Hey! Let me help you on this one.
In order for us to solve this problem, let's break it apart first.
is congruent to
, or in other words, they are the same.
As it stated, perimeter of
is 12 feet, and just like we mentioned before, both of these figures are perfectly congruent.
This means that both of these figures have the same perimeter as well!
Answer: The perimeter of CBD is 12 feet.
Franco played 30 minutes longer than Lian. Franco played for 120 minutes and lian 90, subtract those and you get your answer.
<h2>
Answer: y = 15x + 100</h2>
<h2>
Step-by-step explanation:</h2>
y = mx + b
y = mx + 100
How to find "m" or slope:
(0,100) and (20,400)
m = (y2 - y1) / (x2 - x1)
(400 - 100) / (20 - 0)
=> 300 / 20
=> 15
so
y = 15x + 100
I am going to do elimination
2x+3y=6
x+y=4
I multiplied the bottom one by -2
2x+3y=6
-2x-2y=-8
x cancels out
y=-2
Now to find the x
I am going to use the bottom equation
x+y=4
x+(-2)=4
x-2= 4
+2=+2
2 crosses out
x=6
So the answer is= (6,-2)
It will be in an ordered pair or coordinate.
