Mathematics
1 answer:
zlopas [31]3 years ago
3 0

Answer:

s = -6.7

Step-by-step explanation:

- 16.68 + 1.8s + 2.2 = 3s - 6.4

- 16.68 + 2.2 + 1.8s = 3s - 6.4

- 14.48 + 1.8s = 3s - 6.4

Collect like terms

Note: crossing over equals to, the sign will change

Hint: either from

- to +

Or

+ to -

-14.48 + 6.4 = 3s - 1.8s

-8.08 = 3s - 1.8s

-8.08 = 1.2s

Divide both sides by 1.2, to get the value of s

-8.08/1.2 = 1.2s/1.2

-6.7 = s

s = -6.7

Which of the following correctly completes the square for the equation
rjkz [21]

Answer:

A. (x + 2)^2 = 31.

Step-by-step explanation:

x^2 + 4x = 27

x^2 + 4x - 27 = 0

A. (x + 2)^2 = 31

x^2 + 4x + 4 - 31 = 0

x^2 + 4x - 27 = 0

This option corresponds to the given equation, so it is correct.

B. (x + 2)^2 = 43

x^2 + 4x + 4 - 43 = 0

x^2 + 4x - 39 = 0

This does not correspond to the equation.

C. (x + 4)^2 = 31

x^2 + 8x + 16 - 31 = 0

x^2 + 8x - 15 = 0

This does not correspond to the equation.

D. (x+4)^2 = 43

x^2 + 8x + 16 - 43 = 0

x^2 + 8x - 27 = 0

This does not correspond to the equation.

So, your answer is A. (x + 2)^2 = 31.
