Expression 1:
b)
Gabrielle:
$125 * 2 = $250
300 - 125 = $175
c) $175 will be her new checking account balance.
Alicia:
d) Alicia used 1.5 gallons to travel a distance of 37.5 miles.
Kenneth:
Area of a triangle: A = 1/2*b*h (base = 6, height = 6)
A = 1/2 * 6 * 6
A = 1/2 * 36
A = 18 square inches
Since there are two triangles, it would be 18 * 2 = 36 square inches
Area of a rectangle: A = l*w (length = 9, width = 9)
A = 9 * 9
A = 81 square inches
Add the two areas together:
b) 36 + 81 = 117 square inches
Hope this helps!

Page 2 Answer: 175
Page 3 Answer: Alicia used 1.5 gallons to travel a distance of 37.5 miles.
Page 4 Answer: I think its 117 but I could be wrong...
Step-by-step explanation:
Page 1:
We just simplify by dividing and get 9/5
Page 2: Since they want to DOUBLE her amount in her savings, we double her current amount (125) and get 250 by adding.
Next, we subtract 125 from 300 in her checking and get 175.

We use the titles so solve the graph.
Answer:
C) p(x) has a zero between x=2 and x=4
Step-by-step explanation:
For a polynomial p(x), means that, when p(x) is divided by
, the remainder is
.
This is called the remainder theorem
Therefore ,
means that when p(x) is divided
and
is 1 and
respectively.
Also the Intermediate value theorem says that, if p(a) and p(b) have opposite signs then there is a certain on
where
i.e there is a zero between
and
Therefore the correct answer is C
Answer: Choice C.
============================================
Explanation:
The domain is the set of all allowed x inputs.
Here we see that x = -3 is the smallest x value possible as it is from the left-most point. The graph goes on forever to the right, so there is no largest x value. Effectively infinity is the largest x value even though infinity is not a number.
We can say the domain is which can be simplified to
or
In short: x can be -3 or larger.
Answer:
<h2>30% is enrolled out-of-district.</h2>Step-by-step explanation:
According to the word problem, the number is increased by 50%.
To increase a number by a percent, multiply the number and the percent.
We can do this by changing both percents to decimals.
To change a percent to a decimal, divide it by 100.
The number is INCREASED by 50% so 0.5 would become 1.5.
