Answer:

3r + 2s + 8t + 15

Step-by-step explanation:

7r + 10 - 2(2r + 3s - 5t) + 2(4s - t) + 5

=  > 7r + 10 - 4r - 6s + 10t + 8s   -  2t + 5

=  > 7r - 4r + 8s - 6s + 10t - 2t + 10 + 5

=  > 3r + 2s + 8t + 15

The diameter of a cylinder is 3yd the height is 8yd
nalin [4]

Answer:

volume= 56.55 yds

Step-by-step explanation:

If you're looking for the volume, the formula is V=\pi r^{2} h.

Diameter is two times the radius (radius is half of the diameter) so the radius of the cylinder would be 1.5 yds.

After you've gotten that information, plug those values into the formula.

V=\pi 1.5^{2} 8

Solve 1.5^2 first. Then multiply that value by pi. Then multiply that value by the height which is 8yds.

Volume=56.55yds rounded to the nearest hunderedth.

3n *power 2 +10n+7 how to factories and pls tell with solution
tankabanditka [31]

Answer:

(n + 1)(3n + 7)

Step-by-step explanation:

3n² + 10n + 7

Consider the factors of the product of the n² term and the constant term which sum to give the coefficient of the n- term.

product = 3 × 7 = 21 and sum = + 10

The factors are + 3 and + 7

Use these factors to split the n- term

3n² + 3n + 7n + 7 ( factor the first/second and third/fourth terms )

3n(n + 1) + 7(n + 1) ← factor out (n + 1) from each term

= (n + 1)(3n + 7) ← in factored form
