First set up the equation:
Then substitute in known values:
and solve for C
Answer:
a² + b²
Step-by-step explanation:
(a + b)² - 2ab ← expand parenthesis using FOIL
= a² + 2ab + b² - 2ab ← collect like terms
= a² + b²
Answer:
that is right
Step-by-step explanation:
because 4×4×4 equals 64 and 6×6 equals 37 so it is 4^3>6^2
40% is the answer because 6/15 = 0.4
It will take Mr. Jenkins 1 hr and 20 minutes to cut all the grass.
To know how long it will take Mr. Jenkins to cut all the grass, get the total area of the lawn and divide it by the rate Mr. Jenkins cut the grass.
The area of the lawn can be calculated using the formula for the area of a rectangle given by:
A = l x w
where l is the length and w is the width.
Using this formula, the grass lawn that is 24 m wide and 30 m long has an area of:
A = l x w
where
l = 30 m
w = 24 m
A = 30 m x 24 m
A = 720 m^2
Meanwhile, the time it will take Mr. Jenkins to cut the grass lawn with an area of 720 m^2 can be computed using the rate.
amount = rate x time
720 m^2 = 9 m^2/minute x t
t = 720 / 9
t = 80 minutes = 1 hr 20 minutes
