2 yards = 72 inches
3 ft = 36 inches
72 - 36 = 36
She still needs 36 inches of fabric.

Answer: a = 15</h3>
Explanation:
The jump from 13 to 39 is "times 3" when comparing the diagonal segments. So the jump from 5 to 'a' must also be "times 3" to keep the sides in the same proportion. Therefore, a = 3*5 = 15.
Or we could solve it like so
13/39 = 5/a
13a = 39*5 ... cross multiplying
13a = 195
a = 195/13 .... dividing both sides by 13
a = 15
The straight lines are asking to find the modulus or the size of the complex number.
For a complex number z = x + iy, [z] = √(x^2 +y^2)
Where x = Real Number, y = Imaginary number.
For 3 +i, x = 3, y = 1 (Note y is what number that is attached to i)
[3 + i] = √(3^2 +1^2) = √10 = 3.162
1) consistent system. at least one solution.
2) inconsistent system. no solutions (the lines are parallel)
3) dependent system. equations have same slope and y-intercept(same line)independent system.
4) equations have different slopes(2 intersecting lines)
im not sure if thats what you were looking for
