What is the value of x?<br> What is the measure of angle QOR?<br> What is the measure of angle ROS?

Veseljchak [2.6K]

Answer:

x = 26

angle QOR = 31

angle ROS = 59

Step-by-step explanation:

$(x + 5) + (2x + 7) = 90\\ 2x + x + 5 + 7 = 90 \\ 3x + 12 = 90 \\ 3x = 90 - 12 \\ 3x = 78 \\ x = 78 \div 3 \\ x = 26$

Sub x in

$(x + 5) \\ 26 + 5 = 31$

and

$(2 \times 26 + 7) \\ = 52 + 7 \\ = 59$

Help!! I cant figure this out for some reason

Thepotemich [5.8K]

Answer:

x³ - 6x² + 18x - 10

Step-by-step explanation:

(f - g)(x) = f(x) - g(x)

= x³ - 2x² + 12x - 6 - (4x² - 6x + 4)

= x³ - 2x² + 12x - 6 - 4x² + 6x - 4 ← collect like terms

= x³ - 6x² + 18x - 10
