Answer:

C) 90 in^2

Step-by-step explanation:

the other person above said exactly what i did too to get the answer above... and im doing the quiz too =w=

also if you need to know one answer that is obviously not the answer... the obvious wrong answer is D) 157,500 in^2... its way, WAY too big for it to be the answer

Hope this helps

Answer:

x=2 or x=8

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2x2−20x+50=18

Step 2: Subtract 18 from both sides.

2x2−20x+50−18=18−18

2x2−20x+32=0

Step 3: Factor left side of equation.

2(x−2)(x−8)=0

Step 4: Set factors equal to 0.

x−2=0 or x−8=0

x=2 or x=8

Answer:

1. x = 8

2. x = 2

Step-by-step explanation:

2 • (x - 5)2 -  18  = 0

2.1     Evaluate :  (x-5)2   =    x2-10x+25

3.1     Pull out like factors :

 2x2 - 20x + 32  =   2 • (x2 - 10x + 16)

3.2     Factoring  x2 - 10x + 16

The first term is,  x2  its coefficient is  1 .

The middle term is,  -10x  its coefficient is  -10 .

The last term, "the constant", is  +16

Step-1 : Multiply the coefficient of the first term by the constant   1 • 16 = 16

Step-2 : Find two factors of  16  whose sum equals the coefficient of the middle term, which is   -10 .

     -16    +    -1    =    -17

     -8    +    -2    =    -10    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -8  and  -2

                    x2 - 8x - 2x - 16

Step-4 : Add up the first 2 terms, pulling out like factors :

                   x • (x-8)

             Add up the last 2 terms, pulling out common factors :

                   2 • (x-8)

Step-5 : Add up the four terms of step 4 :

                   (x-2)  •  (x-8)

            Which is the desired factorization

2 • (x - 2) • (x - 8)  = 0

4.1    A product of several terms equals zero.

When a product of two or more terms equals zero, then at least one of the terms must be zero.

We shall now solve each term = 0 separately

In other words, we are going to solve as many equations as there are terms in the product

Any solution of term = 0 solves product = 0 as well.

Answer:

2 x c7 = 5

Step-by-step explanation:

Answer:

The lines will never intersect.

Step-by-step explanation:

The slope of the cups is the same, 1.5.  The y-intercept of the small cups is 6

The y-intercept of the big cups is 9.

This means that the lines will never intersect because they are parallel lines and have the same slope but different y-intercepts.

Answer:

6 pack = $7.70

18 pack=$23.10

Answer:

Step-by-step explanation:

d,

7.70 * 3 = 23.10

because 6 goes into 18 ,times.

or 7.70+7.70+7.70 = 23.10 so D

Answer:

(7,-5)

Step-by-step explanation:

you run 7 and go down 5

After solving the given expression, the equivalent expression will be -30 +40c - 10c.

If a mathematical operation includes at least two words that are connected by an operator and either comprise numbers, variables, or both, it is referred to as an expression.

The operations with reflection coefficients include adding, subtracting, multiplying, and dividing. A mathematical operation like reduction, addition, multiplication, or division is used to include terms in an expression.

As per the given information in the question,

-2(15 - 20d + 5c)

Now, multiply -2 by the values in the bracket,

Then, the equivalent expression will be,

-30 +40c - 10c

Answer:

40

Step-by-step explanation:

(11 + 4) / 3 * sqrt(64) =

= 15/3 * 8

= 5 * 8

= 40

Answer:

40 i think ?

Step-by-step explanation:

im not 100 percent sure this is correct but i just followed pemdas. i added 11 and 4 then divided that by 3, which was 5, then i figured out the square root of 64 which is 8 then multiplied 5 by 8 which is 40
