Answer:

Perimeter of rectangle = 14x - 2

Area of rectangle = 10x² + x - 2

Step-by-step explanation:

Finding the perimeter of the rectangle:

⇒ Perimeter of rectangle = 2(L) + 2(B)

⇒ Perimeter of rectangle = 2(2x + 1) + 2(5x - 2)

⇒ Perimeter of rectangle = 4x + 2 + 10x - 4

⇒ Perimeter of rectangle = 14x - 2

Finding the area of the rectangle:

Area of rectangle = LB

⇒ Area of rectangle = (2x + 1)(5x - 2)

⇒ Area of rectangle = 10x² - 4x + 5x - 2

⇒ Area of rectangle = 10x² + x - 2

Answer:

Perimeter = 14x - 2

Area = 10x² + x - 2

Step-by-step explanation:

Formulae

Perimeter = 2W + 2L
Area = W x L

(where W is the width and L is the length)

Given information

width = 2x + 1
length = 5x - 2

Perimeter

⇒ Perimeter = 2(2x + 1) + 2(5x - 2)

= 4x + 2 + 10x - 4

= 14x - 2

Area

⇒ Area = (2x + 1)(5x - 2)

= 10x² - 4x + 5x - 2

= 10x² + x - 2

PLEASE HELP!! WILL GIVE BRAINLIEST!!!

Answer:

option D

Step-by-step explanation:

Jerry solved this equation:

$3(x-\frac{1}{4})=\frac{13}{6}$

In the first step , she multiplied 3 inside the parenthesis

1. $3x-\frac{3}{4}=\frac{13}{6}$

In step 2, 3/4 is added on both sides

2. $3x-\frac{3}{4}+\frac{3}{4}=\frac{13}{6}+\frac{3}{4}$

In step 3, we take LCD 12

3. $3x=\frac{26}{12}+\frac{9}{12}$

In step 4, add the fractions

4. $3x=\frac{35}{12}$

Here, 3 or 3/1 are same.

$\frac{3}{1}x=\frac{35}{12}$

In step 5, to remove 3/1 we multiply both sides by 1/3.

Instead of multiplying 1/3 , Jerry made an error by multiplying 3/1

$\frac{1}{3} \cdot \frac{3}{1}x=\frac{1}{3} \cdot \frac{35}{12}$

$x=\frac{35}{36}$

In step 5, he should have multiplied both sides by 1/3

What function was used to make that pattern

Semenov [28]

Answer:

Step-by-step explanation:

The differences in the terms of f(x) are + 3, + 5, + 7

Since the differences are not constant the relationship is not linear

Note the differences in the differences are + 2, + 2,

The second differences are constant indicating a quadratic relationship

Note the relationship between x and f(x)

x = 1 → 1² = 1 ← require to add 5, that is 1 + 5 = 6 ← value of f(x)

x = 2 → 2² = 4 ← require to add 5, that is 4 + 5 = 9 ← value of f(x)

x = 3 → 3² = 9 ← require to add 5, that is 9 + 5 = 14 ← value of f(x)

x = 4 → 4² = 16 ← require to add 5, that is 16 + 5 = 21 ← value of f(x)

Thus f(x) = x² + 5 → B
