4x-8=9x+2
4x=9x+10
-5x=10
5x=-10
x=-2
Ok so basically.... 15^2= 9^2+ x^2
15*15
225= 81+x
-81. -81
144=x^2
12=X
Im pretty sure it’s right!
I used the formula A^2+B^2=C^2
Answer:
SA = 16x^2 +30x+6
Step-by-step explanation:
The surface area is given by
SA = 2 (lw + lh + wh)
The length is 2x, the width is (x+3) and the height is (2x+1)
SA = 2 ((2x)*(x+3) + (2x)*(2x+1) + (x+3) (2x+1))
We need to distribute
SA = 2 ((2x^2+6x) + (4x^2+2x) + (2x^2 +6x+x+3))
Combine like terms
SA = 2 (2x^2+ 4x^2+2x^2+6x+2x +6x+x+3)
SA = 2 (8x^2+15x+3)
Multiply by 2
SA = 16x^2 +30x+6

Answer: Second option: 8/21
Solution:
P(1) = (Number of times we get 1) / (Total number of results)
Number of times we get 1 = 8
Total number of results = 21
P(1)=8/21
