Answer:
c: add x to each side
Step-by-step explanation:
I am 100% sure that A equals -2.3
4x²+3x-10
= 4x² + 8x -5x - 10
= 4x (x+2) -5(x+2)
= (4x-5) (x+2)
Option C
We know that
<span>In a right triangle
if A and B are complementary angles
cos A=sin B
therefore
if cos A=5/13
then sin B=5/13
the answer is
sin B=5/13</span>
