Answer:
A. 13, 10, 16
Step-by-step explanation:
If three sides of triangle have measures a, b and c, then
Check all options:
A. a=13, b=10, c=16
Thus,
This option is true
B. a=1, b=2, c=3
Then
but 
must be greater than c, so
this option is false
C. a=5.2, b=11, c=4.9
Then
but 
must be greater than b, so
this option is false
D. a=208, b=9, c=219
Then
but must be greater than c, so
this option is false
If 1 inch = 2.5 yards then
x inch = 80 yards
cross multiplying we have:
80 × 1 = x × 2.5
x = 80÷ 2.5 = 32 inches
therefore the picnic area is 32 inches in the drawing.
Potential energy is going to be in the middle. It goes kinetic-potential :)
Answer:
Step-by-step explanation: the discount on the original price is a 20% discount, so it is 20% of x, or 0.2x.
We are told the discount is $3, so 0.2x = 3. Now we solve the equation for x.
0.2x = 3
Divide both sides by 0.2.
x = 3/0.2
x = 15
The regular price is $15.
Answer:
A. -2x^2-2x-2
Step-by-step explanation:
(2x^2-5x-4)-(4x^2-3x-2)
distribute the minus sign
(2x^2-5x-4)-4x^2+3x+2
2x^2-5x-4
-4x^2+3x+2
-------------------------
-2x^2 -2x-2
