Setler79 [48]

There is no two numbers that can add to 10 and multiply to 28, the highest number you can get by multiplying numbers that add to equal 10 are 5 and 5, and that only reaches 25. I'm sorry

What is the solution to 9x−6<21?

Alisiya [41]

Answer:

$x > 3$

Step-by-step explanation:

1) Add 6 to both sides.

$9x > 21 + 6$

2) Simplify 21 + 6 to 27.

$9x > 27$

3) Divide both sides by 9.

$x > \frac{27}{9}$

4) Simplify 27/9 to 3.

$x > 3$

To solve the exercirses which are shown in the figure attached, you must follow the proccedure below:

7) (x)=x³-6x²+8x
(x)=x(x³-6x²+8)
(x)=(x-4)(x-2)x

The lenght is: x
The height is= (x-4)

8) √(2x+8)-6=4

1. You need to clear the variable "x". Then:

√(2x+8)=4+6
√(2x+8)=10
(√2x+8)²=10²
2x+8=100
2x=100-8
x=92/2
x=46

9) l4x+3l=9+2x

1. To solve the left member, you must evaluate two cases: it could be positive,or negative. Then:

2. Negative:

l4x+3l=9+2x
-4x-3=9+2x
-4x-2x=9+3
-6x=12
x=12/-6
x=-2

3. Positive:

l4x+3l=9+2x
4x+3=9+2x
4x-2x=9-3
2x=6
x=6/2
x=3
