The problem says that line TQ is 18 units. The little red line through TQ and TR means that both lines are the same, so TR also equal 18 units.

We can solve for x in the equation for TR :

2x+10 = 18
 Subtract 10 from each side:

2x = 8

Divide both sides by 2:
x = 4

Because TQ and TR are identical, RS and QS are also identical so we can replace X with 4 in the equation for QS:

9(4) -11 = 36 - 11 = 25

RS = 25 units.

The sum of two integers is -15. The product of the two integers is 54. What are those two integers a. -6 and -9 b. -6 and 9 c. 6
Bas_tet [7]
Let the two integers be x and y respectively

Hence;
x + y =  - 15 \\  \\ xy = 54
From the first equation ;
x =  - 15- y
Substitute into the third equation
( - 15 - y)y = 54
Open up the bracket
- 15y -  {y}^{2}  = 54
Take everything to the right hand side of the equation and you'll have a quadratic equation
0 = 54 + 15y +  {y}^{2}
Solve the quadratic equation and you'll have two roots
y=  - 6 \: or \: y= -9
Substitute for each value of y in the first equation
Therefore:
x  + ( - 6) =  - 15 \:  \\ or \\  \: x + ( - 9) =  - 15
x - 6 =  - 15 \\ or \\ x - 9 =  - 15
x =  - 15 + 6 \\ or \\ x =  - 15 + 9

x =  - 9 \: or \: x =  - 6
Therefore the answer is A

2(3x+4)=4x+12 i don’t understand please help me
Step2247 [10]

Answer:X=2

Step-by-step explanation:first you simplify the left side by multiplying the 2 with both numbers which gets you 6x+8=4x+12 then you can subtract 8 from 12 which gets you 6x=4x+4 then you subtract 4x from 6x which then gets you to 2x=4 and finally you divide the 2 from the 4 to get X alone which then gets you the answer of x= 2
