If 18,a, b,-3 are in AP, then a+b is equal to

a + b = 15

Step-by-step explanation:

The common difference d between consecutive terms is

d = a₂ - a₁ = a - 18

d = a₄ - a₃ = - 3 - b

Thus

a - 18 = - 3 - b ( add b to both sides )

a + b - 18 = - 3 ( add 18 to both sides )

a + b = 15

the answer is 0.5 mpm

step-by-step explanation:

the line goes half way through the square each time (which is 0.5 or half of course) so that would mean its 0.5 mpm.

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p
