Help ASAP!!!!<br> Please show work thank you
tatyana61 [14]

Step-by-step explanation:

1. x² = V12²+16²

= V144+256

= V400

x² = 20

2. x² = V14²-11²

= V196-121

= V75

x = V25×3

= 5V3

3. x² = V9²-7²

= V81-49

= V32

x = V16×2

= 4V2

Answer:

They are equal

Both answer is 65

Step-by-step explanation:

5x -30 = 2x +27

5x -2x = 27 +30

3x = 57

x = 57/3 = 19

5x -30 = 5(19) -30 = 65

2x +27 = 2(19) +27 = 65

Can u figure out the surface area and volume i will give brainlest
Mama L [17]

Answer:

Volume: 120

SA: 400

Step-by-step explanation:

Volume = Bh

Volume = (1/2 x b x h) h

Volume = (1/2 x 6 x 4) 10

Volume = 120

SA = 2B + Ph

SA = 2(1/2 x b x h) + (s + s + s)h

SA = 2(1/2 x 6 x 4) + (5 + 5 +6) 10

SA = (24 + 16) 10

SA = 40 x 10

SA = 400
