Answer:
w= -1
Step-by-step explanation:
Use PEMDAS to solve.
9(1 + w) - 5w = 5
distribute 9 to everything inside the parentheses.
9 x 1 = 9
9 x w = 9w
rewrite equation
9 + 9w - 5w = 5
combine like terms
9w - 5w = 4w
rewrite equation
9 + 4w = 5
subtract 9 from both sides
9 - 9 = 0
5 - 9 = -4
rewrite equation
4w = -4
divide by 4 on both sides to get w by itself.
4w / 4 = w
-4 / 4 = -1

Answer:y = 11
Step-by-step explanation:
Infinitely many, because if you simplified the right side, it would equal the left side.
Let the other 2 unknown sides be y n z
look at the two smaller triangles inside
y^2 = 12^2 + x^2 and
z^2 = 21^2 + x^2
from the biggest triangle
(12+21)^2 = y^2 + z^2
substituting
(12+21)^2 = (12^2 + x^2) + (21^2 + x^2)
33^2 = 12^2 + 21^2 + 2x^2
2x^2 = (33^2 - 12^2 - 21^2)/2 = 504
x^2 = 252
x = 15.9
