The lengths of the two legs of a right triangle are 4 and 7. What is the length of the
hypotenuse? Express answer in Simplified Radical Form.
Answer:8.06
Step-by-step explanation:
4 x 4= 16 7 x 7 = 49
49+16=65
square root of 65 =8.06
Answer:
[tex] \sqrt{65} [/tex]
Step-by-step explanation:
To find the hypotenuese of a right angle you use the pythagreon theroem.
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
a and b are the height and base, while c is the hypotenuese. simply insert the values in the equation and find the variable.
[tex] {4}^{2} + {7}^{2} = {c}^{2} \\ 16 + 49 = {c}^{2} \\ 65 = {c}^{2} \\ \sqrt{65} = c[/tex]
The radical form answer is above, otherwise it would be a decimal.

An equation is shown below:
5(3x − 4) = 1
Which of the following correctly shows the first two steps to solve this equation? (1 point)
Group of answer choices
Step 1: 8x + 1 = 1; Step 2: 8x = 0
Step 1: 8x − 9 = 1; Step 2: 8x = 10
Step 1: 15x − 20 = 1; Step 2: 15x = 21
Step 1: 15x − 4 = 1; Step 2: 15x = 5
9514 1404 393
Answer:
(C) Step 1: 15x − 20 = 1; Step 2: 15x = 21
Step-by-step explanation:
The first step is to eliminate the parentheses, using the distributive property.
5(3x − 4) = 1
15x -20 = 1
The second step is to add 20 to both sides of the equation.
15x = 21
This pair of steps is shown in the 3rd choice.
_____
Comment on the answers
The distributive property seems to be applied incorrectly a lot of the time. Here, you can choose the correct answer by looking at the result of properly applying the distributive property: 5(3x-4) = 15x-20. Only the correct choice has this as the first step.
