25
Step-by-step explanation:
Answer:
E. x² + 11x - 42 = 0
Step-by-step explanation:
let the square sides be x
A = bh = (x + 3 + 3)(x + 2 + 3) = 72
(x + 6)(x + 5) = 72
x² + 11x + 30 = 72
x² + 11x - 42 = 0
Answer: Choice D
b greater-than 3 and StartFraction 2 over 15 EndFraction
In other words,
b > 3 & 2/15
or

========================================================
Explanation:
Let's convert the mixed number 2 & 3/5 into an improper fraction.
We'll use the rule
a & b/c = (a*c + b)/c
In this case, a = 2, b = 3, c = 5
So,
a & b/c = (a*c + b)/c
2 & 3/5 = (2*5 + 3)/5
2 & 3/5 = (10 + 3)/5
2 & 3/5 = 13/5
The inequality
is the same as 
---------------------
Let's multiply both sides by 15 to clear out the fractions

---------------------
Now isolate the variable b

Side note: Another way to go from 47/15 to 3 & 2/15 is to notice how
47/15 = 3 remainder 2
The 3 is the whole part while 2 helps form the fractional part. The denominator stays at 15 the whole time.
