Answer:

18 x²- 45x .

Step-by-step explanation:

Given :  –9x(5 – 2x).

To find : What is the product.

Solution : We have given

 –9x(5 – 2x).

Distribute -9x over ( 5- 2x).

-9x  * 5 + 9x *2x.

What is the solution to the system of equations below?
disa [49]

The solution to the system of equation are x=2, y=0, z=6

<h3>System of equations</h3>

System of equations are equations that contains unknown variables.


Given the equations

3x+y+2z=8

8y+6z=36

12y+2z=12

From equation 2 and 3

8y+6z=36 * 1

12y+2z=12 * 3

______________

8y+6z=36

36y+6z= 36

Subtract

8y - 36y = 36 - 36

-28y =0

y = 0

Substitute y = 0 into equation 2

8(0)+6z=36

6z = 36

z = 6

From equation 1

3x+y+2z =8

3x + 0 + 2(6) = 8

3x = 8 - 12

3x = 6

x = 2

Hence the solution to the system of equation are x=2, y=0, z=6

Chord JK intersects chord ST at point L. Find the length of St. If necessary, round to the tenths place.
raketka [301]

Answer:

(C)19

Step-by-step explanation:

The diagram is drawn and attached.

Using the intersecting chord theorem

SL X LT = JL X LK

x X 12 = 14(x-1)

12x=14x-14

12x-14x=-14

-2x=-14

x=7

Therefore:

ST= SL + LT

=x+12

=7+12

ST=19

The correct option is C
