Answer:
option 2. 0
Step-by-step explanation:
The discriminant is the part under the square root in the quadratic formula, b²-4ac. If it is more than 0, the equation has two real solutions. if it is 0, the equation has one real solutions. if it is less than 0, the equation has zero real solutions.
-b√b²-4ac /2a
This is because the square root of a negative number cannot give a real number, it will always give an imaginary number
Answer:
C
Step-by-step explanation:
As the legs and hypotenuse are same, these triangles are congruent by HL congruency
Answer: Im very sure the answer is
B
Step-by-step explanation:
Length of rectangle: 4x+3
Perimeter of rectangle: 12x+10
Solving:
4x+3 + 4x+3= 8x+6
Now we have 8x+6 but, we still need our width.
12x+10 - 8x+6 = 4x+4
So now, since we only have 4x+4 left for our width, we are going to divide that by 2 because in a rectangle, there are 2 lengths and 2 widths.
So in conclusion, the width of the rectangle is 2x+2
