Answer and working out please!
frosja888 [35]

Answer:

17.0710678119 and 2.92893218813

Step-by-step explanation:

Theoretically, the wire should come out to be x+y=80,

and the sum of the areas of the squares should be (x/4)^2+(y/4)^2=300.

x/4 and y/4 being the length of one side of the square, we would then square that to find the area. The total wire is all x+y=80. X being one part and Y being the other.

Theoretically, using systems. i found the answers: 68.2842712474619,11.715728752538098

Again, these numbers are very large, and I they actually do both add up to each amount basically perfectly. If your teacher is asking for a rounded answer, that would've been helpful to know. But again, theoretically, those are the answers.

NEED HELP ASAP WILL MARK BRAINLIEST IF RIGHT!!!​
Zarrin [17]

Answer: Area = x² + 6x + 8

Step-by-step explanation:

Area = length x width

Area = (x+2)(x+4)

Area = (x)(x) + (x)(4) + (2)(x) + (2)(4)

Area = x² + 4x + 2x + 8

Area = x² + 6x + 8

She had $3000. She spend 40% of the money in smart TV and 15% of the remainder on Game Set. (a) What % of the money had she left
Dovator [93]

Answer: She had left 54% of the money which is $1620.

Step-by-step explanation:

40% of $3000 = $1200

15% of $1200 = $180

$3000 - ($1200 + $180)

$3000 - $1380 = $1620

$1620 is the money she had left.

$1620 is 54% of $3000

She had 54% left of the money.

Hope that helped~!
