Answer: 5x+6y+1 is the answer
Step-by-step explanation: to combine like terms that have to have the same variable so you can add them so for example you have 3x+2x which is equal to 5x then 2y+4y which is = to 6y and you also have 1 that isn't adding to anything because the others have variables
Answer: 111 dollars
Step-by-step explanation:
7 hours on Saturday and 4 hours on Sunday
Sunday gets paid 1 1/3, or 4/3 times more which is 9 x 4/3 = 12 per hour
Saturday is 9 per hour
7x9 (Saturday) + 4x12 (Sunday) = 111 dollars
Tan(60)/cos(45) = (sin(60)/cos(60))/cos(45)
= ((√3/2)/(1/2))/(√2/2) = (√3)/(√2/2) = (2√3)/(√2)
= ((2√3)(√2))/((√2)(√2)) = (2√6)/2 = √6

Marcus needs to bike at least 11 miles each day.
Step-by-step explanation:
Given,
Distance to cover = 80 miles at least
Distance already biked = 25 miles
Number of days left = 5
Let,
x be the distance to cover in 5 days.
According to given statement;
Number of days left * Distance to cover + distance already bike ≥ Total distance to travel
Dividing both sides by 5
Marcus needs to bike at least 11 miles each day.

To find zeros of this polynomial, set the poly = to zero and solve the resulting equation for x.
Please clarify this: does your "x4" mean x^4 (x to the 4th power), or something else?
Very important: for clarity use the symbol " ^ " to indicate exponentiation.
My educated guess is that by "<span>P(x) = x4(x − 2)3(x + 1)2" you actually meant
</span>
<span>P(x) = x^4(x − 2)^3(x + 1)^2, which is a 6th order polynomial.
</span>
Set this equal to zero and attempt to solve the resulting equation for x. You should expect to find up to six zeros (or solutions).
