Answer:

a) x=10

b) x=7

Step-by-step explanation:

a)

2x-7=13

<em>Add 7 to both sides</em>

2x=20

<em>Divide both sides by 2</em>

x=10

b)

3x+4=25

<em>Subtract 4 from both sides</em>

3x=21

<em>Divide both sides by 3</em>

x=7

Can someone please help ASAP
White raven [17]

Answer: 36

Step-by-step explanation:

Multiply -6 by itself six times, then divide 1 by -6 four times. Multiply the products. Then multiply -6 by itself one more time and you will get 36.

The top question is 1/4. There seems to be a small multiplaction symbol next to the fractions, I'm ignoring that. To get 1/4, I multiplied 2 by itself six times because of the exponent, to get 64. I did the same with the bottom, and recieved 256. 64/256 is 1/4.

The percentage of the area inside the square that is shaded is 55%.

<h3>What is the perimeter of the square?</h3>

The perimeter of the square is 20Cm

Each side of the square is = 5Cm

Area = ( Length x Width )

(5 x 5) = 25 =Area

Area = 25

Area of triangle 1 = (1/2) x 5 x (5 - 3) = 5 cm²

Area of triangle 2 = (1/2) x 5 x (5 - 3.5) = 6.25 cm²

Area of shaded portion = 25 - (5 + 6.25) = 13.75 cm²
