Question

Evaluate the following expressions for x = 2.

Answer 1

Answer:

$-9.2(4 - x) = -18.4$

$-36.8 + 9.2x =-18.4$

Explanation:

Given

$-9.2(4 - x)$

$-36.8 + 9.2x$

Required

Evaluate when $x =2$

$-9.2(4 - x)$

Substitute 2 for x

$-9.2(4 - x) = -9.2(4 - 2)$

Evaluate the expression in bracket

$-9.2(4 - x) = -9.2(2)$

Remove bracket

$-9.2(4 - x) = -9.2*2$

$-9.2(4 - x) = -18.4$

$-36.8 + 9.2x$

Substitute 2 for x

$-36.8 + 9.2x = -36.8 + 9.2 * 2$

$-36.8 + 9.2x = -36.8 + 18.4$

$-36.8 + 9.2x =-18.4$

Answer 2
