Answer:

The missing number would be 22.

Step-by-step explanation:

The missing number would be, lets say <em>x</em>.

(<em>x</em> - 8) / 7 = 2

First, lets multiply 2 by 7.

2 * 7 = 14

Next, lets add 8 to 14.

8 + 14 = 22

The missing number would be 22.

To check this answer, subtract 8 from 22 which would be 14.

Then divide by 7 which would be 2. This answer is correct.

Therefor, the missing number, or x, would be 22.

Hope this helps!

The square of the sum of two consecutive positive even integers is greater than the sum of their squares by 48. Find the two int

koban [17]

Answer:

4 and 6 or -6 and -4

Step-by-step explanation:

Let the numbers are 2x and 2x + 2.

(2x + 2x + 2)² = (2x)² + (2x + 2)² + 48
4(2x + 1)² = 4x² + 4(x + 1)² + 48
(2x + 1)² = x² + (x + 1)² + 12
4x² + 4x + 1 = x² + x² + 2x + 1 + 12
2x² + 2x - 12 = 0
x² + x - 6 = 0
(x - 2)(x + 3) = 0
x = 2, x = -3

<u>The numbers are:</u>

4 and 6 or - 6 and - 4

The covered part of this figure is a semicircle. What is the best approximation for the area of this figure?

zalisa [80]

Answer:

94.18

Step-by-step explanation:

Given in the question a semi circle and a right angle triangle

Step 1

Find the diameter of the semi circle

To find the diameter we will use pythagorus theorem

<h3>hypotenuse² = height² + base²</h3>

here,

hypotenuse will be diameter of semicircle

height = 9

base = 4

Plug values in the formula above

diameter = √(9²+4²)

diameter = √97

Step 2

Find radius

<h3>radius = diameter / 2</h3>

Step 3

Area

π(√97/2)²

= 76.18

Step 4

Total surface area = area of circle + area of right angle triangle

= 76.18 + 1/2(9)(4)

= 94.18
