Answer:
2/4
Step-by-step explanation:
when you subtract fractions with the same denominator, only the numerator changes
we know 3 - 2 = 1
so if we put those over 4, its the same as
3/4 - 2/4 = 1/4

Given:
2x² + 8x - 12 = 0
Solution:
The first term 2x² can't be changed to a complete square form. If we want to change it to the complete square form, we need to change 2x² to 4x². So, multiply both sides of the equation by 2
2x² + 8x - 12 = 0
------------------------- multiplied by 2
4x² + 16x - 24 = 0
then change it to complete quadratic form by adding 16 to both sides
4x² + 16x - 24 = 0
4x² + 16x + 16 - 24 = 16
4x² + 16x + 16 = 16 + 24
4x² + 16x + 16 = 40
(2x + 4)(2x + 4) = 40
(2x + 4)² = 40
This is the complete quadratic form of the equation.
Because there is no option of the solution, we can modify the equation by multiplying the two sides by a square number. I multiply the equation by 4.
(2x + 4)² = 40
4 (2x + 4)² = 4 × 40
4 (2x + 4)² = 160
4 (2x + 4)(2x + 4) = 160
2(2x + 4) 2(2x + 4) = 160
(4x + 8)(4x + 8) = 160
(4x + 8)² = 160
The answer is option b

Answer:
Scalene triangle
Step-by-step explanation:
Coordinates of the vertices of the triangle are,
W(-7, 1), X(0, -4) and Y(2, 3)
We will use the formula to get the distance between two points.
d =
WX =
=
WY =
=
XY =
=
=
Since, measures of all three sides of the triangle are not equal, given triangle will be a scalene triangle.
D. they are corresponding angles and their measures add to 180°
