Step-by-step explanation:

  • a = 2
  • b = 3
  • c = 5

\longrightarrow \rm{{\Bigg ( \dfrac{a}{b} \Bigg )}^c} \\  \\  \longrightarrow \rm{{\Bigg ( \dfrac{2}{3} \Bigg )}^5}  \\  \\   \qquad \qquad \bigstar \: \boxed{ \bf{  \Bigg ({\frac{x}{y} \Bigg )}^{m}  =  \frac{ {x}^{m} }{ {y}^{m}}   }} \\  \\  \longrightarrow \rm{ \frac{ {(2)}^{5} }{ {(3)}^{5} } } \\  \\ \longrightarrow  \bf{ \frac{ 32 }{ 243} }

Therefore, 32/243 is the answer.

F (a)=2a^2-16a+32<br> For which 'a' is this equation 0?
sergiy2304 [10]
If xy=0 assume that at leas 1 is zero
set it to zero

0=2a^2-16a+32
undistribute 2
0=2(a^2-8a+16)
2*0=0 so assume
a^2-8a+16=0
factor
(a-4)(a-4)=0
set to zero
a-4=0
a=4


when a=4, equation equals zero

What is value of x?
BlackZzzverrR [31]

(MAKE BRAINLIEST IF I HELPED)

Answer:

x=10

Step-by-step explanation::

We can use Triangle angle bisector theorem and proportions to solve this problem.  We put the small triangle side over the large triangle side

8           x+4

------ = ------------

12          2x+1

Using cross products

8(2x+1) = 12(x+4)

16x+8 =12x+48

Subtract 12x from each side

16x-12x +8 = 12x-12x+48

4x+8 = 48

Subtract 8 from each side

4x+8-8 = 48-8

4x = 40

Divide by 4

4x/4 = 40/4

x = 10
