Answer: (x - 4) • (3x + 2)
Step-by-step explanation:
Answer: a. 3.4t (miles)
b. 2.125 miles
c. t = 1.6 hours
Step-by-step explanation:
A) We will use the relation:
Distance = Speed × Time
Distance= 3.4 × t
= 3.4t (miles)
B) If t= 5/8
Distance d= 3.4 × 5/8
= 3.4 × 0.625
= 2.125 miles.
C) If the distance d= 5.44,
Time will be:
d= 3.4t, and we know that d=5.44
Therefore, 5.44 = 3.4t
t = 5.44/3.4
t = 1.6 hours
A general rule of thumb is that if numbers are involved it's quantitative and if characteristics are involved its qualitative, so in this case it'd be quantitative.
Answer:
Step-by-step explanation:
By similar triangles, you get
3/BD = BD/7
BD^2 = 21
BD = √21
Now you use Pythagoras to get x
7^2 + BD^2 = x^2
49 + 21 = x^2
60 = x^2
x = √60
7.746
