I hope this helps you. The answer is c
Answer:
3x² + 6x - 24 = 0
(3x - 6)(x + 4) = 0
x = -4 , x = 2 when y = 0
Step-by-step explanation:
3x² + 6x - 24 = 0
(3x - 6)(x + 4) = 0
Means
3x - 6 = 0 ⇒ 3x = 6 ⇒ x = 6 ÷ 3 = 2
x + 4 = 0 ⇒ x = -4
The Parabola which represents the quadratic equation intersects x-axis at
points (2 , 0) and (-4 , 0)
To find the average, you have to add all the numbers up and then divide by the amount of numbers you added together.
Equation: (86+87+91+x)/4=98
Solve for x:
86+87+91+x=98*4
264+x=392
x=392-264
x=128
The fourth number is 128
(5,4) because when you divide
Answer:
8xyz
Step-by-step explanation:
multiply all numbers and alphabets
- 288xyz, 2.360xyz, 3.648xyz
- find HCF of numbers and after multiply by xyz
- 288={2×2×2×31}
- 360={2×2×2×3×3×5}
- 648={2×2×2×3×3×3×3}
- HCF={2×2×2}xyz
- 8xyz
