Can somebody please help me !!!!!!
Katarina [22]
So, looking at how many seniors there are, you can see that there are 35 of them. 25 are in sports, 5 are in music/drama, and 5 work. If you added them altogether, you get 35. Now, the chance of them being in sports is 25/35 chance/probability. You can simplify 25/35 because both of them are divisible by 5. 5 times 5= 25 and 7 times 5=35. Therefore, the answer is 5/7.

Algebraic expression and identity 1)simplify the following (3a+b)3 +(3a-b)3
mylen [45]

Answer:

(3a+b)^3+(3a-b)^3=54a^3+18ab^2

Step-by-step explanation:

Given: (3a+b)^3+(3a-b)^3

Formula: x^3+y^3=(x+y)(x^2-xy+y^2)

(x+y)^2=x^2+2xy+y^2

(x-y)^2=x^2-2xy+y^2

x\rightarrow 3a+b

y\rightarrow 3a-b

\Rightarrow (3a+b+3a-b)((3a+b)^2-(3a+b)(3a-b)+(3a-b)^2)

\Rightarrow (6a)(9a^2+b^2+6ab-9a^2+b^2+9a^2+b^2-6ab)

\Rightarrow (6a)(9a^2+3b^2)

\Rightarrow 54a^3+18ab^2
