In can be less mental effort if the equation is multiplied by -1 first.
.. x^2 -10x +8 = 0
.. x^2 -10x +25 +8 -25 = 0
.. (x -5)^2 = 17
.. x -5 = ±√17
.. x = 5 ±√17

The values of x that satisfy the given equation are
.. x = 5 -√17 ≈ 0.877
.. x = 5 +√17 ≈ 9.123

You are standing in one big palace where a king and his 5 queens stay. Each queen has 5 rooms. In each room there are 5 big cats
Paladinen [302]
(5+1+1)*2 + 5*5*5*(1+5)*4 = 3014
Rooms = 5*5 = 25
Cats per room = 5 + 5*5 = 30
All cats legs = 25*30*4 = 3000
All humans = 1+1+5 = 7
All humans legs = 7*2 = 14
All legs = 3000 + 14 = 3014

Which equation represents the total commission (c) a sales associate receives if he sells 15 laptop computers (l)? What is the t
Leto [7]

Answer : C

the total commission (c) a sales associate receives if he sells 15 laptop computers (l)

Total commission = number of laptops * commission for each laptop

Total commission is c

number of laptops  is 15

commission for laptop is l

C = 15 * I

So c= 15l

the commission for selling each computer is $39.95

c= 15l

c = 15 * 39.95 = 599.25

3. Find the value of x and explain your reasoning<br><br> (4x - 8)<br> (3x + 10) (11x + 2y)º
jolli1 [7]

The question is an illustration of angles on a straight line

The value of x is 25.4

<h3>How to determine the value of x</h3>

In the figure, angles 1 and 2 are angles on a straight line

Where:

  • Angle 1 = 4x - 8
  • Angle 2 = 3x + 10

So, we have:

4x - 8 + 3x + 10=180

Collect like terms

4x  + 3x =180 - 10 + 8

7x =178

Divide through by 7

x =25.4

Hence, the value of x is 25.4

Find the measure of angle A If Angle A = 2x+18 and angle C = 3x+12
tatyana61 [14]

Answer:

Below in bold.

Step-by-step explanation:

2x + 18 + 3x + 12 = 180  (property of a cyclic quadrilateral).

5x = 180 - 18 -12

5x = 150

x = 30

So m < A = 2(30)+18

= 78 degrees.
