The pythagorean theorem works for all right triangles. Just make sure it IS a right triangle.
The answer is 12. Thanks (;
3(x-1)-8=4(1+x)+5
One solution was found :
x = -20
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
3*(x-1)-8-(4*(1+x)+5)=0
Step by step solution :
Step 1 :
Equation at the end of step 1 :
((3•(x-1))-8)-(4•(x+1)+5) = 0
Step 2 :
Equation at the end of step 2 :
(3 • (x - 1) - 8) - (4x + 9) = 0
Step 3 :
Step 4 :
Pulling out like terms :
4.1 Pull out like factors :
-x - 20 = -1 • (x + 20)
Equation at the end of step 4 :
-x - 20 = 0
Step 5 :
Solving a Single Variable Equation :
5.1 Solve : -x-20 = 0
Add 20 to both sides of the equation :
-x = 20
Multiply both sides of the equation by (-1) : x = -20
One solution was found :
x = -20
hope this is wht u wanted
Answer:
Store 1 has the better deal.
Explanation:
If you divide the amount the prices by the amount of paper towel roll, you would see store 1 has the better deal.
3.60 divided by 12 = 0.30
3.50 divided by 10 = 0.35
As you can see, store 1 is less expensive than store 2. Therefore, store 1 is the better deal.
