Answer: B. -4 5/12
Step-by-step explanation:
Answer: Surface area of a triangular prism = 2*Area of Base (triangle) + Perimeter of Base (triangle)*Height
Step-by-step explanation: The sum of the areas of all the sides of the triangular prism is equal to the surface area. Thus, if you add all the areas of the sides you will get the surface area. The equation above is a faster way to do it.
Answer:
perimeter is the addition of all the length
(6.7+2.9+6.7+4.5)=
20.8
Answer:
Its geometric because each number is being divided by 2.
when you get this kind of exercise, you find need to find y or x in one of the exactions and fill it in in the other, however in this exercise the two y's are already given so all you need to do is replace the y in one of the exactions with the other exactions like this:
(keep in mind, you need to keep writing both of the exactions over again, otherwise you'll lose an exaction. and we'll need it later on)
y=-2x+6
y=3x-4
y=-2x+6
-2x+6=3x-4
y=-2x+6
-2x-3x=-4-6
y=-2x+6
-5x=-10
y=-2x+6
x= 2
and now replace the x in the first exaction with the x that we found:
y=-2(2)+6
x=2
y=-4+6
x=2
y=2
x=2
