Answer:
(b+1)(b²+1)
Step-by-step explanation:
If you do 39.80/ 3 it would give you 13.2667miles and since the tip was not added that’s when you don’t do anything with that number and 3 because every mile you pay 3$
About 3 in a half years I think

For proportions and to find x we have to cross multiply
8 × (x) = 3 × 2.4
8x = 7.2
Divide by 8 to isolate x

8 and 8 cancels out
x = 0.9
<span>The sum of two numbers is 48.
a + b = 48
;
If one third of one number is 5 greater than one sixth of another number,
a = b + 5
multiply both sides by 6, cancel the fractions
2a = b + 30
2a - b = 30
</span><span>use elimination to solve this
a + b = 48
2a - b =30
-------------Addition eliminates b, find a
3a = 78
a =
a = 26
then
26 + b = 48
b = 48 - 26
b = 22</span>
