Answer:
wrong
Step-by-step explanation:
(x²+2)(x+3)
x³+3x²+2x+6
Rate is the change in one variable in relation to another variable. Generally, rate is calculated as follows:
R = ΔV1/ΔV2
Where
R = Rate
ΔV1 = Change in variable 1
ΔV2 = Change in variable 2
In the current scenario,
ΔV1 = 250,000 m^3 of mulch applied
ΔV2 = 1 m^2 of garden space
Therefore,
Rate of applying much is, R = 250,000/1 = 250,000 m^3/m^2
It is a square based pyramid where,
Length (l)=9
Height (h)=10
Slant height (s)=11
For, volume (V) = 1/3 l^2*h
=1/3 9^2*10
=1/3 *810
=270
For, surface area = 2sl
= 2*11*9
=198
