Answer:
x(7x+34)
=(x)(7x+34)
=(x)(7x)+(x)(34)
=7x2+34x
Step-by-step explanation:
Answer:
5x-6y-12=0
Step-by-step explanation:
...make y the subject y=-6/5x +2
...use the coefficient of x as the gradient,m=-6/5
...for a perpendicular line,find the negative reciprocal of the gradient,5/6
...sub into the eqn y= -1/m(x-a)+b
There are 360 degrees so divide 360 by 20 and get 18 degrees
