Answer:

x = 0, 2

Step-by-step explanation:

{4}^{x}  - 5( {2}^{x} ) + 4 = 0 \\   {({2}^{x})}^{2}    - 5( {2}^{x} ) + 4 = 0 \\  {u}^{2}  - 5u + 4 = 0 \\ (u - 1)(u - 4) = 0 \\ u = 1 \: or \: u = 4 \\  {2}^{x}  = 1 \: or \:  {2}^{x}  = 4 =  {2}^{2}  \\ x = 0 \: or \: x = 2

The area of the shaded part is 52 sq. inches. The correct option is b. 52 sq. inches

<h3>Calculating Area</h3>

From the question, we are to determine the area of the shaded part

In the given diagram, the shaded part is a rectangle

Area of a rectangle = Length × Width

Length of the shaded part = 18 inches - 4 inches - 1 inch = 13 inches

Width of the shaded part = 6 inches - 2inches = 4 inches

Then,

Area of the shaded part = 13 inches × 4 inches

Area of the shaded part = 52 sq. inches

Hence, the area of the shaded part is 52 sq. inches. The correct option is b. 52 sq. inches

Answer:

1) x= -2

2) x= 3

3) x=7

4) x>5

5) x=-14

Step-by-step explanation:

1) −3x − 3 −7x = 17

−10x−3=17

−10x=17+3

−10x=20

x= -20/10

x=-2

2) 10x − 6 = 24

10x=24+6

10x=30

x= 30/10

x= 3

3) −4−5x=−39

−5x=−39+4

−5x=−35

x=-35/-5

x= 7

4) 3x - 5 > 10

3x>10+5

3x>15

x>​15/3

x>5

5)  -5 + x + 16 = -3

x+11=−3

x=−3−11

x=-14

Carl is boarding a plane. He has 2 checked bags of equal weight and a backpack that weight 4kg. The total weight of Carl’s bagga
garik1379 [7]

35 = 4 + 2b

2b = 35 - 4

b = backpack

35 - 4 = 31

2b = 31

Divide by 2

15.5 = b

Each bag weighs 15.5kg.

15.5 * 2 + 4 = 35

31 + 4 = 35

35 = 35
