Answer:
<h3>D. P = 15 and Q = 15</h3>
Step-by-step explanation:
Put the values of P and Q to the equation Px - 45 = Qx + 75:
15x - 45 = 15x + 75 <em>subtract 15x from both sides</em>
-45 = 75 FALSE
In other cases, we get some value x.
Example:
A. P = -45 and Q = -75
-45x - 45 = -75x + 75 <em>add 45 to both sides</em>
-45x = -75x + 120 <em>add 75x to both sides</em>
25x = 120 <em>divide both sides by 25</em>
x = 4.8
Answer:
f(5)=14
Step-by-step explanation:
f(5)=2(5)+4
f(5)=10+4
f(5)=14
Area of square=side^2
area=112
112=side^2
sqrt both sides
√112=side
4√7=side
4√7 ft is each side
