Answer: The second option (160 cm)
Step-by-step explanation:
1. You can obtain the perimeter of a quadrilateral by adding the lenghts of the sides.
2. You know that the ratio of the side lengths is 3:3:5:8 and the perimeter is 380 centimeters.
3. Therefore, you can write the following expression, where x is an integer:
4. Solve for x:
5. Therefore, the longest side is:
(160 cm)

Answer :
a = 1, b = -8, c = -5
Explanation
A standard form for the quadratic function is f(x) = ax2 + bx + c where the coefficients are a, b, and c.
The given quadratic function is f(p) = P2 - 8P - 5 When this function is compared to the standard form, with p replacing x, we obtain a = 1 because the leading term is 1*p2, b = -8 because the linear term is -8*p, c = -5 because the constant term is -5.
Answer is : a = 1, b = -8, c = -5.
ANSWER
Yes, the two expressions are equivalent.
The identity property of multiplication.
EXPLANATION
The identity element for multiplication of real numbers is 1.
This means that, if you multiply any real number by 1, you get the same real number
The given expression is,
These two expressions are equivalent.
The property that is applied is the identity property of multiplication.
Okay so like, all you've gotta do is multiply 567 by 48 & add 1250. Leaving you with the answer of 28,466
Let n = number of nickels, and p = number of pennies.
The number of coins is 25, so we get this equation.
n + p = 25
The value of the coins is 0.05 per nickel, and 0.01 per penny.
0.05n + 0.01p = 0.73
Now you have a system of equations.
n + p = 25
0.05n + 0.01p = 0.73
Solve the first equation for n:
n = 25 - p
Now substitute into the second equation.
0.05(25 - p) + 0.01p = 0.73
1.25 - 0.05p + 0.01p = 0.73
-0.04p = -0.52
p = 13
There were 13 pennies.
Now we substitute 13 for p in n + p = 25 to find out the number of nickels.
n + 13 = 25
n = 12
There are 13 pennies and 12 nickels.
Check: 13 pennies and 12 nickels does total 25 coins.
13 * 0.01 + 12 * 0.05 = 0.13 + 0.60 = 0.73
The value is $0.73.
Our answer is correct.
