A. The answer is 4y+3 you distribute and get 4y^2 +4y+1-4y^2+2 then combine like terms which is (4y^2-4y^2)+(4y)+ (1+2) and equals 4y+3
B. The answer is 14w^3 +2w^2 bc you distribute again which gives you 20w-10w^2-6w^3+12w^2 and then combine like terms (20w^3-6w^3)+(-10w^2+12w^2) and equals to 14w^3+2w^2
C. The answer is 3y^2-5y+2 bc you distribute again which is 7y^2-3y-4y^2-2y+2 and then combine like terms (7y^2-4y^2)+(-3y-2y) +2 and gives you 3y^2-5y+2
Hey there! :)
Answer:
r ≈ 4.38 cm.
Step-by-step explanation:
Find the radius by working backwards using the equation A = πr²:
Given:
A = 60.24 cm²
π = 3.14
Plug these into the equation:
60.24 = 3.14r²
Divide both sides by 3.14:
19.185 = r²
Take the square root of both sides:
r ≈ 4.38 cm.
Answer:
7x
Step-by-step explanation:
To purchase 7 tickets at the same rate ;
Mathematically, Total Cost of an item is :
Cost = unit price * quantity
Here,
quantity = 7 tickets
Since price per ticket(rate) is the same ; then we can take rate as x
Hence, the cost of the 7 tickets is :
Quantity * rate
7 * x = 7x
Hi! So this is just a simple probability question that seems a lot more complicated than it actually is. To find the probability that they only play clarinet, all you have to do is take 182 and subtract 86 because it eliminates the people that also play the flute. After doing this, you put your answer (96) and put it over the total amount of people (350). There for there is a 96 in 350 chance that they will only play clarinet.
Answer:
Your final answer will be, x^2 +4x -12
