Step-by-step explanation:
To multiply out brackets, you multiply the values within the bracket by the one outside one at a time.
For example, for the first one, you would do 2*a, which is 2a, then 2*3, which is 6. Since the 3 was positive, the answer would be 2a+6.
2x + 3y = 10
In the xy-plane, the graph of which of the following equations is perpendicular to the graph of
the equation above?
•y=-3/2x-10 •y=-2/3x+10 •y=2/3x+10 •y=3/2x-10
The graph formed by equation y= -2/3x+10 will be perpendicular to the graph by equation y=3/2x-10.
What is the slope of any line?A line in the form of ax + by + d = 0 will be a linear equation and if we convert it into the form of y = mx + c where m will be the slope of that equation.
If two lines are perpendicular to each other then the product of their slope of them will be (-1).
⇒ m₁ ₓ m₂ = -1
The slope of line 2x + 3y = 10 will be -2/3
To be any line perpendicular whose slope m with the 2x + 3y = 10
⇒ -2/3 × m = -1
⇒ m = 3/2 so the slope of that line should be 3/2
Hence, line y=3/2x-10 will be perpendicular to the 2x + 3y = 10.

In the 1951 science fiction movie classic The Thing from Another World, a group of scientists and soldiers discover a recently crashed alien spaceship buried under a few feet of ice near the North Pole. The party spreads out to determine the size and shape of the alien craft under the blurry ice with the following dialogue: "It's perfectly round...yep, we finally found one...a flying saucer." Assuming that each of the 10 person party is exactly 68 inches (5'8") tall, what would be the diameter of the saucer be in feet rounded to the nearest foot?
Please note that there is insufficient information required to complete this task. The calculation of the diameter of the saucer would have been possible if we were given the width of the 10-person party not their height.
What is the formula for calculating diameter?The formula for calculating the diameter of a circular object in relation to circumference is given as the Circumference of an object divided by Pi (π). That is
If the width of the men were given, and they had stood around the saucer as close to each other as they could, then the circumference of the saucer would have been estimated as:
10 * (width of the men). = 10X
Diameter becomes = 10X/π
Remember, the answer must be in feet.

ABCD is a rectangle that represents a park. The lines show all the paths in the park. The circular path is in the center of the rectangle and has a diameter of 15
Complete Question:
ABCD Is a rectangle that represents a park.
The lines show all the paths in the park.
The circular path is in the centre of the rectangle and has a diameter of 15m.
Calculate the shortest distance from A to C across the park,using only the lines shown.
*See attachment for the diagram showing the paths in the park.
Answer:
Shortest distance from A to C through the paths only = 102.9 m
Step-by-step explanation:
Length of park = 80 m
Width of park = 50 m
Diameter of the circular path in the center of the park = 15 m
Therefore:
Shortest distance between from A to C across the park if we're to follow only the lines showing the oaths would be = (length of diagonal AC - diameter of the circular path) + (½ of the circumference of the circular path)
✔️Use pythagorean theorem to find AC:
AC = √(80² + 50²) = √8,900
AC = 94.3398113 ≈ 94.34 m (nearest hundredth)
✔️Diameter of circular path = 15 m
✔️½ of the circumference of the circular path = ½(πd)
d = 15 m
½ of the circumference = ½(π*15) = 23.5619449 ≈ 23.56 m (nearest hundredth)
✔️Shortest distance = (94.34 - 15) + 23.56 = 79.34 + 23.56 = 102.9 m

Point A is located at (-4,\ 9)(−4, 9) on the coordinate plane. Point B is located at (-4,\ -7)(−4, −7). What is the distance between Point A and Point B?
Answer:
AB = 16 units
Step-by-step explanation:
Given the coordinate (-4, 9) and (-4, -7)
Using the formula for calculating the distance between two points
AB = √(x2-x1)²+(y2-y1)²
AB =√(-7-9)²+(-4+4)²
AB = √(-16)²+0²
AB = √16²
AB = 16 units
Hence the distance between Point A and Point B is 16 units

A line plot with Kelly's ribbon lengths is shown .she adds two more ribbons so that the total length of ribbon is 200 inches . What are two possible lengths of ribbon, in inches , that Kelly could have added
Answer: (I changed it back to fraction form instead of decimal because it seems that is how you are doing it)
Two possible lengths of ribbon (In inches) are 25 and 133 3/4
Step-by-step explanation:
Okay, so- First, You need to find out how much ribbon is there before the two additional ones are added. Like this:
12 + 14 2/4 + 14 3/4 = 41 1/4
Next, subtract that amount from 200 to get the number of inches of ribbon that are needed to get 200 inches of ribbon. Like this:
(I changed it to a decimal to make it easier, so don't mind that)
200 - 41.25 = 158.75
So, 158.75 inches of ribbon are needed to get 200 inches. You can subtract any number less than 158.75 from that to get two seperate ribbon measurements.
(This might sound confusing so here)
For example:
158.75 - 25 = 133.75 (The bolded numbers are the two measurements)
158.75 - 65 = 93.75
So, Two possible lengths (in inches) of ribbon that kelly could have added are "25" and "133.75 "
Two possible lengths (in inches) of ribbon that kelly could have added are also "65" and "93.75"
