.divide the problem.

quester [9]

Answer:

$x - 2x - 15 \: divided \: by \: x - 3$

according to the above x²-2x-15 divided by the number below x-3 first I cancel out the x
$x - 2x - 15 \: divided \: by \: - 3$
the we solve the next x-5 divided by x²-9 then as usual rule out the x
$- 5 \: divided \: by \: x - 9$
now we only have x-2x-15 divided by-3 divided by-5÷x-9 now our next step is to again single the equations out
$x - 2x - 15 \: divided \: by \: - 3 \: lets \: rue \\s \: rule \: out \: - 3 \: and \: 15 \: giving \: us \: x - 2x - 5$
now the next -5 divided by x-9 here there's nothing to rule out therefore the sign "÷" is changed to "×" cancel out the -5 and therefore we have
$x - 2x = x - 9 \: as \: final \: answer$

Answer pls and ill give you brainlliest

posledela

you have 4 fields where it can land, so the probability has a denominator 4.

2 of those fields have a even number so the numerator is 2.

-> probability is 2/4= 1/2

What value for C will make the expression a perfect square trinomial x2-7x+c

Tom [10]

Answer:

The value of c is 12.25

Step-by-step explanation:

we know that

A perfect square trinomial is of the form

$(x-a)^{2}=x^{2}-2ax+a^{2}$

In this problem we have

$x^{2}-7x+c$

so

equate the equations

$x^{2}-7x+c=x^{2}-2ax+a^{2}$

we have

the following equations

$-7x=-2ax$ -----> equation A

and

$c=a^{2}$ -----> equation B

<u>Solve the equation A</u>

$-7x=-2ax$

$7=2a$

$a=3.5$

<u>Solve the equation B</u>

$c=a^{2}$

$c=3.5^{2}=12.25$

therefore

$(x-3.5)^{2}=x^{2}-7x+12.25$

The value of c is 12.25

What is the solution to the equation PLS

brilliants [131]

Answer:

x=2.5

Step-by-step explanation:

the first thing you want to do is simplify like terms.

you could say this is as 4(x+7)=38

this can easily be solved algebraically.

first use distributive property on the four

this leaves you with 4x+28=38

next, subtract 28 from both sides

4x=10

now divide everything by four and you get x=2.5
