a) answer
to prove the given triangles ABC and ADC are congruent we should use S.S.S axiom because all the sides of given triangles are equal.
b) answer
we cant use S.A.S axiom where it look like that given triangles BAC and DAC angle are equal because same length
of sides cant decides the angle.
Answer:
<em>2x^2 - 7x - 4</em>
Step-by-step explanation:
Given the expression f(x) = (2x+1)(x – 4)
To write it in standard form, we need to factorize it
(2x+1)(x – 4)
= 2x(x) - 2x(4) + x - 4
= 2x^2 - 8x + x - 4
= 2x^2 - 7x - 4
<em>hence the expression in standard form is 2x^2 - 7x - 4</em>
Answer:
M=55
Step-by-step explanation:
Since the lines are parralel then the angles would have to equal 180 degrees. You would sybtract 180-125 and get 55
