Answer:

No

Step-by-step explanation:

If the factored form is (x + 6)(x - 3), then the two roots should be -6 and 3. Whatever the factored numbers are, the opposite sign should be the root in this situation, and vice versa.

Hope this helps!

What is the value of x? 3x−8=8x+4/2 Enter your answer in the box
krek1111 [17]

For this case we must find the value of "x" of the following expression:

3x-8 = \frac {8x + 4} {2}

Multiplying by 2 on both sides of the equation:

2 (3x-8) = 8x + 4\\6x-16 = 8x + 4

Subtracting 8x from both sides of the equation:

6x-8x-16 = 4\\-2x-16 = 4

Adding 16 to both sides:

-2x = 4 + 16\\-2x = 20

Dividing between -2 on both sides:

x = \frac {20} {- 2}\\x = -10

Answer:

x = -10

7) Rectangular pyramid:
Length = 8m ; width = 4.6m ; Volume = 88m³

Volume of a rectangular pyramid = (Length * Width * Height)/3
88m³ = (8m * 4.6m * height)/3
88m³ * 3 = 36.8m² * height
264m³ = 36.8m² * height
264m³ / 36.8m² = height
7.2 m = height

8) Cone:
r = 5 in ; volume = 487 in
³

Volume of a cone = π r² h/3
487 in³ = 3.14 * (5in)² * h/3
487 in³ * 3 = 3.14 * 25in² * h
1,461 in³ = 78.5 in² * h
1,461 in³ / 78.5 in² = height
18.6 in = height
