Explain the difference between perimeter and area.why do they measure?what type of units are they measured in?

1 answer:

4 0

Perimeter is the distance around an object / shape. Area is the amount of space within a 2 dimensional surface. For example the perimeter of a square would be the lengths of each side added together while the area would be how much space inside of it that it occupies. Area is measured in units squared, while perimeter is left in just units. In other words if the unit ( measurements ) are conducted in cm, then the area would be put in cm^2. The perimeter would just remain in cm.

I know it seems that alot of people like on here so people do their work but I really need help!!! I have a set of problems that

marshall27 [118]

Answer:

No Problem, I know That I personally can't stand it when people just give me the number. So another way to think of this problem is "How many 2/3 are in 3 cups." So try drawing 3 rectangles to represent 3 cups and then draw two lines inside those rectangles so that there are 3 rectangles inside each one and then shade in two of the smaller rectangles in a way that you can tell them all apart preferably different colors and then just count them.

Step-by-step explanation:

Hope this is enough to help you understand it, if not then feel free to ask for more info in the comments. :)

Please help guys! Find the zeros of the quadratic equation by factoring. x^2+4x-5=0

mr_godi [17]

Answer:

x = -5, 1

Step-by-step explanation:

To factor an equation, break the polynomial into two binomials which multiply to make it. Find two numbers that multiply to C and add to B from $ax^2 + bx + c$ .

-1 and 5 multiply to -5 and add to 4.

$x^2+4x-5 = (x+5)(x-1)$

The zeros are the factors set equal to 0 and solved.

(x+5) = 0

x=-5

(x-1) = 0

x=1

Write an equation in points-slope form of the line that passes through (7,-6) and has the slope m= 1/2

s2008m [1.1K]

Answer: point-slope form is $(y -y_{1} ) = m(x - x_{1} )$

9.5 -(-6) = 1/2(0-7)

Step-by-step explanation: You can get a y-intercept by substituting the x and y values from the given coordinate into the slope-intercept form and solve for b.

y = mx + b

-6 = 1/2(7) + b

-6 = 3.5 + b

-9.5 = b Slope-intercept equation for this question would be y = x/2 - 9.5

Then use the coordinates of the y-intercept to create the point-slope equation

(-9.5 -[-6]) = 1/2(0-7)
