Answer:

P=8x²+12y

Step-by-step explanation:

P=2L+2W; L=4x²-x+2y; W=x+4y; P=2(4x²-x+2y)+2(x+4y);

P=8x²-2x+2x+4y+8y; P=8x²+12y

Answer:

  • P = 8x² + 12y units

Step-by-step explanation:

<u>Given sides of rectangle:</u>

  • x + 4y
  • 4x² - x + 2y

<u>Its perimeter is:</u>

  • P = 2(l + w)
  • P = 2(x + 4y + 4x² - x + 2y)
  • P = 2(4x² + 6y)
  • P = 8x² + 12y

Will give brainlist if correct. Solve the system. Nearest tenth accepted.
Semmy [17]

Answer:

The variable y should equal 5 2/5 or 5.4 as a decimal.

Step-by-step explanation:

The variable x equals 1 so we can replace x in the equation y = 2/5x + 5 with 1.

y = 2/5(1) + 5

This is our new equation. Any number multiplied by 1 will equal itself so in this case, 2/5 times 1 equals 2/5 or 0.4 in decimal form. Now we can add 2/5 or 0.4 to 5 and we will get 5 2/5 or 5.4. Now we will only have y =  5 2/5 or 5/4 in the equation and this is where we will stop solving for y. In conclusion, y equals 5 2/5 or 5.4. I hope this helps! If this answer is wrong, please give me some feedback on what I did wrong! Thank you!

Mathew rolls a number cube labeled with the numbers 1−6. He then flips a fair coin. What is the probability that he rolls a 4 an
KATRIN_1 [288]

Answer:

0.083

Step-by-step explanation:

Numbers of Cube = 6

Faces on coins = 2

Therefore, The total outcomes = 6 \times 2 = 12

Now the favourable outcome that he rolls a 4 & flips a head = 1

The probability that he rolls a 4 & flips a head = 1

\frac{Favourable \: Outcome}{Total \: Outcome}

=> The probability that he rolls a 4 & flips a head = \frac{1}{2}  = 0.83333/ approx. 0.83

Therefore, The probability that he rolls a 4 & flips a head = 0.083

Find the solution of this system of equations. Separate the x- and y-values with a comma.
natita [175]
X=0+y6x−5y=23
6x=23+5yx=23+5y6
now sub x=23+5y6in x=0+ywe get23+5y6=0+ymultiple both side of the equation by 6..we get23+5y=6ynow we solve for y..23=6y−5yy=23now since we find y...we can find x..by by substituting y=23 in the 1st or 2nd equation...so, using equation 1x=0+yx=0+23x=23

Hopefully this helps :)
