FOR 47 POINTS PLEASE HELP QUESTION 1
If RS is 2x+15, and VW is 3x+5, and UT is 6x-37. What is RS?

QUESTION 2
Angle J is (7x+2) Angle L is (25x-14)
What is (x)

UV=25 units

Step-by-step explanation:

we know that

UW=UV+VW > by addition segment postulate

substitute the given values

4x+10=5x+5

solve for x

5x-4x=10-5

x=5

Find the value of UV

UV=5x

substitute the value of x

UV=5(5)=25 units

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form
