5. Which expression has a value that is greater than 840 ? 360 A (9 x 104) + (7 x 103) + (3 x 102) + (6 x 104)
B (8 x 105) + (7 x 103) + (3 x 102) + (6 x 104)
C (8 x 105) + (7 x 104) + (3 x 103) + (6 x 104)
D (8 x 105) + (7 x 104) + (3 x 102) + (6 x 104)

Consider the expression below. 9 + 4(x + 2) – 3.1 select the term that best describes "3" in the given expression. o a. coefficient variable exponent constant

[10 points, algebra 2]according to my answer key the restrictions are -1 and 4. but why not positive 1?

Someone answer asap for ! a ball is rolled down a ramp. the height, f(x), in meters, of the ball x seconds after it is released is modeled by the function f(x) = x²- 10x + 25 for all values of x from 0 to 5. which statement about the ball is true? a. the maximum height of the ball is 5 meters b. the height of the ball increases from 0 to 5 meters above the ground. c. the ball has traveled 5 meters when it reaches the bottom of the ramp. d. the ball has been traveling for 5 seconds when it reaches the bottom of the ramp
