Answer:
13: 59
14: 118
Step-by-step explanation:
This is your information...
Length: 2x + 7
Width: 3x + 8y
Perimeter: 2(l + w) ...or... 2l + 2w
Now let's substitute...
2(l + w)
l = 2x + 7
w = 3x + 8y
2(2x+7+3x+8y)
Now combine the like terms:
2(5x+7+8y)
Now distribute the number 2:
10x+14+16y
That is the perimeter
I HOPE THIS HELPED!!!! :D ;D
Answer:
16x^2
Step-by-step explanation:
To find the area of a square, we use the formula
A = s^2 where s is the side length
A = (4x)^2
A = 16x^2
<span>The Total number of Marbles contained in the Box is as follows:
5 (Red) + 8 (green) + 4 (blue) + 3(yellow) = 20 Marbles
The Probability of selecting the first Marble (Red) is 5/20
Then 19 Marbles will be left.
The probability of selecting the second Marble green is 8/19
Since the first marble was not replaced then the probability of selecting a red marble and then a green marble is = 5/20 * 8/19 = 2/19.</span>
