Answer:
4x²+x+5.
Step-by-step explanation:
5x²+4x+1-(X²+3x-4).
5x²+4x+1-x²-3x+4.
5x²-x²+4x-3x+1+4.
4x²+x+5.
Answer:
20, 35, 50
Step-by-step explanation:
Answer:
x = 15
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
=
, substitute values
=
( cross- multiply )
56(3x - 5) = 32(5x - 5) ← distribute and simplify both sides
168x - 280 = 160x - 160 ( subtract 160x from both sides )
8x - 280 = - 160 ( add 280 to both sides )
8x = 120 ( divide both sides by 8 )
x = 15
