Answer: (3a + 1) (a + 3)
Step-by-step explanation:
<u>Concept:</u>
Here, we need to know the idea of factorization.
It is like "splitting" an expression into a multiplication of simpler expressions. Factoring is also the opposite of Expanding.
<u>Solve:</u>
Given = 3a² + 10a + 3
<em>STEP ONE: separate 3a² into two terms</em>
3a
a
<em>STEP TWO: separate 3 into two terms</em>
3
1
<em>STEP THREE: match the four terms in ways that when doing cross-multiplication, the result will give us 10a.</em>
3a 1
a 3
When cross multiply, 3a × 3 + 1 × a = 10a
<em>STEP FOUR: combine the expression horizontally to get the final factorized expression.</em>
3a ⇒ 1
a ⇒ 3
(3a + 1) (a + 3)
Hope this helps!! :)

Step-by-step explanation:
Answer:
is the inequality that reflect the relationship.
Step-by-step explanation:
Given:
Charge for rental = $100
Additional charge = $ 35
Minimum amount that can be spent = $280
To Find:
equations or inequalities that reflect the relationship = ?
Solution:
Let x be the minimum number of hours
then the charge will be
100 + (number of hours)(additional cost per hour)
That is
100 + 35x
Now the minimum charge amount is $280 So, The charge can be 280 or more than 280
