The expressions are equivalent to the perimeter of the shape is c. 4x + 4

The perimeter of a form is the space surrounding its edge. Find the perimeter of various forms by summing the lengths of their sides.

Perimeter of the rectangle = 2(length+width)

Given the paramters are;

length  = x + 1

W = x + 1

Perimeter of the shape= x+1+1+x+x+1+x+1

Perimeter = x+1+1+x+x+1+x+1

= 4x + 4

This is the expression equivalent to the perimeter of the shape

The answer is c.

Answer:

X=14

Step-by-step explanation:

17^2+b^2=19^2

289+b^2=361

361-289=72

The square root pf 72 is ~8.5

subtract 17 from 31 (to get rid of the triangle bases on the bottom).

31-17=14

X=14

Answer:

Surface area = 207 cm²

Step-by-step explanation:

Surface are of triangular prism = 2×BA + P × H

Base Area (BA) = ½*bh

b = 8 cm

h = 9 cm

BA = ½*8*9 = 36 cm²

Perimeter of triangular base (P) = 8 + 9 + 10 = 27 cm

Height for prism (H) = 5 cm

Surface area = 2 × 36 + 27 × 5 = 72 + 135

Surface area = 207 cm²

Answer:

3, 2, 0

Step-by-step explanation:

trust me

The resultant value of vectors are:

1. z + w = -1 + 3i.

2. w - u= -4 - 4i

3. u + w = -4.

Given:

z = 2 + 5i

w = -3 - 2i

u = -1 + 2i

1. z + w:

Adding the real and imaginary parts separately gives

(2 + 5i) + (-3 - 2i) = (2 - 3) + (5 - 2)i

                          = -1 + 3i

Therefore, z + w is equal to -1 + 3i.

2. w - u:

Subtracting the real and imaginary parts separately gives

(-3 - 2i) - (-1 + 2i) = (-3 + 1) + (-2 - 2)i

                          = -4 - 4i

Therefore, w - u is equal to -4 - 4i.

3. u + w:

Adding the real and imaginary parts separately gives

(-1 + 2i) + (-3 - 2i) = (-1 - 3) + (2 - 2)i

                           = -4

Therefore, u + w is equal to -4.

Answer:

16 servings

Step-by-step explanation:

The recipe would use 2 pints or 4 cups of milk. 1 cup of milk is equal to 4 servings (20/5 = 4), so 4 cups would make 16 servings.

1 pint is equal to 2 cups so 2 pints will be 4 cups.

The number of servings 2 pints will make is 16 servings.

A unit rate means a rate for one of something.

It is written as a ratio with 1 as the denominator.

We have,

5 cups of milk = 20 servings

Multiplying 1/5 on both sides.

1/5 x  5 cups of milk = 1/5 x 20 servings

This means,

1 cup of milk = 4 servings

We know that,

1 pint = 2 cups

Multiplying 2 on both sides

2 x 1 pints = 2 x 2 cups

2 pints = 4 cups

If,

1 cup = 4 servings

4 cups = 4 x 4 servings
4 cups = 16 servings

Thus the number of servings 2 pints will make is 16 servings.

Answer: 8 servings

Step-by-step explanation:

1/2 cup + 1/2 cup = 1 cup

                                              >  1 cup + 1 cup = 2 cups = one pint

1/2 cup + 1/2 cup = 1 cup

if 4 servings go in one pint then 8 servings goes in 2 pint

8 cups/servings.

Answer:

[tex]\frac{x^2+2x}{x-3}[/tex]

Step-by-step explanation:

We need to factor out numerator and denominator in order to simplify the rational expression by cancelling  common factors.

Numerator :  x^3 - 4 x = x (x^2 - 4) = x (x - 2) (x + 2)

Denominator (factoring by grouping):

x^2 - 5 x + 6 = x^2 - 3 x - 2 x + 6 = x (x - 3) - 2 (x - 3) = (x - 3) (x - 2)

Then we can cancel out the common factor (x - 2) in both numerator and denominator, leading to:

x (x + 2) / (x - 3) = (x^2 + 2)/ (x-3)
