The first problem’s answer is true. (P.S. If you don’t understand this type of problems then plug in variables for them. It helps check your answer and solve them too.)
The second problem’s answer is false.
First of all, I plugged in for the variable a to be 6 for the first problem. Second, I plugged in numbers for the variables and x was 5 and x was 2 for the second problem. You can check the steps in the image I took. (P.S. You can use the MathPapa calculator online to solve these problems and plug in the variables.)
(I couldn’t upload the second problem’s step by step sorry, but if you need it then just use the MathPapa calculator by plugging in numbers for the variables.)
Answer:
21.5
Step-by-step explanation:
Just find the find the difference between 34 and 77 (even though 34 is a negative) then half the answer.
A non-negative root of a number is called Square Root
Answer:
37 ft
Step-by-step explanation:
The Pythagorean theorem tells you the length of the diagonal is the square root of the sum of the squares of the side lengths:
diagonal = √(30^2 +22^2) = √1384 ≈ 37 . . . . feet
First, add hours until the difference is less than an hour. You can add 3 hours on to make it 9:32 p.m. Then, add minutes on until it's the exact time. from 9:32 to 9:48, you can add 16 minutes, so the total time in the movie was 3 hours, 16 minutes.
