Answer: x = 20 units

Step-by-step explanation:

     Since this is a right triangle, we can use the Pythagorean theorem (c is the hypotenuse and a & b are the legs.);

           a² + b² = c²

a² + b² = c²

(21)² + (x)² = (29)²

441 + (x)² = 841

(x)² = 400

x = \sqrt{40} = 20

Answer:

Answer x   = 20                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            

Step-by-step explanation:

Givens

c =29

a = 21

b =  ?

Formula

c^2 = a^2 + b^2                       Substitute the givens into the formula

Solution

29^2 = 21^2 + b^2                   Expand

841 = 441 + b^2                        Subtract 441 from both sides

841 - 441 = 441 +441 +  b^2

400 = b^2                                Take the square root of both sides.

√400 =  √b^2

20 = b

Answer

x = 20

Need help with this equation
NeX [460]

Answer:

D. 28x + 14 + 3 = - 67

Step-by-step explanation:

Given 7 ( 4x + 2 )  + 3 = - 67

our first step would be to distribute the 7

7 * 4x = 28x

7 * 2 = 14

we would be left with 28x + 14 + 3 = -67 which corresponds with "D"

A function is created to represent the miles per gallon your car gets. What restrictions would be made to the domain?. a. The do
Ahat [919]

Answer: d. The domain would only include positive numbers.

Step-by-step explanation:

Given: A function is created to represent the miles per gallon your car gets.

Here, the independent variable = the amount of fuel the car gets in gallons.

and the dependent variable = the total miles of car travel .

We know that the domain of a function is a set of all values of independent variable.

Thus, the domain would only include positive numbers because the quantity of fuel in a car is never negative and it can be in fraction .

Hence, D is the right answer.
