Answer:
The length is 20, and the width is 15.
Step-by-step explanation:
You have to write an expression to represent this situation. w can be the width, and the length can be 2w-10. To fnd the area, you multiply these together. w(2w-10) is 2w^2 -10w. From there, 15 is the only value of w that satisfies the equation, so w=15. Substitute 15 into your expression for lngth, and 2(15)-10 is 30-10 is 20, so the length is 20.
Answer:
3¼
Step-by-step explanation:
We take any of the two points shown in the question. I will take (-3, 1) and (1, 14).
x¹ = -3
y¹ = 1
x² = 1
y² = 14
Now, we sub these figures into the formula.
This leaves us with 14-1/1+3, which we can make into 13/4
13/4 = 3¼

To answer this problem, the utilization of the provided formula is of utmost importance.
The formula to be used would be for the combination with no repetition since it is what is asked and possibly happens when involving the products mentioned in the problem. The formula would be
n! where in
------------- n = number of things to choose from
(n - r)! r! r = number of things needed to form
the symbol ! is called a factorial function which replaces the sequence of multiplying a number in a descending order.
lets substitute and solve
13!
--------------
(13 - 6)! 6!
13!
-------------
(7!) 6!
6,227,020,800
-------------------
5,040 x 720
6,227,020,800
-------------------
3,628,800
1,716
The answer would be 1,716.
Answer:
C (let me know if I am wrong!)
Step-by-step explanation:
We need to solve the equation.
If 5x+y = -24, then -24 - 5x = y.
x+ 3(-24-5x) = -2
= -14x-72=-2
= -14x-72+72=-2+72
= -14x=70
= -5
If x = -5, then -5 + 3y = -2.
3y = -2+5
3y = 3
y=1
So the answer is C.
