The expression for the number of boy cousins will be f – 4.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

Marcella has 4 fewer male cousins than female cousins.

Let f represent the number of female cousins.

Then the expression for the number of boy cousins will be

⇒ f – 4

Answer:

He gave you 48 cards.

Step-by-step explanation:

150 * 32% (which is also 0.32) is equal to 48.

Divide the percentage by 100.

32 / 100 = 0.32.

You then multiply 0.32 by 150 to get the part.

0.32 x 150 = 48.

32% of 150 is 48.

Your answer is 48 cards.

Let's look at the factors of 28.

1,28

2,14

4,7

We see that 4 and 7 add to make 11, but not -11. Well, we can just make both of them negative and then it will be -11 and their product will still be 28. Our numbers are -4 and -7.

Have a wonderful day! :D

Answer:

the answer is ( p+2 ) (p+16)

Answer:

Step-by-step explanation:

5x - 6y = 27 .......... Equation 1

7x + 6y = 9 ………… Equation 2

To solve using elimination add the second equation to the first one to eliminate y

That's

5x - 6y + 7x + 6y = 27 + 9

12x + 6y - 6y = 36

12x = 36

Divide both sides by 12

x = 3

Substitute it into any of the equations

Using equation 2

That's

7(3) + 6y = 9

21 + 6y = 9

6y = - 12

Divide both sides by 6

y = - 2

The solutions are

x = 3

y = - 2

Answer:

14 books

Step-by-step explanation:

Let b = number of books at the beginning

She sold 1/2 of the books

b - 1/2 b

This is how many she had left

Then she bought 7

b - 1/2 b + 7

this equals 14

b - 1/2 b + 7 = 14

Combine like terms

1/2 b + 7 = 14

Subtract 7 from each side

1/2 b = 14-7

1/2 b = 7

Multiply each side by 2

1/2 b * 2 = 7*2

b = 14

She started with 14 books

Answer:

[tex]\huge\boxed{A=(9x^2-48x+64)ft^2}[/tex]

Step-by-step explanation:

The formula of an area of a square:

[tex]A=s^2[/tex]

[tex]s[/tex] - side of a square

We have [tex]s=(3x-8)ft[/tex]

Substitute:

[tex]A=(3x-8)^2[/tex]

METHOD 1:

Use  [tex](a-b)^2=a^2-2ab+b^2[/tex]

[tex]A=(3x)^2-2(3x)(8)+8^2=9x^2-48x+64[/tex]

METHOD 2:

Use FOIL: [tex](a+b)(c+d)=ac+ad+bc+bd[/tex]

[tex]A=(3x-8)(3x-8)=(3x)(3x)+(3x)(-8)+(-8)(3x)+(-8)(-8)\\\\=9x^2-24x-24x+64=9x^2-48x+64[/tex]

Answer:

9x^2-48x+64 ft^2

Step-by-step explanation:

(3x − 8) (3x − 8)

Multiply 3x by (3x − 8)

3x(3x − 8)

9x^2-24x

Multiply - 8 by (3x − 8)

- 8(3x − 8)=-24x+64

Combine 9x^2-24x and -24x+64

9x^2-48x+64 ft^2

Answer:

A. x-4y=8

Step-by-step explanation:

Slope = [tex]\frac{1}{4}[/tex]

y-intercept = -2

In y=mx+b

m = slope

b = y-intercept

Just replace m with 1/4 and b  with -2

[tex]y = \frac{1}{4} x -2\\[/tex]

Multiply through by 4 and re-arrange

[tex]4(y=\frac{1}{4} x -2)\\\\4y =x -8\\0 =-4y +x-8\\8 =-4y+x\\\\x -4y =8[/tex]

I believe the standard form is: ax2+bc+c=0

Vertex form is:f(x)=a(x-h)2+k

Factored form is: y=1/2(x-6)(x+2)

The ax2= ax squared and the (x-h)2= (x-h) squared

Answer:

because entries in the table are frequency counts, the table is a frequency table. Entries in the total row and total column are called marginal frequencies or the marginal distribution

We can use the pythagorean theorem to solve this

The pythagorean theorem = a^2 + b^2 = c^2, while

a = one leg

b = the second leg

c = the hypotenuse

In this problem,

a = 3

b = 15

c = ?

Let's plug our values into the pythagorean theorem

(3)^2 + (15)^2 = c^2

9 + 225 = c^2

Add together the left side

234 = c^2

Take the sqrt of both sides

sqrt(234) = c

The length of BC = sqrt(234)

[tex] \boxed{ \sf{length \: of \: a \: rectangle = 60 \: yd}}[/tex]

[tex] \boxed{ \sf{width \: of \: a \: rectangle = 10 \: yd}}[/tex]

Step-by-step explanation:

Let the width of a rectangle be 'w'

Length of a rectangle ( l ) = 6w

Perimeter of a rectangle ( P ) = 140 yd

Finding the width of a rectangle

[tex] \boxed{ \sf{perimeter \: of \: rectangle= 2(length + breadth)}}[/tex]

[tex] \dashrightarrow{ \sf{140 = 2(6w + w)}}[/tex]

[tex] \dashrightarrow{ \sf{140 = 2 \times 7w}}[/tex]

[tex] \dashrightarrow{ \sf{140 = 14w}}[/tex]

[tex] \dashrightarrow{ \sf{14w = 140}}[/tex]

[tex] \dashrightarrow{ \sf{ \frac{14w}{14} = \frac{140}{14}}} [/tex]

[tex] \dashrightarrow{ \sf{w = 10}}[/tex]

Width of a rectangle = 10 yd

Now, replacing / substituting the value of w in 6w in order to find the length of a rectangle

[tex] \dashrightarrow{ \sf{length = 6 \times x = 6 \times 10 = 60 \: yd}}[/tex]

Length of a rectangle = 60 yd

Answer:

d.imaginary and unequal

Step-by-step explanation:

In an effort to address this problem, mathematicians "created" a new number, i, which was referred to as an "imaginary number", since it was not in the set of "Real Numbers". This new number was viewed with much skepticism. The imaginary number first appeared in print in the year 1545

The imaginary number "i" is the square root of negative one.

neg i

An imaginary number possesses the unique property that when squared, the result is negative.
