Explain how you would solve this question Solve for x: 4 − (x + 2) < −3(x + 4)

x < −7

x > −7

x < −9

x > −9

x < -7

Step-by-step explanation:

4 − (x + 2) < −3(x + 4)

4 -x -2) < -3x - 12

2- x < -3x - 12

2 + 12 < -3x + x

14 < -2x

÷ -2 when we divide with a negative number we flip the inequality

-7 > x

B

Step-by-step explanation:

Δ CBA and Δ CDE are similar triangles, then the ratios of corresponding sides are equal, that is

= , substitute values

= = 3 ( multiply both sides by x )

32 - x = 3x ( add x to both sides )

32 = 4x ( divide both sides by 4 )

8 = x

Then

BC = 32 - x = 32 - 8 = 24 → B
