When we solve this, it's going to be the same process as solving 5(x-6) = 20, except at each step we need to think about whether we change the inequality round or keep it the same. There are two ways of d...

√40 + √90

= (√10 x √4 ) + (√10 x √9 )

= 2√10 + 3√10=5√10

5(x + 3) < 60Multiple the number outside of the bracket with the contents of the bracket:5x + 15 <60 Next, bring all the numbers to one side 5x <60-15Now simplify 5x < 45Simply further x < ...

A vector is something that has both magnitude and direction. An example of a vector is velocity because it has magnitude and direction. However, speed is not a vector. Th...

x=300 because when you draw a y=cos x graph the cos 60 is on the decreasing part of the curve just before 90 degrees crossing zero. Then at 270 its increasing again and its 30 degrees more.
