1.1 The chalkboard is on the Western side of the classroom. it has a length of 4m and a breadth of Im. The chalkboard does not need to be painted.
Western wall
3m
8m
1.1.1 Calculate the perimeter (in m) of the Western wall.
Hint: Perimeter of rectangle = 2(length) + 2(breadth)
(2)
1.1.2 Calculate the area (in m?) of the Western wall to be painted.
Hint: Area of rectangle = length x breadth

x/3-10=8

x/3=18

x=48

oof

step-by-step explanation:

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8
