Solve 2x^2=11x+6 by factoring

Answers

Answer 1

Answer:

Answer:

(x-6) (2x+1)

Step-by-step explanation:

1) move everything over to the left side, so subtract 11x and 6.

2x^2 -11x - 6 = 0

2)multiply 2(a term) with -6 (c term)

x^2 -11x -12

3) factor and find what multiples to -12 and adds up to -11. in this case its -12 and positive 1

(x-12) (x+1)

4) divide -12 and 1 by the original a term (2)

(x-6) (x+1/2)

5) move the denominator of 2 over to the x.

(x-6) (2x+1)

Completing The Square:

x² - 6x - 16 = 0

Here,

a = 1

b = -6

c = -16

Now,

x² - 6x + [6/2(1)]² - [6/2(1)]² - 16 = 0

x² - 6x + (6/2)² - (6/2)² - 16 = 0

x² - 6x + (3)² - (3)² - 16 = 0

(x - 3)² - 9 - 16 = 0

(x - 3)² - 25 = 0

(x - 3)² = 25

x - 3 = +-√25

x - 3 = +- 5

x = 3 +- 5

x = 3 + 5 or x = 3 - 5

x = 8 or x = -2

Answer:

Step-by-step explanation:

During the election for class president 40% of the students order for Jennifer and 60% of the students voted for Kevin 300 students voted in total how many more students voted for Kevin than .Jennifer

Answers

40%=4/10=4*(1/10)

60%=6/10=6*(1/10)

-----------------------------

1/10 of 300 is 30, therefore 4/10 of 300 is 120.

-------------------------------

1/10 of 300 is 30, therefore 6/10 of 300 is 180.

-----------------------------

So, 120 students voted for Jennifer and 180 students voted for Kevin therefore, Kevin received 60 more votes.

40% of 300 = 300 * 0.4 = 120 students for Jennifer
60% of 300= 300 * 0.6= 180 students for Kevin

180=120= 60 more students voted for Kevin

Why is it not possible to draw a square that is not a parallelogram

Answers

So a square is a parallelogram with four sides of equal length and angles of equal size. In other words, all squares are parallelograms, but only some parallelograms are squares.

because just because they have 4 sides and equal length doesn't mean that all squares are parallelogram.

The total cost (c) is proportional to the number of pineapples (n) purchased. The price of each pineapple is $4. Which equation represents the total cost of the pineapples purchased?A) c = 4n
B) n = 4c
C) c =
n
4
D) c =
4
n

Answers

Answer:

4. c = 4n.

Step-by-step explanation:

The total cost = price of 1 pineapple * the number of pineapples bought.

C =4n which represents the total cost

Harry and Terry are each told to calculate 8−(2+5)8−(2+5). Harry gets the correct answer. Terry ignores the parentheses and calculates 8−2+58−2+5. If Harry's answer is HH and Terry's answer is TT, what is H−TH−T?

Answers

Harry's Answer:
8-(2+5)8-(2+5) = 8-(16+40)-(2+5) ⇒ 8 - 16 - 40 - 2 - 5 = -55

Terry's Answer:
8 - 2 + 58 - 2 + 5 = 67

H = -55
T = 67

H - TH - T

-55 - (67*-55) - 67 = -55 - (-3685) - 67 = -55 + 3685 - 67 = 3,563
