Answer:
7x^(2)-3x+8
Step-by-step explanation:
(5x^(2) - 3x - 2) - (-2x^(2) - +10)
(5x^(2))- (-2x^(2))=7x^(2)
(- 2)-(+10)=+8
7x^(2)-3x+8
Answer:
The degree of a polynomial is the largest exponent on one of its variables (for a single variable), or the largest sum of exponents on variables in a single term (for multiple variables).
Step-by-step explanation:
ere, the term with the largest exponent is , so the degree of the whole polynomial is 6.
Answer:
1/10
Step-by-step explanation:
Julie read 5/10 in the morning and had 4/10 left to read after what she read at night. At night, she read ...
1 - 1/2 -2/5 = 10/10 -5/10 -4/10 = 1/10
Julie read 1/10 of the book at night.
200 can be rounded down to 200, which is easy to add with. Thus, an estimate is 222+200=422.
Alternatively, you could round 222 up a bit, to get 225+200=425. This is actually the correct answer, but this rounding doesn't make the calculation easier, so if you needed a quick estimate I'd go with the first option.
Answer:
D
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
The square oh the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
h² = (9 )² + (9 )² = 162 + 162 = 324 ( take the square root of both sides )
h = = 18 → D
