Answer:

Step-by-step explanation:
Use KCF method for fraction division.
- Keep the first fraction.
- Change the division operation to multiplication.
- Flip the second fraction.


Combine like terms
move the like terms together (x^2 with x^2, x with x, number wiht numbers)
4x^2-2x^2-5x+x+4+8
2x^2-4x+12

In scalar multiplication, each component of the vector is multiplied by the scalar. The description is True.
Answer:
B. m∠RTS = 78°
Step-by-step explanation:
The sides GH and GI of ΔGHI have the same length, so their opposite angles, ∠I and ∠H will have the same measures. Call that measure "x".
The sum of angles in a triangle is 180°, so we have ...
24° +x +x = 180°
2x = 156° . . . . subtract 24°
x = 78° . . . . . . divide by 2
The triangle similarity statement tells you that ∠T will have the same measure as ∠I, which is x, or 78°.
m∠RTS = 78°
