1+1=(x)^2

2=(x)^2

x=root2, or 1.414213562

Question 7: a=8, b=x, c=21

(8)^2+(x)^2=(21)^2

64+(x)^2=441

Subtract 64 from both sides

(x)^2=377

x=root377, or 19.41648784

Question 8: a=24, b=x, c=30

(24)^2+(x)^2=(30)^2

576+(x)^2=900

Subtract 576 from both sides

(x)^2=324

x=18

Question 9: a=5,b=9, c=x

(5)^2+(9)^2=(x)^2

25+81=(x)^2

106=(x)^2

x=root106, or 10.29563014

Question 9 Part B: a=3, b=5, c=y

(3)^2+(5)^2=(y)^2

9+25=(y)^2

34=(y)^2

root34, or 5.830951895=y

write 19/41 in lowest forms

evaluate 4z -5y when z=8 and y=3
