Answer:
90
Step-by-step explanation:
Evaluate x^2 + 2 x^2 + 3 x^2 + 4 x^2 where x = 3:
x^2 + 2 x^2 + 3 x^2 + 4 x^2 = 3^2 + 2×3^2 + 3×3^2 + 4×3^2
3^2 = 9:
3^2 + 2×9 + 3×3^2 + 4×3^2
3^2 = 9:
3^2 + 2×9 + 3×9 + 4×3^2
3^2 = 9:
3^2 + 2×9 + 3×9 + 4×9
3^2 = 9:
9 + 2×9 + 3×9 + 4×9
2×9 = 18:
9 + 18 + 3×9 + 4×9
3×9 = 27:
9 + 18 + 27 + 4×9
4×9 = 36:
9 + 18 + 27 + 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
