To have 2 real number solutions the discriminant b^2 - 4ac must be greater than zero.
so the condition for 2 real roots in this equation is:-
b^2 - 4*1*5 > 0
b^2 > 20
b > sqrt 20 ( positive root) Answer
-(28-4x)=92
-24+4x=92
4x=92+24
4x=116
x=29
X=29
Answer:
x-1= -18
x = -18 +1
x = -17
2x - 4 = - 38
2x = -38 + 4
2x = -34
x = -34/2
x = -17

Answer:
They have all together 1,208$
Step-by-step explanation:
Do subtraction first, 128- 8= 120 so Abdul as 120$
Deon is multiplication, 8x120=960$
Rita has 128$
Answer:
40ft
Step-by-step explanation:
The shape of the garden (square) tells you that both the length and the width of the garden are the same measure.
If the area is 100sqft, you can determine that side * side = 100. To find this answer, you can take the square root of 100. side=10, because 10 * 10= 100 (the area).
Now, we know that each side measures 10 feet. Try drawing and labeling a picture to help you visualize the garden. Next, label each side of the square garden 10ft. To find the feet of fencing is needed to enclose the garden,
We need to find the perimeter, so we can calculate
10ft * 4 sides = 40 feet of fencing.
