Jamie ordered 24 combo meals for $5 each for a party. The service charge for home delivery for the whole purchase was $6.

My name is Ann [436]

24 * 5 = 120
120 + 6 = 126 - total cost - meals and service

6/126 *100% = 4,76%

service charge was 4,76% of total costs.

What are the answers for question 1 and 2??

xeze [42]

Answer:

1) Answer: 3) $~~x = -3 \pm \sqrt{7}$

2) Answer: 3) 2 and -6

Step-by-step explanation:

$(x + 3)^2 = 7$

$x + 3 = \pm \sqrt{7}$

$x = -3 \pm \sqrt{7}$

Answer: $3)~~x = -3 \pm \sqrt{7}$

$2(x + 2)^2 - 4 = 28$

$2(x + 2)^2 = 32$

$(x + 2)^2 = 16$

$x + 2 = \pm \sqrt{16}$

$x + 2 = \pm 4$

$x + 2 = 4$ or $x + 2 = -4$

$x = 2$ or $x = -6$

Answer: x = 2 or x = -6
