AVprozaik [17]3 years ago

Answer:

x = -0.8\ or\ x = 0.5

Step-by-step explanation:

Given [Missing from the question]

6x^2 + 2x - 2.5 = 0

Required

Solve

Using factorization, we have:

6x^2 + 2x - 2.5 = 0

Expand 2x

6x^2 - 3x+5x  - 2.5 = 0

Factorize

3x(2x - 1)+2.5(2x  - 1) = 0

Factor out 2x - 1

(3x +2.5)(2x  - 1) = 0

Split:

(3x +2.5) = 0\ or\ (2x  - 1) = 0

In both cases, solve for x

3x = -2.5\ or\ 2x = 1

x = -\frac{2.5}{3}\ or\ x = \frac{1}{2}

x = -0.8\ or\ x = 0.5 --- approximated

Complete the square to transform the quadratic equation into the form (x – p)2 = q.
ryzh [129]

The transformed equation is:

(x-3)^2 = 23

Step-by-step explanation:

We have to convert the equation in the form

(x-p)^2 = q

Given equation is:

x^2-6x-8 = 6

Adding 8 on both sides

x^2-6x-8+8 = 6+8\\x^2-6x = 14

In the given equation

a = x

b= ?

So,

2.x.b = 6x\\b =\frac{6x}{2x}\\b = 3\\

So 3^2 will be added on both sides

(x)^2-6x+ (3) = 14+ (3)^2\\(x-3)^2 = 14+9\\(x-3)^2 = 23

Hence,

The transformed equation is:

(x-3)^2 = 23

vova2212 [387]

Answer:

IT SHOULD BE 240

Step-by-step explanation:

1) Multiply 20 by 10 for 200

2) Lenght=20 so half is 10

3) multiply 10 by 4 and divide by 2 which gives 20

4) Multiply 20 by 2 because there are 2 rectangles which gives us 40

5) Add 200 and 40 which gives answer of 240

Westkost [7]

Matrix dimension 4x4. We put 1 if role is in relation with the collon (role is first number of (a,b), number a, and collone is number b. We have them 4). So, the matrix representation is:

0 0 1 1

0 1 0 0

0 1 0 0
