Answer:
The correct choice is D
Step-by-step explanation:
Value of X=20 and then to know the value of y we need to add
52+52= 104
360-104= 256
256÷2= 128
Y=128
distance = time * speed
1 mile = time * 3.5 miles /56 minutes
so time = 56 minutes/3.5 = 16 minutes
Answer:
29-12 is a 17 difference
52-29 is a 23 difference (adding 6 to the number 17)
81-52 is a 29 difference (adding 6 to the number 23)
116-81 is a 35 difference (adding 6 to the number 29)
Step-by-step explanation:
Answer:21
Step-by-step explanation:
x=length
x(x-6)=315
x^2-6x=315
x^2-6x-315=0
(x-21)(x+15)
x=21, x=-15
x cannot be negative so the only answer is 21
