Answer:
<h2>One of them i believe is 2 (3+4m) and another one is 6+8m</h2>
Step-by-step explanation: so for the first one you have your equation 18+4(m-3)+4m you take the second part and do 2(9+2(m-3)+2m) then after that you get 2(9+2m-6+2m) and you get you first answer 2(3+4m)
Your second probelm 6+8m you have your equation 18+4(m-3)+4m you do 18+4m-12+4 and you subtract all th likes terms so you get 6+8m
Hope this helps!
Combine like terms by adding their FACES (Coefficients)
1) 4c² - 4
2) 20m^4 + 6m
3) -6a³ - 19a² + 8a - 10
4) -10a² - 2b + 3ab³ + 4a²b² -5b^4 - 9a²b² - 12a³b + 15ab³ = -10a² - 2b + 18ab³ - 5a²b² - 12a³b - 5b^4
5) 5a³ - 5a²
Answer:
for the first question b,
it doesn't make sense for choice a to have -2 people in the car. You can't have a negative amount of people. For choice choice c, you can't have half a person, and for choice d, Ms. Valdez can only have under 5 people, not five people exactly.
for the second question I need to see the whole inequality, generally there is a variable, and all i see is <-1, which is invalid.
hope this helps, if it does like it pls!!
Step-by-step explanation:
Answer:
You set up an equation, using the trig function "tan" to find half of the roof (the equation would be tan(24) = 3.5/x, where x = 1/2 roof width)
Step-by-step explanation:
That would be the first step.
You solve the equation for x, and then multiply x by 2 to get the width of the roof.
