Answer:
Step-by-step explanation:
3x2 - y2 = 9.........(1)
x2 + 2y2 = 38......(2)
Let x^2 = a and y^2 = b
:- the two equations becomes
3a - b = 9..........(3)
a + 2b = 38.......(4)
Multiplying (4) by 3
3a + 6b = 114........(5)
Substracting (3) from (5)
3a - 3a + 6b - (-b) = 114 - 9
6b +b = 105
7b = 105
b = 105/7
b = 15
And 3a - b = 9 putting b = 15
3a - 15 = 9
3a = 15+9
3a = 24
a = 24/3
a = 8
And
x^2 = a
x^2 = 8
x = √8
x = √(4×2)
x = 2√2
Also y^2 = b
y^2 = 15
y = √15
Solution - 49 jellybeans divided by 7 for the ration purposes = 7 so 1/7 the ratio is 7
Therefore Kim having 4/7 is 4 X 7
Answer - 28
The perimeter of one of those six squares formed is 24 inches.
The rectangle measures 12 inches by 18 inches.
The rectangle is cut into six identical square by making three cut.
Therefore, let's find the area of the rectangle:
<h3>Area of a rectangle:</h3>
- a = 12 × 18 = 216 inches²
<h3>Area of a square:</h3>
The square formed are 6 in numbers. Therefore,
6l² = 216
l² = 216 / 6
l = √36
l = 6 inches
The length of each square formed is 6 inches.
Therefore, the perimeter of each square formed is as follows;
