You could have 2 values. The way to get them is to take the square root of 25, c is double the value you get for the first step. Why 25? Well you only have 1 other choice and that is the 1 that is in front of the x^2. That's not very helpful.
Formula
c = ± 2*sqrt(25)
Solution
c = ± 2 * sqrt(25)
c = ± 2 * 5
c = ± 10
Comment
Where does the ± come from?
You need to get + 25
If you have (x - 5)(x - 5) the last term will be -5 * - 5 = 25
Similarly you get the same result with (x + 5)(x + 5)

What will a $140,000 house cost 7 years from now if the price appreciation for homes over that period averages 7% compounded annually?
The future cost of the house will be $___
(Round to the nearest cent as needed.)
The house will cost approximately $246,359.85 seven years from now.
What is compound interest?It is the interest we earned on the interest.
The formula for the amount earned with compound interest after n years is given as:
A = P [tex](1 + r/n)^{nt}[/tex]
P = principal
R = rate
t = time in years
n = number of times compounded in a year.
We have,
In this problem,
P = $140,000
r = 0.07
n = 1 (compounded annually)
t = 7.
Plugging in these values.
A = $140,000 (1 + 0.07/1)^(1 x 7)
A = $140,000 (1.07)^7
A = $246,359.85
Therefore,
The house will cost approximately $246,359.85 seven years from now.

Answer:
first one is correct second one is 6 and third one is 2 and a half
Answer:
If one counts the blocks on the graph from the school to the stadium and back, there are three blocks one way and three blocks going back.
Altogether 6 blocks.
If Catelyn lives halfway between the park and the school, the amount of blocks is 5.
She lives halfway between. Hence, what is 5 divided by 2?
2.5 or 2 1/2 blocks.

Step-by-step explanation:
It is given that, The circumference of a circle is 198 cm and we are to find the radius of the circle.

ohn drove from Miami to Atlanta, and the trip took him a total of 10 hours.
For 6 hours John’s average speed was 73 mph. His average speed on the remainder of the
trip was 67 mph. What was his average speed on the entire trip?
a) 70.8 mph
b) 70.6 mph
c) 69.4 mph
d) 68.2 mph
Answer:
b) 70.6
Step-by-step explanation:
To calculate average you need to add up all the numbers and divide by the quantity of numbers. They are calculating with mph, with ten hours, so there will be ten numbers. First you do 73 x 6 (6 because of 6 hours of 73 mph) which is 438. Then you do 67 x 4 which is 268. you add it up, then find a total of 706. Then you divide it by ten to find the answer 70.6

Make a very crude diagram of what these points look like. You will find that
(-8,6) is above (-8,3) (-3,6) is above (-3,3)That gives you a hint about how to find the Length and width.
Givens
From (-8,-3) and (-3, 3) L = -8 - -3 = - 5
From (-8,6) and (-8,3) w = 6 - 3 = 3
Solution
The length cannot be minus 5. The way to get around that is to call it and absolute value of (-5) which is 5
So the area = L*W
area = 5 *3
area = 15
Answer
Area = 15

If We replace x by -3 and y by 2 we get :
[tex]9\left( -3\right)^{2} \left( 2\right)^{-2}[/tex]
Or we have :
[tex]\left( -3\right)^{2} =9\ \text{and} \ \left( 2\right)^{-2} =\frac{1}{2^{2}} =\frac{1}{4}[/tex]
then
[tex]9\left( -3\right)^{2} \left( 2\right)^{-2}=9\times9\times\frac{1}{4} = \frac{81}{4}[/tex]
on the other hand :
[tex]\frac{81}{4} =\frac{80+1}{4} =\frac{80}{4} +\frac{1}{4} =20+\frac{1}{4}=20\frac{1}{4}[/tex]
What is the radius of a circle that has a circumference of 3.14 meters?
circumference= 3.14m
to find:the radius of the circle
solution:Circumference of a circle = 2πr
Given, circumference = 3.14 meters
Therefore:
2πr = Circumference of a circle
2πr = 3.14
2 × 3.14r = 3.14,[Putting the value of pi (π) = 3.14]
6.28r = 3.14
r = 3.14/6.28
r = 0.5
I need help on number 9
Answer:
3. -1/3 ± 2i√5 / 3
Step-by-step explanation:
3x^2 + 2x = -7
Divide through by 3:
x^2 + 2/3 x = -7/3
Completing the square:
x^2 + 2/3 x + (1/3)^2 = -7/3 + (1/3)^2
(x + 1/3)^2 = -7/3 + 1/9
(x + 1/3)^2 = -20/9
x + 1/3 = ±√(-20) / 3
x + 1/3 = ± 2√-5/3
x = -1/3 ± 2i√5 / 3
