The correct answer to this question is letter "C. distance." An isometry is a transformation that preserves distance. Isometry is a geometrical transformation that preserves geometrical properties such as distance. In mathematics, an isometry (or congruence, or congruent transformation) is a distance-preserving injective map between metric spaces.
Answer:
a = - 5, a = - 3
Step-by-step explanation:
Given
a² + 8a + 15 = 0 ← in standard form
(a + 3)(a + 5) = 0 ← in factored form
Equate each factor to zero and solve for a
a + 3 = 0 ⇒ a = - 3
a + 5 = 0 ⇒ a = - 5
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

Answer:
Total number of copies sold till date are 381522.
Step-by-step explanation:
It is given in the question the book sold 35100 copies in its first month of release and this number is 9.2% of the number of copies sold till date.
To find is how many copies have been sold.
Let the total number of copies sold be = A
Therefore 9.2% × A = 35100
A = 381521.74 ≅381522 copies
