Answer:
A
Step-by-step explanation:
Answer: 10
Explanation:
20 ÷ (4- (10-8))
First off, you work your way outward. You start the furthest in, then head your way out. (10 - 8) is the furthest in, and 10 - 8 = 2. So now your equation looks like this:
20 ÷ (4 - 2)
Next, you do the (4 - 2) which equals 2. So now, the equation is this:
20 ÷ 2
So you finish it up with 20 ÷ 2 which equals 10.
Hope I made sense! :D
Answer:
slope = - 
Step-by-step explanation:
the slope of the secant line in the closed interval [a, b ] is
slope = 
here [a, b ] = [1, 4 ]
f(b) = f(4) = -
+ 5 = - 16 + 5 = - 11
f(a) = f(1) = -
+ 5 = - 2 + 5 = 3
slope =
=
= - 
So if the area of a square is 320 square meters, then because all four sides are equal, you would end up with the equation

which simplifies to
