Step-by-step explanation:
the perimeter is all the sides added up whereas the area is length × width
area is measured in square units not perimeter
The perimeter does not measures in square units because area should be measured.
What is the perimeter?A perimeter refers to the closed path that encompasses or outlines and represents the two-dimensional shape or a one-dimensional length. The perimeter of a circle is known its circumference.
Therefore, we can say that the The perimeter does not measures in square units because area should be measured.

what is the slope of the line that passes through the points (-4,-4) and (9,4)
Answer:
8/13
Step-by-step explanation:
(−4,−4);(9,4)
(x1,y1)=(−4,−4)
(x2,y2)=(9,4)
Use the slope formula:
m=
y2−y1
x2−x1
=
4−−4
9−−4
Answer: 8/13
Step-by-step explanation:
[tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]
[tex]m = \frac{4 -(-4) }{9-(-4) }[/tex]
[tex]m = \frac{4 +4 }{9+4 }= m = \frac{8}{13 }[/tex]
Slope is 8/13
Factor the equation below.
f(x) = x2 + x - 20
Answer:
f(x) = (x+5)(x-4)
Step-by-step explanation:
Key skills used in this problem: Quadratic equations, factoring
1) The equation x^2 + x - 20 is factorable (meaning it can be facttored easily)
2) We need to find factors of -20 that add up to 1. This is because our ac (a term times the c term) is -20 and our b term (the coefficient for +x) is 1.
3) The two factors would be 5 and -4.
4) So it would be (x + 5)(x - 4) when factored
Hope you understood and have a nice day!! :D
Answer:
f(x)= (x+5)(x-4)
Step-by-step explanation:
First muliply the coefficient of the xsquared with the constant, in this case 1 × -20 = -20. Then figure out two factors of -20 that equal the coefficient of the stand-alone x when added together. In this case, that coefficient is 1. Factors of -20 that add to 1 are 5 and -4. Now simply take each of those numbers and shove them into parenthesis with an x.
Potato salad can be purchased at the grocery store for $2.58 per pound. If Michael wants to buy 2.5 pounds of potato salad, how much will it cost?
Answer: $6.45

What is 2 to the 400th power factorial?
Step-by-step explanation:
2^400=2^(2×200)
2^(2×200) =[2^(2) ]^200
Now, [2^(2) ]^200=4^200
The power of 2 in 400! is 397.
What is the method of determination of power of prime in Factorial ?Let p is the prime number whose power is to be found
Let n is the factorial number then
p in n! = (n /p) + (n/p²) +(n/p³) + .......
until Numerator < Denominator
and after division only the integer part is taken
Therefore to determine the power of 2 in 400!
2 in 400! = (400 /2) + ( 400 /2²) + (400 /2³) +(400 /2⁴) +(400 /2⁵) +(400 /2⁶) +(400 /2⁷) +(400 /2⁸) + above this N < D
2 in 400! = 200 +100 +50+25+12+6+3+1
2 in 400 = 397
Therefore the power of 2 in 400! is 397.

Which terms in the expression
5c + 8 + 12c are like terms
Answer:
Step-by-step explanation:
like terms are 5c and 12c because both have the same variable, c
Answer:
The terms 5c and 12c are like terms. They can both be added.
Step-by-step explanation:
It could be any number the variable has to stay the same and if there is none, it can’t be paired. Also watch out for problems like 12c + 5c^2. THey don’t have the same variable due to th ^2
Which expression is equivalent to
13c + 9f - 7f + 3c + 15 - 2
Expression 1: 16e + 2f + 13
Expression 2: 28e + 2f + 1
Expression 3: 22e + 8f + 1
Expression 4: 6e + 12f + 13
Answer:Sorry but none where c there e but no c .
But it would be 16c +2f +13 .

On what interval(s) of x is f(x) positive?
On what interval(s) of x is f(x) negative?
Answer:
Positive: (-2,1)
Negative: (-∞,-2) U (1,∞)
Step-by-step explanation:
The graph of the function f(x) is given in the figure. We can see some points like (-2,0), (-1,1), (2,-2), and many others.
Note the second value of each point (the value of y) is positive or negative. When it's positive, the graph is above the x-axis, when it's negative, the graph is below the x-axis. When it's 0, the graph crosses the x-axis.
To find the intervals of x where the function is positive, we only have to look into the zone where the graph is above the x-axis. It can be identified as the interval (-2,1).
Similarly, the function is negative in the interval (-∞,-2) U (1,∞)
The function f(x) is positive in the interval [-2, 1].
The function f(x) is negative the interval (-∞, -2) U (1, ∞).
The positive regions of a function f(x) are those intervals where the function is above the x-axis. It is where the y-values are positive (not zero).
To find the intervals of x where the function is positive,
In the interval [-2, 1] , the function f(x) is positive.
The negative regions of a function f(x) are those intervals where the function is below the x-axis. It is where the y-values are negative (not zero).
In the interval (-∞,-2) U (1,∞) , the function f(x) is negative.
y-values that are on the x-axis are neither positive nor negative. The x-axis is where y = 0.
when y = 0, x = -2, 1
Therefore, the function f(x) is positive in the interval [-2, 1] and negative in the interval (-∞,-2) U (1,∞).

Answer:
2
Step-by-step explanation:
Because 1 in 5 throws she get 1 in
Answer: We are given 3 out of 15, the best is to convert into a percent, [tex]\frac{3}{15}[/tex] is our fraction, now divide the numerator by the denominator 3÷15=.0.20. Now bump it up two digits, 20%. Now 20% of 15 is 3, we need to find 20% of 10, if 20% is 20 from 100, then 2 must be 20% of 10.
And your answer is 2 out of 10 tosses.
