H + m = 480
h = 2m
2m + m = 480
3m = 480
m = 480/3
m = 160 <=== there were 160 math books
h = 2m
h = 2(160)
h = 320 <=== there were 320 history books
The algebraic factor is the multiplication term that can be common to the whole equation thus the factorization form of 3n²+5n+2=0 will be (n + 1)(3n + 2) = 0.
<h3>What is an algebraic factor?</h3>
An algebraic factor is the multiplication of two algebraic terms.
The root of the quadratic equation formed by the algebraic factor is always real.
That term could be in form of summation multiplication or in subtraction.
As per the given quadratic equation,
3n²+5n+2=0
Let's 5n = 2n + 3n
3n²+ (3n + 2n) + 2 = 0
3n² + 3n + 2n + 2 = 0
(3n² + 3n) + (2n + 2) = 0
3n(n + 1) + 2(n + 1) = 0
(n + 1 )(3n + 2) = 0
Hence "The algebraic factor is the multiplication term that can be common to the whole equation thus the factorization form of 3n²+5n+2=0 will be (n + 1)(3n + 2) = 0".

Answer:
40°
Step-by-step explanation:
<CAB=70°
<ABC=70°
<ACB+ <CAB+ <ABC=180(sum of angles in a triangle)
<ACB +70+70=180
<ACB+140=180
<ACB=180-140
<ACB=40°
Answer:
5, 9
Step-by-step explanation:
To obtain the next term in a sequence add the common difference d to the previous term.
d = a₂ - a₁ = - 3 - (- 7) = - 3 + 7 = 4
Thus
a₄ = a₃ + 4 = 1 + 4 = 5
a₅ = a₄ + 4 = 5 + 4 = 9
