The area of a rectangular flower garden is given by the expression x2 – 25x +150. If the length of the garden is given
by the expression x - 15, what is the width of the garden?

w = ( x - 10)

Step-by-step explanation:

area of the garden = x² - 25x + 150.

factorise the expression to find the x values.

x² - 25x + 150 = (x - 15)( x - 10) -15-10 = -25

-15*-10= 150

as the garden is rectangle, it's area will be = lw.

a = l × w

a = (x - 15)( x - 10)

one among them is the width, the other the length. if the length is (x - 15), then reasonably the width will be (x - 10).

hope this helps you, au revoir!

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
