That’s false because two lines are to short so it’s false
Answer:
r= -5 , r= 17
Step-by-step explanation:
5|-6+r|=55
solve for 'r'
First we isolate absolute function
We divide both sides by 5
|-6+r| = 11
for absolute function we consider two cases, one with positive and one with negative. Now we make two equations
-6+r = 11 or -6+r = -11
Now solve both equations
-6 + r= 11
Add 6 on both sides
so , r= 17
-6 + r= -11
add 6 on both sides , so r= -5
If it's a perfect square, that means all four sides are equal in length, meaning the dimensions of length and width are the same.
Area=base*height
The only identical numbers that work to get 100 square feet is 10*10
So, all four lengths around the square are 10 feet, so that's 10 feet*4 sides.
You'd need 40 feet of fencing.
Answer:
see explanation
Step-by-step explanation:
Given
(x + 2)(x - 7) = 0 ← in standard form
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 7 = 0 ⇒ x = 7
Thus the zeros are x = - 2 and x = 7
