Ah, good ol' substitution. You need to take the phrase y+2 and replace every x with it. Then solve for y.
y=(y+2)^3-4(y+2)^2-6(y+2)+8
What do you need help with?
Answer: False, True, False, True, True, True
Step-by-step explanation:
Points A, B, and C are coplanar since they're on the same plane but not on the same line.
Both BD and DE intersect since they both have a common point which is D.
The line BD connects both planes.
<em>First, you would multiply 2 x 16. </em>
2 x 16 = 32
<em>Using that number, subtract by 8. </em>
32 - 8 = 24
<em>Multiply 3 x 16. </em>
3 x 16 = 48
<em>Subtract the two numbers from step 2 and 3. </em>
48 - 24 = 24
Answer:
3(x + 1)(3 - x).
Step-by-step explanation:
(x + 3)^2 - 4x^2
Using the identity a^2 - b^2 = (a - b)(a + b), we have
(x + 3 - 2x)(x + 3 + 2x)
= (-x + 3)(3x + 3)
= 3(x + 1)(3 - x)
