9. The function f(x) has a zero of 2 with multiplicity 3. We know... a) since 3 is an odd number, the graph touches but does not cross the x-axis.
b) since 3 is an odd number, the graph crosses the x-axis.
c) since 2 is an even number, the graph touches but does not cross the x-axis.
d) since 2 is an even number, the graph crosses the x-axis.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
