Answer:

<h2>19.596 feet</h2>

Step-by-step explanation:

Use the pythagorean theorem.

a^2 + b^2 = c^2

a = 20ft

c = 28ft

400 + b^2 = 784

b^2 = 384

b = 19.596

Identify the 34th term of the arithmetic sequence 2, 7, 12

torisob [31]

The equation is AN=A1+D(N-1) A1 being the first number (2) D being the difference (in this case 5) and N being the nth term to find (34) so here you have AN=2+5(34-1) then AN=2+5(33). the answer here is 167.

How do u solve 4p - 40 = 7(-2p + 2) ?

mr Goodwill [35]

Answer:

Simplifying

4p + -40 = 7(2p + 2)

Reorder the terms:

-40 + 4p = 7(2p + 2)

Reorder the terms:

-40 + 4p = 7(2 + 2p)

-40 + 4p = (2 * 7 + 2p * 7)

-40 + 4p = (14 + 14p)

Solving

-40 + 4p = 14 + 14p

Solving for variable 'p'.

Move all terms containing p to the left, all other terms to the right.

Add '-14p' to each side of the equation.

-40 + 4p + -14p = 14 + 14p + -14p

Combine like terms: 4p + -14p = -10p

-40 + -10p = 14 + 14p + -14p

Combine like terms: 14p + -14p = 0

-40 + -10p = 14 + 0

-40 + -10p = 14

Add '40' to each side of the equation.

-40 + 40 + -10p = 14 + 40

Combine like terms: -40 + 40 = 0

0 + -10p = 14 + 40

-10p = 14 + 40

Combine like terms: 14 + 40 = 54

-10p = 54

Divide each side by '-10'.

p = -5.4

Simplifying

p = -5.4

Which expression is equivalent to the expression below? StartFraction m + 3 Over m squared minus 16 EndFraction divided by Start

Kamila [148]

Option B: $\frac{1}{(m-4)(m-3)}$ is the correct answer.

Explanation:

The given expression is $\frac{(\frac{m+3}{m^2-16}) }{(\frac{m^2-9}{m+4} )}$

Simplifying the expression, we have,

$\frac{m+3}{m^{2}-16}\times\frac{m+4}{m^2-9}$

Factor the equations, $m^{2}-16\right$ and $m^{2}-9$ ,we get,

$m^{2}-16\right=m^{2}-4^{2}=(m+4)(m-4)$

$m^{2}-9=m^{2}-3^2=(m+3)(m-3)$

Substituting these factored expressions in the above expression, we have,

$\frac{m+3}{(m+4)(m-4)}\times\frac{m+4}{(m+3)(m-3)}$

Cancelling the common terms $m+3$ and $m+4$ , we get,

$\frac{1}{(m-4)(m-3)}$

Thus, the expression equivalent to $\frac{(\frac{m+3}{m^2-16}) }{(\frac{m^2-9}{m+4} )}$ is $\frac{1}{(m-4)(m-3)}$

Hence, Option B is the correct answer.
