Answer:
D. 8x³ + 4x⁷ - 3x³ + 3x² - 2x + 9
Step-by-step explanation:
(8x⁸ - 9x³ + 3x² + 9) + (4x⁷ + 6x³ - 2x)
Apply distributive property to eliminate parentheses
8x⁸ - 9x³ + 3x² + 9 + 4x⁷ + 6x³ - 2x
Collect like terms
8x⁸ + 4x⁷ - 9x³ + 6x³ + 3x² - 2x + 9
8x³ + 4x⁷ - 3x³ + 3x² - 2x + 9
Answer:
A.
Step-by-step explanation:
First you need to get rid of the parenthesis by distributing the 0.6 to each term inside.
(0.6)(10n) + (0.6)(25) =10+5n
6n +15 = 10+5n subtract the 5n on both sides and subtract 15 from both sides
6n-5n = 10-15
n=-5
Answer:
FORMULA USED-
NUMBER OF SUBSETS OF A SET WITH n ELEMENTS= 2^n
Here our set is { onions, garlic, carrots, brocoli, shrimp, mushrooms, zucchini, green pepper}
Different variations available for ordering pasta with tomato sauce= 28 = 256 ( As here n= 8)
Answer:
Step-by-step explanation:
90 + 122 + 4x + 19 + 9x - 8 + 7x - 3 = 540
220 + 20x = 540
-220 -220
--------------------------
20x = 320
/20 /20
----------------
x = 16
