Answer:
Step-by-step explanation:
your basically multiplying everything in the first parenthesis by everything in the second parenthesis
(x + 4y + z)(x - 7y) =
x(x - 7y) + 4y(x - 7y) + z(x - 7y) =....keep in mind, 4yx is the same as 4xy
x^2 - 7xy + 4xy - 28y^2 + zx - 7zy....combine like terms
x^2 - 3xy - 28y^2 + zx - 7zy <---- your answer
this is the distributive property
-160
Since -(20x8) the answer would be -160
Given hyp=17 and α=29°,
X = 8.24176
base = 14.86854
