Hey there!

So, when finding area, we need to remember that the key point if this is to (multiply).

We would need to make sure that we do not get confused with (perimeter) and area.

We are going to multiple, sense the question stated "<span>What is the area of the flower bed?".

To begin, what are the </span>(formula) that we would use?

We will use . . .           \left[\begin{array}{ccc}\boxed{A= \frac{ h_{b}b }{2}}  \end{array}\right]

By using this, we would plug in the numbers to get your area.

\left[\begin{array}{ccc}\boxed{\boxed{13*5=65/2=32.5}}\end{array}\right]

Your correct answer would be (option B)

\boxed{32.5} \ square \ feet

I hope this helps you!

Are the expressions x + x + 1 + x + 2 + x + 1 + x and 5x + 4 equivalent? Why or why not?
egoroff_w [7]

Answer:

yes

they are equivalent because lets say the X = 3 then you would have to answer

3 + 3 + 1 + 3 + 2 + 3 + 1 + 3

and that would = 19

and then on the other equation

5 x 3 + 4 = 19

So the both equal the same.

Which of the following sets are closed under multiplication? Select all that apply.
ivolga24 [154]

Answer:

Integers, whole numbers and polynomials are sets of closed under multiplication.

Only Irrational numbers are not the sets of closed under multiplication.                  

Step-by-step explanation:

To find : Which of the following sets are closed under multiplication?

1. Integers  

Yes, integers is a sets of closed under multiplication as if you multiply an integer by an integer, you will always get another  integer.

Example - 3\times 3=9 is an integer

2. Irrational numbers


No, irrationals are not closed under multiplication.

Example - \sqrt{3} \times \sqrt{3} =3 is a rational number

3. Whole numbers


Yes, whole numbers is a sets of closed under multiplication as if you multiply a whole number by a whole number, you will always get another  whole number.

Example - 5\times 5=25 is a whole number

4. Polynomials

Yes, polynomial is sets of closed under multiplication as if you multiply the variables' exponents are added, and the exponents in polynomials are whole numbers so the new exponents will be whole numbers.

Example - (x + 1)(x^2 + 4x + 3) = x^3 + 5x^2 + 7x + 3 is a polynomial.

A farmer raises cows and chickens. There are a total of 114 legs and 42 animals 4y = cow legs and 2x = chicken legs. how many co
Fofino [41]
X+y=42, 4y+2x=114

y=42-x

4(42-x)+2x=114
168-4x+2x=114
168-2x=114
168-114=2x
54=2x
54/2=x
27=x

plug 27 into y=42-x

y=42-27
y=15
