Question

T = 3x + 4y
x = 5
y=-3
(a) Work out the value of T.
(b) Expand 3g(8 + 3)

Answer 1

A.) let's solve for T :

• T = 3x + 4y

plugging in the values of x and y,

• T = (3 × 5) + (4 × -3)

• T = 15 - 12

• T = 3

value of T = 3

B.) Expansion of 3g(8 + 3)

• 3g (8 + 3)

• 3g (11)

• 33g

that's all...
