Answer:
B: BC ≅EC
Step-by-step explanation:
You know that the two angles starting in C are congruent (they're opposite by vertex C).
Given that the B angle and the E angle are congruent, in order for the two triangles to be congruent by A(ngle)S(ide)A(ngle) you want the side inbetween to be congruent. That is BC and EC. Option B
Which is not labeled correctly
(8x^2-9y^2-4x)+(x^2-3y^2-7x)
First, get rid of the parentheses and combine like terms
(8x^2+x^2)(-9y^2-3y^2)(-4x-7x)
9x^2-12y^2-11x is your answer
Answer:
925 marks.
Step-by-step explanation:
AS Biraj had 20 less marks then the 40% pass mark must be 350+20 = 370.
370 is equivalent to 40%
So 100% = 100*370 / 40
= 925 marks.
