Answer:
a = 21
Step-by-step explanation:
If x = h is a zero of a polynomial then f(h) = 0, thus
p(- 
) = 27( - )³ - a(- ) - (- ) + 3 = 0, that is
27 (- 
) - 
a + + 3 = 0
- 1 - a + 
= 0 ( multiply through by 9 to clear the fractions )
- 9 - a + 30 = 0
- a + 21 = 0 ( subtract 21 from both sides )
- a = - 21 ( multiply both sides by - 1 )
a = 21
Answer:
Right angle triangle goes to 15m, 8m, 17m
Step-by-step explanation:
Square root of 15^2 + 8^2 is 17
(The use of a^2 + b^2 = c^2 - Pythagoras's Theorem)
So, 10m ,11m ,15m isn't a right angle triangle
