A common way to simplify this problem would be to use an area model, or the distributive property. Using the distributive property does not require any drawing, so here goes.
(x-3)(x²+7x-8) Distribute by multiplying each of the terms in the first set of parentheses by every term in the second set of parentheses.
x³+7x³-8x-3x²-21x+24 Then combine alike terms.
8x³-3x²-29x+24 Is your final answer.
£45 600 is more than £43 000 and less than £150 000. According to the third • point, the tax will be 40%.
Also, according to the first • point, the first £11 000 will not be taxed. So, only £34 600 will actually be taxed.
To finally get the answer, Multiply £ 34 600 by the rate of 40%, and the result is £ 13 840.
Writing the word problem as an equation you get:
x - 18 ≥ -12
Now to solve for x:
Add 18 to both sides of the inequality:
x ≥ -12 + 18
Simplify:
x ≥ 6
