Answer: B. 12 and 64
Step-by-step explanation:
Option A is incorrect because the highest common factor for both numbers would be 38 not 4.
Option B:
Factors of 12 are: 1, 2 , 3, 4, 6, 12
Factors of 64 are: 1, 2, 4, 8, 16, 32 and 64.
<em>Highest factor of both is 4 and they both add up to 76 so option B must be correct. </em>
The answer for this question is C.
Answer: 30x⁴
Step-by-step explanation:
2x⁴ + (-3x²)² + 10(x²)² + (-3x²)²
2x⁴ + (9x⁴) + 10 (x⁴) + (9x⁴)
2x⁴ + 9x⁴ + 10x⁴ + 9x⁴
2x⁴ + 10x⁴ 9x⁴ + 9x⁴
12x⁴ + 18x⁴
30x⁴
(-x)² = x²
(xᵃ)ᵇ = xᵃᵇ
