Answer:

AC < BC < AB

Step-by-step explanation:

Given: BC = 118

AB = 63*2 = 126

AC = 360 - (BC+AB)

AC = 360 - (118+126) = 116

Which is the value of this expression when a=5 and k=-2

Zinaida [17]

Answer:

Option C is correct.

Step-by-step explanation:

We are given the expression:

$(\frac{3^2a^{-2}}{3a^{-1}})^k$

The value of a =5 and k = -2

Putting the values and solving

$=(\frac{3^2*5^{-2}}{3*5^{-1}})^-2\\=(\frac{3^{2-1}}{5^{-1+2}})^-2\\=(\frac{3^{1}}{5^{1}})^-2\\\\=(\frac{3}{5})^-2\\if \,\,a^{-1} \,\,then\,\, 1/a\\=\frac{(3)^{-2}}{(5)^{-2}}\\ Can\,\,be\,\,written\,\,as\\\\=\frac{(5)^{2}}{(3)^{2}} \\=\frac{25}{9}$

Option C is correct.

Using complete sentences, write an indirect proof proving that if x=30, then 3/4x+5≠20 (3/4 being three over four)

WARRIOR [948]

<span>hypothesis :-
if x=30, then 3/4x+5≠20
let Q:- x=30 P:- 3/4x+5≠20
we need to prove if Q then P (Q →P)

proof :-
lets assume 34x+5=20 is true
now x=30
so
3/4(30)+5=27.5 ≠20
which is a contradiction

Please help me solve this... I will mark you brainliest if it’s correct

Crank

(5 + 7x + 6)/2 = 3x + 9

7x + 11 = 6x + 18

7x - 6x = 7

x = 7

EF = 3x + 9

= 3(7) + 9

= 21 + 9

= 30
