The perimeter of a rectangle is the sum of all the sides. So
1300 = (2 x 400) + (2 x width)

Answer:
The cost of the fencing is $273
Step-by-step explanation:
* Lets explain how to solve the problem
- Sam is planning to fence his back yard
- Every side of the yard except for the side along the house is to
be fenced
- The fencing costs $3/yd and can only be bought in whole yards
- The side of his yard opposite the house measures 35 yd
- The other two sides of his yard are 28 yd
* Lets solve the problem
∵ The length of the yard is the sum of the sides whose to be fenced
∴ The length of the yard = 28 + 35 + 28 = 91 yd
∵ The cost of the fencing is $3 per yard
∴ The cost = 91 × 3 = 273
∴ The cost of the fencing is $273
Answer:
D
Step-by-step explanation:
The standard form for a parabola is ax^2+bx+c. In this equation, b=0 and c=0. For g(x), you would plug in your y-value that was given (which is 4) and you would plug in your x-value that that given (which is 1). Use PEMDAS. The correct answer is the one that is true.
A. g(x) = (4x)^2
4 = (4(1))^2
4 = 16. (not true)
B. g(x) = 1/4 x^2
4 = 1/4 (1)^2
4 = 1/4 (not true)
C. g(x) = 16x^2
4 = 16(1)^2
4 = 16 (not true)
D. g(x) = 4x^2
4 = 4(1)^2
4 = 4. (true --> correct answer)
The |x| operator means 'absolute value' or the positive value of the negative values. To help this make sense, here's a visual representation:
But,
Do you see what I mean? BTW, your answer will just be 8 + 8 or 16.
