Answer:
a) 4x - 8y
b) 4 × x - 8 × y
c) 4x - 8y is the same as 4 × x - 8 × y because if there is no simbol then it is always multiplication
Step-by-step explanation:
a) start with the parentheses
1/3 (6x - 12y)
multiply 6x and -12y by (1/3)
2x - 4y
so now the equation is 5x -3x -4y + 2x -4y
add together the like terms
5x -3x + 2x = 4x
-4y -4y = -8y
so we have 4x - 8y
b) im not good with factored form but i believe this is right
take 4x and separate them by turning it into 4 × x and same for -8y turn it into -8 × y
c) 4x - 8y is the same as 4 × x - 8 × y because if there is no simbol then it is always multiplication
im not sure how to prove them equal to the original expression i dont really remember that but i hope this helped
Answer:
Step-by-step explanation:
Since the land is a round enclosure, and it has 2.5 foot wide enclosure of pebbles surrounding, then the circumference of the garden is 2.5ft.
First we need to get the diameter of the garden using the formula;
Circumference= πd
2.5 = πd
d = 2.5/π
d = 2.5/3.142
d =0.796 feet
The total area of a round section of the land = πd²/4
The total area of a round section of the land = π(0/796)²/4
The total area of a round section of the land = 1.9892/4
<em>The total area of a round section of the land = 0.4973 ft²</em>
