Answer:
(x + 7)(x^2 + 3)
Step-by-step explanation:
The two constant terms in the binomials must have a positive product, so both will have the same sign. This eliminates the last two choices.
The coefficient of x^2 is +7, which eliminates the first choice.
The factorization is shown by the second choice:
(x + 7)(x^2 + 3)

Answer
QR = 28 inches or 44 inches
explain.
In right triangle QNP, the length of QN is given by the Pythagorean theorem as ...
QP² = QN² +PN²
QN = √(QP² -PN²) = √(1521 -225) = √1296 = 36
In right triangle RNP, the length of RN is similarly found:
RN = √(RP² -PN²) = √(289 -225) = √64 = 8
So, we have N on line QR with QN = 36 and RN = 8.
If N is between Q and R, then ...
QR = QN +NR = 36 +8 = 44
If R is between Q and N, then ...
QR = QN -NR = 36 -8 = 28
The possible lengths of QR are 28 in and 44 in

Step-by-step explanation:
Given data
We are told that Mary earns $7.25 an hour
The function for her salary is s = 7.25h
<em>s is a function of h because h is the time, and s a dependent variable on the time, the longer she works the more money she makes</em>
