Answer:
thank you for the points
Step-by-step explanation:
Answer:
-4 and 5
Step-by-step explanation:
4*5 = x(x-1) ; cross multiply
20 = x²-x ; distribute multiplication over subtraction
x²-x-20 =0; subtract 20 from both sides
(x+4) (x-5) = 0; factor
x+4 =0 gives x = -4
x-5 =0 gives x = 5
The tangent of an angle is the trigonometric ratio between the adjacent side and the opposite side of a right triangle containing that angle. Example: In the triangle shown, tan(A)=68 or 34 and tan(B)=86 or 43 .
Answer:x = -4
Step-by-step explanation:
-3x + 4 = -4x , 4 = -4x + 3x , 4 = -x , divided the - to both sides, x = -4
I think that the answer is letter b
