Factor each expression 36abc +54ad

olya-2409 [2.1K]

Answer:

18a(2bc + 3d)

Step-by-step explanation:

36abc + 54ad

Step 1: Find the Highest Common Factor of each

36abc = 2×2×3×3×a×b×c = 18a × 2bc

54ad = 2×3×3×3×a×d = 18a × 3d

HCF = 2×3×3×a = 18a

Step 2: Factor out with HCF

18a(2bc + 3d)

V=pi r^2 h solve for pi<br><br>please help asap<br>will mark brainliest

kogti [31]

Answer:

$\pi=\frac{v}{hr^2}$

Step-by-step explanation:

So we have:

$v=\pi r^2h$

And we want to solve for π.

First, divide both sides by h:

$\frac{v}{h}=\pi r^2$

Now, divide both sides again by r²:

$\pi=\frac{v}{hr^2}$

And this is our answer :)

FIRST TO ANSWER GETS BRAINLIEST! A, B, and C are polynomials, where A = n, B = 2n + 6, and C = n2 – 1. What is AB – C in simples

denis23 [38]

Answer:

$n^2+6n+1$

Step-by-step explanation:

AB would be (n) * (2n + 6). We need to distribute the n, so we multiply the n by each term within the parentheses and add those products together:

AB = $n(2n+6)=2n^2+6n$

C is just $n^2-1$ , and we subtract this from $2n^2+6n$ :

$2n^2+6n-(n^2-1)=2n^2+6n-n^2+1=n^2+6n+1$

Thus, the answer is $n^2+6n+1$ .

Hope this helps!
