-3(x² +2x-3)+3(x²+4x)​

Answers

Answer 1

6x + 9

I hope this helps!

Answer 2

Answer:

= 6x +9

Step-by-step explanation:

1. you need to multiply -3 by x² + 2x - 3

so you got -3x² -6x + 9

2. Then, you need to multiply 3 by (x²+4x)

= 3x² + 12x

3. -3x² - 6x + 9 + 3x² + 12x

4. then you need to solve with the same

= - 3x² + 3x²

= 0

= - 6x + 12x

= 6x

5. lastly you will got the answer.

# = 6x +9

Answer:

C

Step-by-step explanation:

Matrices can be multiplied together if the number of columns in the first matrix equals the number of rows in the second matrix.

A is of order (3 × 2) and B of order (2 × 3 )

Since the 2 in the first and the 2 in the second match , the matrices can be multiplied

The resulting matrix is of order (3 × 3 )

This is obtained from the first 3 in order of A and the second 3 in order of B

Then AB is defined and the resultant matrix is of order 3 × 3

The diagonals of a rhombus are 30cm and 16cm. Find its area, the length of a side and its perimeter.​

Answers

Answer:

Area = 1/2 × product of diagonalsso area = 1/2 × 30 ×16 = 240 cm²

also diagonals bisect each other at right angles so 1/2×30= 15cm,, 1/2× 16 = 8cm

therefore by pythagoras theorem,

[tex] {15 }^{2} [/tex]+ [tex]{8}^{2} [/tex]= [tex] {side}^{2} [/tex][tex] \sqrt{289 = side} [/tex]

side = 17

what is the Domain of this?

Answers

Answer: The domain is 3/7, -6, and 4.

Step-by-step explanation:

In the case of rational expressions, we can input any value except for those that make the denominator equal to 0 (since division by 0 is undefined). In other words, the domain of a rational expression includes all real numbers except for those that make its denominator zero.

As the other answer mentioned, x = -6 and x = 4 are not in the domain, since they both make the denominator equal to zero, and thus the overall expression undefined. But x = 3/7 is allowed, since f (3/7) = 0.

Every other real number is also acceptable.

In interval notation, the domain is then

[tex](-\infty,-6) \cup (-6,4) \cup (4, \infty)[/tex]

why is x^4 the largest perfect square of x^5

Answers

Answer:

Step-by-step explanation:

Because x^5 has 5 members. When you group them into 2 members each, there is one x left over. This is most easily seen if you try it with numbers.

The clearest way is to pick something that is not a perfect square to start with.

6 * 6 * 6 * 6 * 6

6^2 is a perfect square. It is grouped into 2 groups. Each one is a 6

So 6^2 = 36. 36 is a perfect square.

You should note that 6 ^3  is not a perfect square. One of the 6s is unmatched and you get a fraction when you square root 6^3.

6 * 6 * 6 = 216. The square root of 216 is 14.697... which goes on forever.

6^4 is a perfect square.

6^4 = 1296 The square root of 1296 is 36.

[tex] \frac{1}{2} x - \frac{1}{4} = \frac{3}{5} x + 2[/tex]

[tex]20( \frac{1}{2} x - \frac{1}{4} ) = 20( \frac{3}{5} x + 2)[/tex]

[tex]20 \times \frac{1}{2} x - 20 \times \frac{1}{4} = 20( \frac{3}{5} x + 2)[/tex]

[tex]10x - 20 \times \frac{1}{4} = 20 \times \frac{3}{5} x + 20 \times 2[/tex]

[tex]10x - 5 = 20 \times \frac{3}{5} x + 20 \times 2[/tex]

[tex]10x - 5 = 4 \times 3x + 20 \times 2[/tex]
