Answer:
A. -8x⁷ + 18x⁵y⁵ - 12x²y⁴ + 27y⁸
Step-by-step explanation:
Given:
(2x⁵ + 3y⁴)(-4x² + 9y⁴)
Required:
Find an equivalent polynomial
Solution:
(2x⁵ + 3y⁴)(-4x² + 9y⁴)
Using distributive property of multiplication
2x⁵(-4x² + 9y⁴) + 3y⁴(-4x² + 9y⁴)
-8x⁷ + 18x⁵y⁴ - 12x²y⁴ + 27y⁸
There are no like terms to add or combine, therefore:
(2x⁵ + 3y⁴)(-4x² + 9y⁴) = -8x⁷ + 18x⁵y⁵ - 12x²y⁴ + 27y⁸
Answer:
Two geometric figures are similar if their corresponding angles are equal and their corresponding sides are proportional. A ratio is a fraction which compares two quantities. In two similar geometric figures, the ratio of their corresponding sides is called the scale factor.
Step-by-step explanation:
The number you are looking for is 995
Answer:
B
Step-by-step explanation:
- 9.2(8x - 4) + 0.7(2 + 6.3x) ← distribute parenthesis
= - 73.6x + 36.8 + 1.4 + 4.41x ← collect like terms
= -73.6x + 4.41x + 36.8 + 1.4
= - 69.19 + 38.2
Answer:
4 inches
Step-by-step explanation:
First, we find how much fits into one inch of soil. We do this by multiplying 4 by 3. This equals 12. For every 12 cubic inches, the soil will be one inch deep. We divide 48 by 12 to see how many inches deep is it. This equals 4. The soil is 4 inches deep.
