(x²+3x-4)(x-5)
x³-5²+3x²-15x-4x+20
x³-2x²-19x+20
Answer:
x = 0
Step-by-step explanation:
The distributive property of multiplication states that a(b - c) = a(b) - a(c). We can apply that to the given equation.
3(2 - x) = 6
3(2) - 3(x) = 6 (Apply distributive property on LHS)
6 - 3x = 6 (Simplify LHS)
6 - 6 - 3x = 6 - 6 (Subtract 6 from both sides)
-3x = 0 (Simplify both sides)
(Divide both sides by -3)
x = 0 (Simplify)
Hope this helps!

- Radius: <em>r</em>
- Diameter: d = 2r
Step-by-step explanation:
<u>Step 1: Define</u>
Radius = 12 cm
<u>Step 2: Find diameter</u>
- Substitute: d = 2(12 cm)
- Multiply: d = 24 cm
∴ The statement is false and should be 24 cm as the diameter.
