Answer:

56 degrees

Step-by-step explanation:

x+15 + x + 2x+1 = 180 (triangle angle sum theorem)

4x+ 16 = 180

4x= 164

x= 41

<C = x+15

x+ 41, so

41+ 15=

x+ 56

Answer:

$\frac{p^{-4}q^{5}r^{6}}{p^{-3}qr^{-2}}=p^{-1}q^{4}r^{8}$

Step-by-step explanation:

In division of powers with the same base, we must subtract the exponent of the denominator from the exponent of the numerator:

$\frac{a^{m}}{a^{n}}=a^{m-n}$

Then applying this to the problem:

$\frac{p^{-4}q^{5}r^{6}}{p^{-3}qr^{-2}}=p^{-4-(-3)}q^{5-1}r^{6-(-2)}$

Eliminating the parentheses:

$\frac{p^{-4}q^{5}r^{6}}{p^{-3}qr^{-2}}=p^{-4+3}q^{5-1}r^{6+2}\\ \frac{p^{-4}q^{5}r^{6}}{p^{-3}qr^{-2}}=p^{-1}q^{4}r^{8}$

what is the algebraic equation product of 3 and a squared number is twice the sum of the number and 4

Katyanochek1 [597]

Let n = number

" product of 3 and a squared number" translates to 3n²

"sum of the number and 4" translates to n + 4

The word "is" becomes your equals sign.

3n² = n + 4 is your equation.
