Answer:
I'm not completely sure but if they want exponents for 6 * 6 * 6 then it should be 
Step-by-step explanation:
1.
The edge lengths of a triangle are inversely proportional to 2,3 and 4.
The actual proportions of the lengths are then
12(1/2:1/3:1/4)=6:4:3
The longest side
= 39* (6/(6+4+3)
= 39*6/13
=18
2. 63 breads : 35 kg flour
is the same as
54 breads : x kg flour
Cross multiply and get
x=54*35/63=30
30 kg of flour are needed to make 54 breads.
The answer is b. I hope this helps and good luck
Answer:
7n-4;696
Step-by-step explanation:
I look at it as having ordered pairs (1,3), (2,10), (3,17), etc
looks like the y's increase by 7 for every increase of 1 in the x's, so the slope = 7
thus y = 7x + b
plug in (1,3) ----> 3 = 7 + b or b = -4
y = 7x - 4
in sequence terms: termn = 7n - 4
term100 = 7(100)-4 = 696
