If i did the math correctly one number is 50
19 has two factors: 1, 19
21 has four factors: 1, 3, 7, 21
23 has two factors: 1, 23
And we need a number that has more than four factors and is greater than 25.
Factors of 50- 1, 2, 5, 10, 25, 50
50has six factors and is greater than 25.
Answer: (b+5)(b-5)
Step-by-step explanation:
both b^2 and 25 are square numbers, so square root both of them to give b and 5, then put into brackets with a + and -

Answer:≥2
Step-by-step explanation:
First, we need to translate the problem into algebraic expressions and equations:
[length][is][ten inches more than][twice the width]
⟹[][=][10+][2×]
⟹=10+2
==(10+2)()=22+10
[Area][is at least][28]
[][≥][28]
⟹≥28
Putting these together, we have a quadratic inequality:
22+10≥28
The most straightforward way [I know of] to solve this is to compare to zero, find the roots, and go from there:
22+10−28≥0
⟹2+5−14≥0
Finding the zeros using your favorite method — factoring, quadratic formula, etc. — yields zeros of ={−7,2} .
Since the width of the rectangle can’t be negative, our solution involves =2 . The graph of the quadratic function is concave up (due to the positive leading coefficient), meaning the function is non-negative for ≤−7 or ≥2 — giving us our solution, ≥2 !
