Answer:
12 hours
Step-by-step explanation:
Let the number of hours be represented as h.
Sarah's surfboards charges a fee of $60 to rent a surfboard and then $10.50 per hour.
Mathematically ,
60 + 10.50h
Sally's surfboards does not charge a fee, but they cost $15.50 per hour
Mathematically,
15.50h
Equating both equations together
60 + 10.50h = 15.50 h
Collect like terms
60 = 15.50h - 10.50h
60 = 5h
h = 60/5
h = 12 hours
Therefore, the number of hours that the cost will be the same to rent a surfboard for each shop is 12 hours.
Given:
The dimensions of a rectangle are
and
.
To find:
The expression that represents the area of the rectangle in simplest terms.
Solution:
Area of a rectangle is:

The dimensions of a rectangle are
and
. So, the area of the given rectangle is:




Therefore, the correct option is F, i.e.,
.
The answer is B.
B is the answer because:
2(1)-8= -6
2(2)-8= -4
2(3)-8=-2
2(4)-8=0
Translate Circle A (x-3, y+5) and then dilate by a scale factor of 3/8 or 0.375
Given:
The polynomial is:

To find:
The degrees and determine whether it is a monomial, binomial, or trinomial.
Solution:
We have,

The highest power of the variable <em>x</em> in the given polynomial is 4. So, the degree of the polynomial is 4.
Monomial: Polynomial with one term.
Binomial: Polynomial with two terms.
Trinomial: Polynomial with three terms.
In the given polynomial, we have three terms
. So, the given polynomial is trinomial.
Therefore, the degree of the polynomial is 4 and it is a trinomial.
