Answer:

  • B and D

Step-by-step explanation:

<u>Solve the equation by completing a square:</u>

  • x² + 2x - 6 = 0
  • x² + 2x + 1 - 7 = 0
  • (x + 1)² = 7
  • x + 1 = ±√7
  • x = -1 ± √7

<u>Correct choice:</u>

  • B and D

I really need help so please help me out
AnnyKZ [126]

Answer:

The answer is option 2.

Step-by-step explanation:

Given that the TU and UF added up together to form a length of 32. In order to find TU, you have to subtract length of UF from 32 :

TU + UF = 32

TU + 20 = 32

TU = 32 - 20

TU = 12

What the answer to this all of those
zvonat [6]
So much stuff at once...
I'm only going to give you the information needed to do this.

All of these involve the 4 main exponent laws.

1) Multiplying.
    When you multiply two 'numbers' that share the same base, you add               exponents and keep the base the same. (ex. 4g²(4g⁴) = 4g²⁺⁴ = 4g⁶)

2) Dividing.
    When you divide two 'numbers' that share the same base, you subtract      exponents and keep the base the same. (ex. 3a⁷ / 3a⁴ = 3a⁷⁻³ = 3a³)

3) To the power of 1.
    Anything to the power of 1 is the same. (ex. 5a¹ = 5a)

4) To the power of 0.
    Anything to the power of 0 = 1. (ex. 2d⁰ = 2(1) = 2)

This should help.
