(-2d² + s)(5d² - 6s)
Simplify.
(-2d² × 5d²) + (-2d² × 6s) + (s × 5d²) + (s × -6s)
Simplify.
-10d² + (-12d²s) + (5d²s) + (-6s²)
Take out the parenthesis.
-10d² - 12d²s + 5d²s - 6s²
Combine like terms.
-10d² + (-12d²s + 5d²s) - 6s²
Simplify.
-10d² - 7d²s - 6s²

Step-by-step explanation:
Solve for p by simplifying both sides of the equation, then isolating the variable
Answer:
Step-by-step explanation:
Isolate the variable by doing operations to both sides of the equation.
The work is shown below:
Using the probability concept, we have that:
- The probability that the student only plays football is: (c) 13 /33.
- The probability that the student plays baseball, but not football is: (d) 8/33.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
The total number of students is given by:
26 + 3 + 9 + 10 + 6 + 5 + 7 = 66
Of those, 26 play only football, hence the probability is:
p = 26/66 = 13/33
Which means that option c is correct for question 19.
Of those same 66 students, 9 + 7 = 16 play baseball but not football, hence the probability is:
p = 16/66 = 8/33
Which means that option d is correct for question 20.
