PLZ HELP!!!
dexar [7]

Solution:

The given equation is:

3^2 x + 7^2= 2 ^x\\\\9 x +49 =2^x

A: Taking , x=1

L H S = 9 × 1  + 49 = 9 + 49= 58

R H S : 2^x=2^1=2

L H S ≠   R H S

B: Taking x=3

L H S = 9 × 3 + 49=27 + 49=76

R HS = 2^x = 2^3 = 8

L H S ≠  R H S

C: Taking x=5

L H S = 9 × 5 + 49

        = 45 + 49

       = 94

R H S:

2^x=2^5=32

L H S ≠ R H S

(D)

when , x= 8

L H S

9 × 8 + 49

= 72 + 49

= 121

R HS:

2^x=2^8 =256

L H S ≠ R H S

12345 [234]

Answer:

g - 16 is the answer

Step-by-step explanation:

−2 (3g−8g+8) − 9g

Distribute:

= (−2) (3g) + (−2) (−8g) + (−2) (8) + −9g

= −6g + 16g + −16 + − 9g

Combine Like Terms:

=−6g + 16g+ −16+ −9g

= (−6g+16g+−9g) + (−16)

=g+−16

Answer:

=g−16

In a chemistry class, 12 L of a 12% alcohol solution must be mixed with a 20% solution to get a 14% solution. How many liters of
tigry1 [53]
Let x = liters 20% solution to be added
then

.12(12) + .20x = .14(12+x)
.12(12) + .20x = .14(12+x)
1.44 + .20x = 1.68 + .14x
.20x = .24 + .14x
.06x = .24
x = 4 liters


Hope this helped!!
