Mathematics

Part A : a) -8 b) 12

Part B : a) 0.5 b) -1

Step-by-step explanation:

For Part A:

Let the algebraic expression be $p_{1} = 4x$

so,

put $x = -2\\$ we get

$p_{1} = 4\times-2$

$p_{1} = -8$

put $x = 3\\$ we get

$p_{1} = 4\times 3$

$p_{1} = 12$

For Part B:

Let the algebraic expression be $p_{2} = 3x +2$

so,

put $x = -0.5\\$ we get

$p_{2} = 3\times-0.5 + 2$

$p_{2} = -1.5 + 2$

$p_{2} = 0.5$

put $x = -1\\$ we get

$p_{2} = 3\times-1 +2$

$p_{2} = -3 +2$

$p_{2} = -1$
