I'm assuming the question is asking for you to factor the expressions.
b.
(x-3)(x+2)
-3+2=-1
-3*2=-6
d.
(x-6)(x-7)
-6-7=-13
-6*-7=42
Answer:
120 degrees
Step-by-step explanation:
Angle 1 is congruent to angle 5 by the corresponding angles theorem.
Answer:
Here we have two inequalities.
P is price of the gallon,we have that:
$2.40 ≤ P ≤ $2.65
C is the amount of gallons that Ricardo buys each week.
8,5 ≤ C ≤ 11
Now, with this you can find the maximum and minimum amount that he can spend on a week.
The minimum is when he buys only 8.5 gallons and the price per gallon is $2.40
Cost = 8.5*$2.40 = $20.4
The maximum cost is when he buys 11 gallons, and the price of the gallon is $2.65
Cost = 11*$2.65 = $29.15
So the amount that he spends per week in gas, S, is:
$20.4 ≤ S ≤ $29.15
