Answer:
4x(2x + 3)
Step-by-step explanation:
Cos is the adjacent (side next to the angle in question) divided by the hypotenuse (sloped side)
for angle K, this is therefore 7/25
Answer:
B
Step-by-step explanation:
You know two lines y=ax+b and y=mx+n that are perpendicular, so we have the product a*m=-1
+ This line is perpendicular to y=13x-5, so it has equation: y=-1/13x+b
+ And it passes through the point (3;1), so we have x=3, y=1. So 1=-1/13 *3+b
and b= 1+3/13= 16/13
And we have y=-1/13x+16/13
