Answer:
Number of questions constraint:
x + y ≥ 15
Time constraint :
5x + 8y ≤ 120
Step-by-step explanation:
Let :
x = number of equations
y = number of word problems
Number of answers required = atleast 15
Equation takes 5 minutes
Word problem takes 8 minutes
Time available to complete exam = 120 minutes
Constraints :
Number of questions required
Total questions shout be atleast 15
x + y ≥ 15
Time constraint :
5x + 8y ≤ 120
I got d) not here. I solved it using my knowledge with angle relationships. I think the same rules apply with circles, but I am not 100% sure so please double check the math.
Answer:
Perimeter = 16x-20 units
Step-by-step explanation:
Given: 16x^2 - 40x + 25
Reduce perfect square trinomial: (4x-5)(4x-5)
4x-5 is your side length. Since the perimeter of a square is 4s, then the perimeter is 4(4x-5)=16x-20
