14. 2z^2 - 4z + 2 =0

First factor out a 2

2(z^2 - 2z + 1) = 0

Now factor the z^2

2(z - 1)(z - 1)

z = 1 , 1 A

15. x^2 +6x = 0

factor out an x

x(x + 6) = 0

X = 0, -6 B

16.

6x^2 - 17x -14 = 0

Factor

(2x - 7)(3x +2) = 0(use the diamond method so solve this)

x = 7/2 , -2/3 D

17.

Simplify

15x^2 - 14x - 8 = 0 (use the diamond method to factor)

(3x -4)(5x + 2) = 0

x = 4/3, -2/5 B

Solve open parentheses square root of 7 close parentheses to the 6 x power = 49x−6.
LUCKY_DIMON [66]
(sqrt7)^6x = 49x - 6

There is no easy way to solve this . Drawing a graph will give a good approximation.

Draw  y = (sqrt7)66x

and y = 49x - 6     and see where they intersect

Ill draw it on desmos graphing tool and give you the link.

Larry says 5 × 900 is less than 5 × 9,000. Doni says 5 × 900 is greater than 5 × 9,000. Which statements about the two products
BartSMP [9]

Answer:

Larry's statement is correct

Step-by-step explanation:

Larry says 5 × 900 is less than 5 × 9,000.

Doni says 5 × 900 is greater than 5 × 9,000.

5 × 900 = 4500

5 × 9000 = 45,000

45,000 is greater than 4500 because the place value of 45,000 is tens thousands and 4500 is Thousands.

Hence, Larry's statement is correct.(Larry says 5 × 900 is less than 5 × 9,000.)

How many solutions does the equation 4x + 8 = − 2 − 2 + 5x have?
ikadub [295]

Answer:

12 =x

There is one solution

Step-by-step explanation:

4x + 8 = − 2 − 2 + 5x

Combine like terms

4x+8 = -4+5x

Subtract 4x from each side

4x-4x+8 = -4+5x-4x

8 = -4+x

Add 4 to each side

8+4 = -4+4+x

12 =x
