Answer:
X = - 2 or X = 2
Step-by-step explanation:
*completing the square*
X^2 - 4 = 0
X^2 = 4
X = +-√4
x = +-2
x= -2, 2
*factoring*
X^2 - 4 = 0
(x-2)(x+2) = 0
|. |
x = 2, x = -2
________________________________
(x-2)(x+2) = x(x+2) - 2(x+2) = x^2 + 2x - 2x - 4 = x^2-4

Figure ABCD is a parallelogram. Is triangle ADB congruent to triangle CBD? Show or explain your reasoning
Answer:
yes it's congruent.
Step-by-step explanation:
in a parellelogram, all sides and angles are equal.
ΔADB is congruent to ΔCBD.
The reasoning is given below.
What is a parallelogram?A parallelogram is a quadrilateral that has two pairs of parallel sides.
In a parallelogram, opposite sides and angles are equal.
The adjacent angles add up to 180 degrees.
We have,
A parallelogram ABCD.
This means,
AD is parallel to BC
AB is parallel to CD
∠A = ∠C
BD is the diagonal of the parallelogram.
Now,
ΔADB and ΔCBD
AB = CD ( given )
∠A = ∠C (given )
∠ADB = ∠CBD ( given )
∠ABD = ∠BDC ( alternate angles )
ΔADB ≈ ΔCBD
Thus,
ΔADB is congruent to ΔCBD.

Ashley is going to rent a truck for one day. There are two companies she can choose from, and they have the following prices.
Company A charges $77 and allows unlimited mileage.
Company B has an initial fee of $65 and charges an additional $0.80 for every mile driven.
For what mileages will Company A charge less than Company B?
Use m for the number of miles driven, and solve your inequality for m.
Answer:
Anything above 15 miles, so x>15
Step-by-step explanation:
When you solve this by using an equation, you would get 77=65+0.80m (0.80 m because slope is 0.80 and m is mileage you multiply by). You would subtract 64 from both sides, so 12=0.80m and then you divide 0.80 by 12 to get m by itself to get 15. 15 miles is when both companies cost the same, so anything above 15.

Answer:
2x + 200 = 6x + 120
Step-by-step explanation:
Super-Clean house cleaning company: 2x + 200
Power Bright: 6x + 120
Now, they have to be equal because we are trying to find the equation for total charges.
So, your equation would be 2x + 200 = 6x + 120.
Hope this helps!
Answer:
Step-by-step explanation:
Let the number of linear feet = x
Let the total cost = y
Condition One
y = 200 + 2x
Condition Two
y = 120 + 6x
Now you want the ys to be the same.
200 + 2x = 120 + 6x

Which statement most reasonably explains the hours when zero calls were received? Medera turned the phone off while playing in a soccer game. Medera's phone can only receive 22 calls a day. Medera only receives calls in clusters. Medera lost her phone for two hours.
Answer:
Medera turned the phone off while playing in a soccer game.
Step-by-step explanation:
From the possible scenarios provided the one that would indicate this would be when Medera turned the phone off while playing in a soccer game. This is because since her phone was off it was not getting any phone signal which means that no incoming calls would have been received during that time. When Medara lost her phone for two hours, even though she did not have it on her the phone was still on and connected to a network which means that the calls were coming in.
