Start with the given formula for the surface area of a sphere.

Now substitute 2x + 5 in for r, the radius.
Then simplify the expression and write it in standard form.

Answer:
in ur 4figure table fine tan 45 and mutiple it by 3 and find sin 60 and mutiple it by 4 ur answer mutiple it by what u got in tan 45 mutiple by 3
fin cos 30 and mutiple by 2 and sin 30 mutiple by 3 mutiple ur answers together
then finally what u got for the first on subtracted from ur second answer
Answer:
y + 12
Step-by-step explanation:
1. remove parentheses.
10 + 2 + y
2.collect like terms.
y + ( 10 + 2)
3. simplify.
y + 12
Therefor, the answer is. y + 12
(4y-3)(2y²+3y-5)
First , let's start with "4y"
4y*2y² = 8y³
4y*3y = 12y²
4y*-5 = -20y
Next, let's multiply by "-3"
-3*2y² = -6y²
-3*3y = -9y
-3*-5 = 15
Now, let's combine all of our values.
8y³+12y²-6y²-20y-9y+15 = 8y³+6y²-29y+15
