1/2 (4r+6) what dose (4r+6) mean

1 answer:

Alisiya [41]3 years ago

5 0

Answer: 5

This is because (4r + 6) means you take r and multiply that number by 4.

Because there is no number, r would equal one in this case.

4 • 1 is 4

4 + 6 is 10

This would give us 1/2(10)

Half of 10 is 5.

Therefore, the answer is 5.

Solve for p. 20p + -5p – -17 = -13

STatiana [176]

$20p + -5p - -17 = -13$

$20p + -5p - -17 = -13:p$ $|Solve \ for \ p|$

$20p-5p+17=-13$

$
15p+17=-13
 
$

$
15p=-13-17
 
$ $|Subtract \ 17 \ from \ both \ sides|$

$
15p=-30
 
$

$
15p/15=-30/15
 
$ $|Divide \ both \ sides \ by \ 15|$

$
p=-2

(3x-8)° (4x-23)° fine the x

Veronika [31]

You cannot find x.

Because both phrases are to the power of 0, we know that it is essentially 1*1

So:

(3x - 8)^0 (4x - 23)^0 = 1

Rewrite x2 − 6x + 7 = 0 in the form (x − a)2 = b, where a and b are integers, to determine the a and b values.

Setler79 [48]

Answer:

Therefore values of a and b are

$a=3\ and\ b = 2$

Step-by-step explanation:

Rewrite $x^{2}-6x+7=0$ in the form

$(x-a)^{2}=b$

where a and b are integers,

To Find:

a = ?

b = ?

Solution:

$x^{2}-6x+7=0$ ..............Given

Which can be written as

$x^{2}-6x=-7$

$(\frac{1}{2} coefficient\ of\ x)^{2}=(\frac{1}{2}\times -6)^{2}=9$

Adding half coefficient of X square on both the side we get

$x^{2}-6x+9=-7+9=2$ ...................( 1 )

By identity we have (A - B)² =A² - 2AB + B²

Therefore,

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

Substituting in equation 1 we get

$(x-3)^{2}=2$

Which is in the form of

$(x-a)^{2}=b$

On comparing we get

a = 3 and b = 2

Therefore values of a and b are

$a=3\ and\ b = 2$
