Answer:
-10b2+4b+2
Step-by-step explanation:
Answer:
x + x + x + x - 1 - 1 = x + x + x - 1 - 1 - 1 - 1 - 1
- 4x + ( - 2 ) = 3x + ( - 5 )
Step-by-step explanation:
2nd answer is the correct answer.
Answer:
2
Step-by-step explanation:
F(3) means that we plug in 3 for the x value of the original equation, and F(4) means that we plug in 4 for the x value of the original equation
F(3) = -2(3) + 3
= -3
F(4) = -2(4) + 3
= -5
- 3 -(-5) = 2
x = 7
∠ABD = ∠CBD = 20 ( BD bisects ∠ABC )
solve either 3x - 1 = 20 or 34 - 2x = 20
3x - 1 = 20 ( add 1 to both sides and divide by 3 )
3x = 21 ⇒ x = 7
OR
34 - 2x = 20 ( subtract 34 from both sides and divide by - 2 )
- 2x = - 14 ⇒ x = 7
