Leo made a mistake in his calculation of the total area of the garden. The correct area of the garden is 1.2 meters x 3.5 meters = 4.2 square meters, not 4.20 square meters.
Therefore, the correct amount of fertilizer needed for the garden is 4.2 square meters x 0.075 kg/square meter = 0.315 kg. Leo incorrectly calculated it as 0.2150 kg.
A rectangular garden has a width of 1.2 meters and a length of 3.5 meters. For each square meter of space in the garden, Leo needs to use 0.075 kilogram of fertilizer. He finds the total amount of fertilizer needed for the garden using the work below.

Leo made an error finding the amount of fertilizer needed for the garden. He incorrectly multiplied 4.2 square meters by 0.0075 kg/square meter and found the partial product of 42 and 7.
The correct calculation for the amount of fertilizer needed is 4.2 square meters x 0.075 kg/square meter = 0.315 kg.
Therefore, Leo needs 0.315 kilogram of fertilizer for the garden.

Leo made an error finding the area of the garden. He incorrectly added 60 and 360 to get 4.20 square meters. The correct area of the garden is 1.2 meters x 3.5 meters = 4.2 square meters.
For the amount of fertilizer needed, Leo correctly multiplied 4.2 square meters by 0.075 kg/square meter and found the correct product of 0.315 kg.
Therefore, Leo needs 0.315 kilogram of fertilizer for the garden.
For the amount of fertilizer needed, Leo correctly multiplied 4.2 square meters by 0.075 kg/square meter and found the correct product of 0.315 kg.

The length of one side of a square is 3n + 2. The perimeter of the square is 4(3n+2). Which expression is equivalent to the perimeter?
12n+6
7n+6
7n+8
12n+8
12n+6
7n+6
7n+8
12n+8
The perimeter of a square is calculated by adding up the lengths of all four sides. Since all four sides of a square are equal, the perimeter of a square with side length 3n+2 would be 4 times that length.
Given that the side length is 3n+2, the perimeter would be:
4(3n+2)
= 4 * 3n + 4 * 2
= 12n + 8
Therefore, the expression equivalent to the perimeter of the square is 12n+8.
Given that the side length is 3n+2, the perimeter would be:
4(3n+2)
= 4 * 3n + 4 * 2
= 12n + 8
Therefore, the expression equivalent to the perimeter of the square is 12n+8.

Which best describes how to find an equation of the line shown?
The slope m is run/rise, so, x/y = m. Solve for y to get y = x/m
The slope m is run/rise, so x/y = m. Solver for x to get z = ym
The slope m is run/rise, so y/x = m. Solve for y to get y = mx
The slope m is run/rise, so x/y = m. Solver for x to get x = ym

The correct description for finding an equation of the line is: "The slope m is run/rise, so y/x = m. Solve for y to get y = mx."
This is because the slope of the line can be determined using the rise over run method, where the rise corresponds to the change in the y-coordinates and the run corresponds to the change in the x-coordinates. The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. By solving the equation for y, we get y = mx.

Eve was 9 when her brother Victor was born. Which equation tells you how to find Eve’s age if you know Victors age?
E = V - 9
E + V = 9
E = V + 9
V = E + 9
E = V - 9
E + V = 9
E = V + 9
V = E + 9
The equation that tells you how to find Eve's age if you know Victor's age is:
E = V + 9
This equation represents that Eve's age (E) is 9 years older than Victor's age (V).
E = V + 9
This equation represents that Eve's age (E) is 9 years older than Victor's age (V).
