Answer:

Distribute:

=(−2)(4x)+(−2)(−4)+x

=−8x+8+x

Combine Like Terms:

=−8x+8+x

Answer:

x  

2

−4x+4=0

To solve the equation, factor x  

2

−4x+4 using formula x  

2

+(a+b)x+ab=(x+a)(x+b). To find a and b, set up a system to be solved.

a+b=−4

ab=4

Since ab is positive, a and b have the same sign. Since a+b is negative, a and b are both negative. List all such integer pairs that give product 4.

−1,−4

−2,−2

Calculate the sum for each pair.

−1−4=−5

−2−2=−4

The solution is the pair that gives sum −4.

a=−2

b=−2

Rewrite factored expression (x+a)(x+b) using the obtained values.

(x−2)(x−2)

Rewrite as a binomial square.

(x−2)  

2

To find equation solution, solve x−2=0.

x=2

Answer:

23 yards

Step-by-step explanation:

During a test flight, Jeri's rocket reached a height of 18 yards. This was 7 yards less than the height of Devon's rocket. Write and solve a subtraction equation to find the height of Devon's rocket.

Let us represent the height of Devon's rocket = x

18 yards = x - 7 yards

x = 18 yards + 7 yards

x = 23 yards

The height of Devon's rocket = 23 yards

12 divide by 2 you will get six or skip count by 2 and when you get to 12 count how many numbers you have then you will get the answer

Answer:

B

Step-by-step explanation:

First find the third angle straight linear make 180° so

180°-115°=65°

So 80°+65°+X=180°..triangle measure 180°

145°+X=180

X=180-145

X=35°

The second one. Again straight linear measure 180° so

180°-115°=65°

65°+85°+ Y=180°

150°+ Y=180°

X=180°-150°

Y=30°

Answer:

y= x - 1 3/4

Step-by-step explanation:

Answer:

1) 1924m²

2) a = (b x h) / 2

(5 x 12) = 60

60 / 2 = 30in²

30in² x 2 = 60in²

area of upper rectangle =

a = l x w

13 x 8 = 104in

area of backer rectangle =

a = l x w

12 x 8 = 96in

60in² + 104 + 96 = 260in²

(thats all i know sorry :/)

Answer:

480 cm 3

Step-by-step explanation:

Length x Weight x Height

Answer:

Refer to explanation..

Step-by-step explanation:

Since x represent same number when if it is used multiple times..

40 - 3 - 3 = 34 (Find out how many is 4 x)

4x = 34

X = 34 ÷ 4 = 8.5

I don't know what the question is finding for, if it's breadth then it's 8.5, if it is finding length..

Length = 8.5 + 3 = 11.5

Answer:

36 ounces

Step-by-step explanation:

If 1 cup equals 8 ounces, you would multiply 4 1/2 by 8. 8 x 4 is 32 (ounces), and half of 8 is 4, so 4 ounces. You would then add 32 and 4 together to get your answer. Hope this helps!!

Answer:

She needs 36 ounces.

Step-by-step explanation:

4 1/2=9/2

1/8=(9/2)/x

cross product

8(9/2)=1*x

72/2=x

x=36

Answer:

3.6 hours

Step-by-step explanation:

The computation of the number of hours will the battery last is given below:

Given that

The capacity of her battery is 2 by 5

And, it declines 1 by 9 for every hour

So,

[tex]= \frac{2}{5}\times \frac{9}{1}\\\\= \frac{18}{5}\\\\= 3\frac{3}{5}[/tex]

= 3.6 hours

Answer:

12y-30

Step-by-step explanation:

Answer:

Step-by-step explanation:

6(2y - 5):

6*2y - 6*5

12y - 30

Answer:

(4²πx2) + (8π x 4) = 201.061... OR 64π

Answer:

Step-by-step explanation:

5) r = 8/2 = 4 cm

Top and bottom = 2*πr²

                           = 2 * 3.14 * 4 * 4

                          = 100.48 cm²

Middle part = h * πd

                  = 4 * 3.14 * 8

                 = 75.36 cm²

Total = 100.38 + 75.36   = 175 .84 cm²

Answer:

-43/50

(decimal) = -0.86

Step-by-step explanation:

Find the LCD which is 50.

16/25 will be multiplied by 2 (because 25 x 2 = 50) so it will then equal 32/50

3/2 will be multiplied by 25 (2 x 25 = 50) = 75/50

subtract them which will give you -43/50

Answer: It’s C

Step-by-step explanation:

Answer:

mean: 65

median: 9

Step-by-step explanation:

You take all the numbers you have and add them up. Make it simple by adding smaller numbers together. Then once you have the total which is 65 you divide it by the total of numbers you have and then round because after dividing you get 8.125 and the safest way to round is to 9.

Answer:

10

Step-by-step explanation:

Answer:

Step-by-step explanation:

f(x) = x2  ...  when 'x' is equal to 5

So...

1.) Plug in 5 for the variable 'x'

f(5) = (5) * (2)

2.) Simplify both sides of the equation

5f = 10

3.) Divide both sides by 5

5f /5  =  10/5

f = 2

Answer:

Palanzio's Pizza: Y= .90x+6.80

Giudo's Pizza: Y= .65x+7.30

.90x + 6.80= .65x + 7.30

.25x + 6.80= 7.30

.25x = .50

x = 2
