Could you show where is Point H?
The factored form of the expression is given as (x-6)(x-3)
<h3>Factoring quadratic equation</h3>
Quadratic equation are equation that has a leading degree of w.
Given the given quadratic equations
x^2 – 9x + 18
Factorize to have;
x^2 - 3x - 6x + 18
x(x-3) -6(x -3)
(x-6)(x-3)
Hence the factored form of the expression is given as (x-6)(x-3)

To answer this question, it is easier to make a list of the repair cost based on the hour of labor. The first hour is $45 then after that $25/hour. Then the list would look like
0-1 h= $45
1-2h= $70 ($45 +1*$25)
2-3h= $95 ($45 +2*$25)
3-4h= $120 ($45 +3*$25)
Looking at the list, the answer should be
<span>B. C(t) = 95 for 2 < x ≤ 3</span>
If we observe closely the given, we can note that the
terms given are perfect cubes. That is,
<span> x^3 is
cube of x and</span>
<span> 343 is
cube of 7</span>
Hence, the expression is the sum of two cubes. For the
sum of cubes, we follow the following rule for the factoring:
<span> a^3 + b^3 = (a +
b)(a^2 – ab + b^2)</span>
Applying the rule to the given, the factors would be:
<span> X^3 + 373 = (x +
7)(x^2 – 7x + 49)</span>
A. 13
Explanation= 6 (sons) +6 (daughters) +1 (mother) = 13.
