If F(x) = x² + 5x and G(x) = 2x + 1, find F(5) + G(6). 48 63 107

Answers

Answer:

63

Step-by-step explanation:

F(x) = x² + 5x

F(5) = (5)² + 5(5) = 25 + 25 = 50

G(x) = 2x + 1

G(6) = 2(6) + 1 = 12 + 1 = 13

F(5) + G(6) = 50 + 13 = 63

Which shape has a greater perimeter?

Answers

Answer: Shape B, which is the thin and long rectangle.

Step-by-step explanation:

Shape A:

4 + 4 + 8 + 8

4+4 = 8

8 + 8 = 16

16 + 8 = 24

Shape A has a perimeter of 24.

Shape B:

2 + 2 + 11 + 11

2 + 2 = 4

11 + 11 = 22

22 + 4 = 26

Shape B has a perimeter of 26.

Erik transformed the equation y = 2(x − 2)^2 + 5 from vertex form to standard form. His steps are shown below. Is Erik's work correct? If not, identify and correct his error.
y = 2(x − 2)^2 + 5
y = 2(x^2 − 4x + 4) + 5
y = 2x^2 − 8x + 8 + 5
y = 2x^2 − 8x + 13
A. No. The error is in the second line: the expanded form of (x − 2)^2 is x^2 − 4.
B. No. The error is in the third line: the product of 2 and x^2 − 4x + 4 is 2x^2 − 4x + 4.
C. No. The error is in the fourth line: the sum of 8 and 5 is 12.
D. Yes. Erik is correct in his transformation from vertex form to standard form.

Answers

Answer:

1/16

Step-by-step explanation:

The equation of a direct proportion is

y = kx

Let amount of fertilizer = y and amount of peat moss = x

We have x = 12 when y = 3/4

3/4 = k * 12

k = (3/4)/12 = 3/4 * 1/12 = 3/48 = 1/16

y = 1/16 x

The constant of proportionality is 1/16.

What is the surface area of the solid that this net can form?
A. 106 square centimeters
B. 150 square centimeters
C. 210 square centimeters
D. 270 square centimeters

Answers

C. 210 sq cm.

13 + 12 + 5 = 30 (length)
30 • 5 = 150 sq cm (the total area of the long rectangles across)

12 • 5 = 60 sq cm
(no need to divide by 2 even if they are triangles because there are two on either side so they would cancel out)

150 + 60 = 210 sq cm.

4/9 kilogram of baking soda costs $2. How much does 1 kilogram of baking soda cost?

please drop an explanation, and equation thanks!

Answers

Ok so we want to cross multiply.
To do this you know 4/9=2$ so now you want to know 1=x$
When you do this you get $5

Answer:

1 kg of baking soda costs $4.50.

Step-by-step explanation:

Write and solve an equation of ratios, as follows:

 4/9 kg            $2

------------- = --------------

    1 kg               x

Multiplying both numerators by 9, we get:

  4 kg          $18

------------ = ---------

   1 kg             x

Cross-multiplying, we get 4x kg = $18-kg.  Solving for x, we get:

        $18-kg

x = -------------- = $4.50

         4kg

1 kg of baking soda costs $4.50.

Which expression is equivalent to 3(4m - 2) - 2(m + 5)

A. 10m - 16

B. 14m + 4

C. -16m + 10

D. 12m - 6

Answers

Answer:

A. 10m - 16

Step-by-step explanation:

First, distribute 3 to all terms within the corresponding parenthesis, and -2 likewise:

3(4m - 2) =

3 * 4m = 12m

3 * -2 = -6

3(4m - 2) = 12m - 6

-2(m + 5) =

-2 * m = -2m

-2 * 5 = -10

-2(m + 5) = -2m -10

Combine like terms:

12m - 6  -2m - 10

12m - 2m - 6 - 10

(12m - 2m) + (-6 - 10)

10m - 16

A. 10m - 16 is your answer.

~

Answer:

10 m - 16 (Answer A)

Step-by-step explanation:

We use distributive property to eliminate parenthesis:

12 m - 6 - 2 m -10

and now combine like terms:

[12 m - 2 m] - 6 - 10

10 m - 16

Therefore, answer option A.  is the correct one
