Answer:The quadratic formula helps us solve any quadratic equation. First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√(b²-4ac))/(2a) .The four methods of solving a quadratic equation are factoring, using the square roots, completing the square and the quadratic formula.
Step-by-step explanation: 6x² + 11x - 35 = 0.
2x² - 4x - 2 = 0.
-4x² - 7x +12 = 0.
20x² -15x - 10 = 0.
x² -x - 3 = 0.
5x² - 2x - 9 = 0.
3x² + 4x + 2 = 0.
-x² +6x + 18 = 0.

a.4:55 p.m. b.5:00 p.m. c.5:05 p.m. d.5:10 p.m.
Answer:
5: 05
Step-by-step explanation:
35 + 15 + 5 = 55
60 - 55 = 05
5:05
Answer: 5:05 pm. (C)
Step-by-step explanation:
For this, you have to add up the times. 35+15+5. That is 55 minutes. If it would take 55 minutes, you will want to subtract 55minutes from the time you want it to be done. This will give us 5:05pm.

Answer:
k = 2
Step-by-step explanation:
9 = k(6) - 3
12 = 6k
k = 2
Answer:
k = 2
Step-by-step explanation:
We know that in the coordinates (6, 9) 6 is X and 9 is Y. So, we can just plug that into the equation in the problem to get 9 = 6k - 3. Then, after solving, we get the answer as k = 2.

What type of angle relationship is shown?
Answer:
straight angle
Step-by-step explanation:
9x_15+2x_3=180
11x_18=180
11x=180+18
11x=198
x=198÷11
x=18
Answer:
The angles are a linear pair.
x = 18
Step-by-step explanation:
The angles are a linear pair, meaning the angles add up to 180 degrees.
(9x - 15) + (2x - 3) = 180
11x - 18 = 180
11x = 198
x = 18
Sam purchased a laptop at $800 each year the laptop will lose 12% of its value each year what would it be the approximate value of Sam's laptop after 7 years
Answer:
$326.94
Step-by-step explanation:
For this equation you are going to do a exponential function, since we are working with percents. To do this you will make the equation
(starting price)x(1-percent)^(t) t=years
which will create the equation
800(0.88)^t
You will then plug in t=7
800(0.88)^7 =
800(0.409) =
326.94 (you will cut it off at the hundredth position because it is working with money)

Is Figure A congruent to Figure B? Explain.
No, because the orientation of Figure B is not the same as Figure A.
Yes, because Figure B can be obtained from Figure A by a series of translations.
Yes, because Figure B can be obtained from Figure A by a rotation and a translation.
No, because there is no sequence of translations, rotations, and reflections by which Figure B can be obtained from Figure A.

Answer:
6,666.67cube units
Step-by-step explanation:
Volume of the square based pyramid = BH/3
B is the base area
H is the height of the pyramid
Base area = Length * length
B = 25 * 25
B = 625 square units
Height = 32units
Volume = 625*32/3
Volume = 6,666.67cube units

Explain how you
use a net to find the surface area of a
prism.
Step-by-step explanation:
To find the total surface area of a prism, you need to calculate the area of two polygonal bases, i.e., the top face and bottom face. And then calculate the area of lateral faces connecting the bases. Add up the area of the two bases and the area of the lateral faces to get the total surface area of a prism.
Hope this helps!
All the love, Ya boi Fraser :)
Answer:
By drawing a net, you can see each face of the prism. You can find the areas of each face and then add them together to find the total surface area.

Ben is 12 years older than Ishaan. Ben and Ishaan first met two years ago. Three years ago, Ben was 4 times as
old as Ishaan.
How old is Ishaan now?
Answer:
Ishaan is now 6.
Step-by-step explanation:
If Ben is 12 years older, and you have the info that three years ago, he was 4 times as old, then all you have to do is divide 12 by 4, giving you 3. You add 3 to that because it's been three years. You have your answer of 6.
Hope this helps! :)
