Answer:
y = 36
Step-by-step explanation:
y = ax²
100 = a (5)² → 100 = 25a → a = 4
y = 4x²
x = 3 → y = 4(3)² = 36
Answer:
196, 245, 294
Step-by-step explanation:
sum the parts of the ratio, 4 + 6 + 6 = 15 parts
Divide the total by 15 to find the value of one part of the ratio
735 ÷ 15 = 49 ← value of 1 part of the ratio, thus
4 parts = 4 × 49 = 196
5 parts = 5 × 49 = 245
6 parts = 6 × 49 = 294
(2x - 5)(3x^2 - 4x +1)
6x^3 - 8x^2 + 2x - 15x^2 + 20x - 5
6x^3 - 23x^2 + 22x - 5
Answer:
3x/2x-1
