Step-by-step explanation:
The measures of a trinagle is A=1/2b x h
THIS IS SO EASY!
Use the method of "Writing it as a sum". (meaning use addition signs.)
Use commutative property (Change order of expression of the same signs).
How to solve:
1.) They are all negatives so add.
-24 + (-26) + (-8)
-24 + - 26 + -8 They all have the same signs)
-50 + -8
-58
When you are writing it as a sum, you're basically adding it's additive inverse.
The statements that agree with the graph of the equation are as follows:
<span>4.the function is decreasing over the interval (−4, ∞).
</span><span>1.the domain is {x|x ≤ –2}.
I hope my answer has come to your help. God bless and have a nice day ahead! Feel free to ask more questions.

Answer:
this means that at average sea level, the elevation is zero. in reality, the level of the sea rises and falls in what are called tides. low tide is the point.who is drake?
Step-by-step explanation:
Answer:
Dimensions are 20 X 44 feet
Step-by-step explanation:
First we need to build two equations:
For area X times Y = 880
For Perimeter 2x + 2y = 128
Now we need to solve one so we can substitute it into the other:
2x + 2y = 128 becomes
2x = 128 - 2y and then
x = 64 - y We will substitute this into the are equation
(64 - y)y = 880
64y - 
= 880
-
factor out the negative
-(
Factor:
-(y - 20)(y - 44) = 0
y-20 = 0 and y - 44 = 0
y = 20 and y = 44
Plugging these in two both of our formulas works
20 X 44 = 880 for area
2(20) + 2 (44) = 128 for perimeter
