Does anybody have an answer for this question?

There are eight people competing in the track meet this weekend. They are competing for 1st, 2nd, and 3rd place ribbons. How man

malfutka [58]

Answer:

Option C

Step-by-step explanation:

Assuming P represents the number of outcomes, n the number of competitors and r the number of places to be awarded....

$P = n! / ( n - r )!\\P = 8! / ( 8 - 3 )!\\P = 8! / 5!\\\\Algebra, P = 336 \\Solution = Option C$

There are 336 different possible ways for the winners to be chosen.

Finger [1]

Answer: C) 25

Step-by-step explanation:

x²+10x+ __=16+ __

Only the square of 5, 5², which is 25, can make the two factors plus equal to 10x, so we need to add 25.

Alyze the following special produ

Eddi Din [679]

Answer:

1) Solving the term $(3x + 5)(2x - 3)$ using F.O.I.L we get $\mathbf{6x^2+x-15}$

2) solving the term $(x + 2)(x - 13)$ using F.O.I.L we get $\mathbf{x^2-11x-26}$

3) Solving $(x+5)^2$ using square of binomial we get $\mathbf{x^2+10x+25}$

4) Solving $(x+5)^2$ using square of binomial we get $\mathbf{x^2-6x+9}$

Step-by-step explanation:

1) (3x + 5)(2x - 3). Solve using the F.O.I.L.

F.O.I.L stands for First, Outer Inner Last

We have $(3x + 5)(2x - 3)$

First: 3x(2x)

Outer: 3x(-3)

Inner: 5(2x)

Last: 5(-3)

Solving we get:

$(3x + 5)(2x - 3)\\=3x(2x)+3x(-3)+5(2x)+5(-3)\\=6x^2-9x+10x-15\\=6x^2+x-15$

So, solving the term $(3x + 5)(2x - 3)$ using F.O.I.L we get $\mathbf{6x^2+x-15}$

2) (x + 2)(x – 13). Solve using the F.O.I.L.

F.O.I.L stands for First, Outer Inner Last

We have $(x + 2)(x -13)$

First: x(x)

Outer: x(-13)

Inner: 2(x)

Last: 2(-13)

Solving we get:

$(x + 2)(x - 13)\\=x(x)+x(-13)+2(x)+2(-13)\\=x^2-13x+2x-26\\=x^2-11x-26$

So, solving the term $(x + 2)(x - 13)$ using F.O.I.L we get $\mathbf{x^2-11x-26}$

3) (x + 5)^2. Solve using the square of Binomial.

The square of binomial is: $(a+b)^2=a^2+2ab+b^2$

Solving:

$(x+5)^2\\=(x)^2+2(x)(5)+(5)^2\\=x^2+10x+25$

So, solving $(x+5)^2$ using square of binomial we get $\mathbf{x^2+10x+25}$

4) (x -3)^2. Solve using the square of Binomial.

The square of binomial used is: $(a-b)^2=a^2-2ab+b^2$

Solving:

$(x-3)^2\\=(x)^2-2(x)(3)+(3)^2\\=x^2-6x+9$

So, solving $(x+5)^2$ using square of binomial we get $\mathbf{x^2-6x+9}$

Use the distributive property and the greatest common factor to rewrite the sum 25 + 60.

Kitty [74]

The factors of 25 and 60 would be 5. 25 divided by 5 is 5 and 60 divided by 5 is 12.

So here is what the distributive property looks like.

a(b+c)=a*b+a*c but we are going to rewrite a*b and a*c as 5*5 and 12* 5

a(b+c)=5*5+12*5

So i'd say its 5*5+5*12 i hope this helps
