Answer:
7 + 4
Step-by-step explanation:
note that × = a
Given
(2 + )² = (2 + )(2 + )
Each term in the second factor is multiplied by each term in the first factor, that is
2(2 + ) + (2 + ) ← distribute both parenthesis
= 4 + 2 + 2 + 3 ← collect like terms
= 7 + 4
Answer:
$43.20
Step-by-step explanation:
The price with tax is 100% + 8% = 1.08 times the price before tax. The discount multplies that price by 100% -20% = 0.80. The discount multiplier is the same whether the discount is applied before or after the tax.
The combined effect of the two multipliers is ...
... 1.08 × 0.80 = 0.864
so the discounted price with tax added is 0.864 × $50 = $43.20
_____
Perhaps you're supposed to figure the tax (8% of $50 = $4), add the tax ($50 +4 = $54), then subtract the discount (20% of $54 = $10.80) to get
$54.00 -10.80 = $43.20
