Answer:

I think It's a triangle too

Step-by-step explanation:

Answer:

n must be 27

Step-by-step explanation:

Let this number be x.  Then -6(n - 12) = -90.

Dividing both sides by -6 yields n - 12 = 15.

Add 12 to both sides.

Then n must be 27.

Check:  subtract 12 from 27; this yields 15.  Now multiply this result by -6.  The result is -90, which was expected.

Rectangular prism is also called cuboid.

Formula :

[tex]\bigstar \: \boxed{\sf {Volume_{(Cuboid)} = \ell \times b \times h}} \\ [/tex]

[tex] \longmapsto [/tex] Volume = (3 × 6 × 2) feet[tex]\sf ^3 [/tex]

[tex] \longmapsto [/tex] Volume = (18 × 2) feet[tex]\sf ^3 [/tex]

[tex] \longmapsto [/tex] Volume = 36 feet[tex]\sf ^3 [/tex]

Answer:

x=4 positive solution

Step-by-step explanation:

hello :

-x²-x+20 = 0

-(x²+x-20) = 0

means : x²+x-20=0

(x+5)(x-4) =0

x+5 =0 or x-4 =0

x = - 5 refused  x=4 positive solution

Answer:

A.P+C=O

A(2).P+C=$7.00

B.A (1) that expression doesnt give the amount for both sets of cookiea all together its just shown as a letter.A(2) its shows p+c as $7.00 showing thats how much for both sets of cookies instead of having a letter to represent the amount payed.

Step-by-step explanation:

Answer:6

Step-by-step explanation:

Answer:

x = 6

y = -1

Step-by-step explanation:

x = - 6y ----------------------(I)

4x + 10y = 14 ------------------(II)

Substitute x = -6y in equation (II)

4*(-6y) + 10y = 14

-24y + 10y = 14  {Combine like terms}

           -14y = 14   {Divide both sides by 1-4}

               y = 14/-14

y = -1

Now, substitute y = -1 in equation  (I)

x = - 6*(-1)

x = 6

Answer:

y = 2 (x + seven-halves) squared minus one-fourth [y =  [tex](x + \frac{7}{2} )^{2} - \frac{1}{4}[/tex] ]

Step-by-step explanation:

We know that,

vertex form is y = a(x-h)² + k

vertex is (h, k)

Now,

Given that the equation is -

y = (x+3)² + (x+4)²

 = x² + 3² + 2×3×x + x² + 4² + 2×4×x

= x² + 9 + 6x + x² + 16 + 8x

= 2x² + 14x + 25

= [tex]x^{2} + 7x + \frac{25}{2}[/tex]

= [tex]x^{2} + 7x + \frac{25}{2} + \frac{49}{4} - \frac{49}{4}[/tex]

= [tex](x + \frac{7}{2} )^{2} + \frac{25}{2} - \frac{49}{4}[/tex]

= [tex](x + \frac{7}{2} )^{2} - \frac{1}{4}[/tex]

∴ we get

The vertex form is -

y = [tex](x + \frac{7}{2} )^{2} - \frac{1}{4}[/tex]

So,

The correct option is - y = 2 (x + seven-halves) squared minus one-fourth (y =  [tex](x + \frac{7}{2} )^{2} - \frac{1}{4}[/tex] )

Step-by-step explanation:

Answer:

Y= 4   and    X=2

Step-by-step explanation:

When you are trying to find the X or Y value for an equation, set the opposite value to zero. That means that if you are trying to find Y in 6x+3y=12, you would make the X zero. Since six is being multiplied by X and X now equals zero, your equation for finding the Y value is now 3y=12. Divide them both by three and you get Y=4. In order to find your X value you would do the same thing. Since you are trying to find X, set the Y value to zero. That makes your equation for finding the X value 6x=12. That is because, again, you set Y to zero, and three times zero is zero. 6x=12 equals X=2 because you divide both sides by 6.

Step-by-step explanation:

Answer:

One acute angle is 31 degrees and the other  acute angle is ( 31+28=)  59 degrees.

Step-by-step explanation:

In the right angled triangle one angle is always equal to 90 degrees.

Suppose <a= 90 degrees

     < b= x degrees

    < c= x+28 degrees

The sum of all the angles of the triangle are always equal to 180 degrees

therefore

<a+ <b+<c= 90 + x+ x+28 = 180

or

2x= 180- 28- 90

2x=62

x= 31 degrees

One acute angle is 31 degrees and the other  acute angle is ( 31+28=)  59 degrees.

An acute angle is an angle which has less than 90 degrees in measurement .

Hence both angles of the right angle triangle are acute angles , 31 and 59 degrees.

3(x-6) is the correct answer to your question :)

Answer:

3x - 6 or 3x -6

Step-by-step explanation:

it is a distrubuve property so u multiply the numbers in the bracket by 3.so 3 time x is 3x.and the other one if it is -2 it is -6 but if its just 2 it is 6.

Hope it helped.

Answer:

$835 (Answer c)

Step-by-step explanation:

Write out the Cost function:  C(n) = $65 + ($11/person)n

Then the total cost for 70 people would be C(70) = $65 + ($11/person)(70 people)

C(70) = $65 + $770 = $835 (Answer c)

Answer:

$9.75

Step-by-step explanation:

Here are two ways of solving this:

Method 1) calculate 35% of original price and subtract from original price

original price: $15

discount rate: 35%

amount of discount: 35% of $15 = 0.35 * $15 = $5.25

final price = original price - amount of discount = $15 - $5.25 = $9.75

Method 2) calculate the percent the discount amount is, and calculate the amount

original price = $15 = 100% of original price

discount rate = 35%

Since the discount rate is 35%, then 100% - 35% = 65%, meaning the sale price is 65% of the original price.

final price = 65% of $15 = 0.65 * $15 = $9.75
