Step-by-step explanation:
|5| - |-3| is 2
Answer:
18.4 feet
Step-by-step explanation:
-use the formula C^2 = A^2 + B^2 for a right triangle, which is made by the ladder and the wall.
-let the ladder be C, the wall be a, the base to the bottom be b.
-substitude into the equation, which will leave us with:
C^2 = 17^2 + 7^2
C^2 = 289 + 49
C^2 = 338
C = square root of 338, which is 18.4 feet!
Here are some examples: 2+2=4, 5+-5=0 etc... Integers are positive numbers and negative numbers like: 5, 7, 100, -38.
So you use the distributive property. so, -3y+15=24
-3y=9
y=-3
Each truck weighs five tons.
1st truck: n
2nd truck: n + 2
3rd truck: n + 4
4th truck: n + 6
n + n + 2 + n + 4 + n + 6 = 32
4n + 12 = 32
- 12 - 12
--------------------
4n = 20
---- ------
4 4
n = 5
