Step-by-step explanation:
Simply combine like terms together:
-5x² - 3x - 7 - 2x³ + 6x² - 8
-2x³ + (-5x² + 6x²) - 3x + (-7 - 8)
-2x³ + x² - 3x + (-7 - 8)
-2x³ + x² - 3x - 15
Answer: -2x^3+x^2-3x-15
Step-by-step explanation:
As there is only addition and subtraction here, and the two groups of parenthesis are added, you can ignore the parenthesis.
Thus, simply combine like terms to get.
-2x^3+x^2-3x-15

If multiplying something with like bases, add the exponents together.
<span>a) It is Win with snowfall OR Win without snowfall = 32% + 41% = 73%
b) It is Snowfall on game day AND Win = 29% * 32% = 9.28%
c) It is 32% * 29% / 73% = 12.71 %</span>
So plug in the 5 for x. it would look like 7(5+4). you do PEMDAS and then looks like 7(9) and 7 multiplied by 9 equals 63.
