Answer:
steps below
Step-by-step explanation:
3 + 6b + 3b² = 3 (b² + 2b + 1) = 3 (b + 1)²
root: -1 if 3 + 6b + 3b² = 0 b = -1
Answer:
4. 12 in.
5. 3 in.
6. 3in per hour
7. slope would=3
Step-by-step explanation:
Remember that

simplify inside parentahsees first
1-1/4=3/4
1/3(3/4)^2=




2d^2 -2d-7
(14d^2 - 8) + (6d^2 - 2d + 1)
14d^2 - 8+ 6d^2 - 2d + 1
20d^2 - 7 - 2d
20d^2 - 2d - 7
Answer:
Step-by-step explanation:
Step 1: 6(x^2-1) [(6x-1)/(6(x+1)]
Step 2: [6(X+1) (X-1) (6X-1)] / 6(X+1)
Explanation: Factor out the (x^2-1)
Step 3: (6X-1) (X-1)
Explanation: Cancel out common terms on the top and the bottom of the fraction.
Step 4: 6X^2 - 6X-X+1
Explanation: Multiply out and Simplify
Answer: 6X^2 - 7x+1
