The perimeter of a pentagon is 48. One side is equal to x, two sides are twice x and two sides are three more than x. What are t

DochEvi [55]

Answer:

side lengths are 6, 12, 12, 9, 9

Step-by-step explanation:

The perimeter is the sum of the lengths of the sides:

x + 2x + 2x + (x+3) + (x+3) = 48

7x +6 = 48 . . . . collect terms

7x = 42 . . . . . . .subtract 6

x = 6 . . . . . . . . . divide by 7

Substitute this value into the expressions for the side lengths:

x = 6

2x = 12

x+3 = 9

The side lengths are 6, 12, 12, 9, 9.

Answer:

Option P √2.5²-1.2²

Step-by-step explanation:

a = distance between Toby's House and the playground = 1.2 inches

b = distance between the playground and Toby's Friend's House = unknown

c = distance between Toby's House and Toby's Friend's House = 2.5 inches

Use the Pythagorean Theorem to calculate the side length of b:

a²+b²=c²

b²=c²-a²

b=√(c²-a²)

b=√(2.5²-1.2²)

Therefore, option P is correct.

The inverse of the function f(x) = x + 10 is shown.

Vadim26 [7]

we have

$f(x) = \frac{1}{2}x + 10$

Step $1$

Let

y=f(x)

$y = \frac{1}{2}x + 10$

Exchange the variable x for y and variable y for x

$x = \frac{1}{2}y + 10$

Clear variable y

Multiply by $2$ both sides

$2x = y + 20$

$y = 2x-20$

Let

$f(x)^{-1} =y$

$f(x)^{-1}=2x-20$

therefore

the answer is

the inverse of the function is $f(x)^{-1}=2x-20$

the missing value is $20$
