You should do distributive property.
Answer:
Step-by-step explanation:
(5y+4+3x)(5y+4-3x) = (5y+4)² - (3x)²......(from the difference of 2 squares )
by identity : (a+b)(a-b) = a² - b²
in this exercice ; a = 5y+4 and b = 3x
If the top is $48 and it is 60% off you will multiply the cost by the decimal form of the sale percentage: 48*0.60= $28.80. This is the amount she will save and I think is the answer you are looking for.
If there is a follow up question asking for the final cost of the top you would find that by subtracting the amount saved from the original cost: 48.00-28.80=$19.20.
Answer:
aⁿ=4(−1)ⁿ⁻¹/3ⁿ
Step-by-step explanation:
use the formula an=a1rⁿ⁻¹
aⁿ=4(−1)ⁿ⁻¹/3ⁿ
Ok! The first thing u have to do is multiply 2 times 88 which its 178 then u multiply 2 times 8 which it equals 16. Then u add 178+16 and it equals 194.
