3rd period is 85:5
fractionify and simplify
85/5=17/1
17:1
7th period is 51:3
51:3
51/3
17/1
17:1
if they are proportional, then they are equal when simplified
17:1 is 3rd period
17:1 is 7th period
they are equall
they are poropoertional

Answer:
11
Step-by-step explanation:
Pulg in 2 into the equation x+3^2
I dont know if theres supposed to be a parenthese like but if there isn't then it would be 2+ which is 2+9
if there is parenthese... it would be:
= =25
That is the multipliative identity property.
Hey there, Ashytyn!
Area of a triangle, any triangle, is defined as base times height divided by two.
Why?
Think about if this right triangle was a rectangle. You'd multiply the four times the two for the area, right? Now we first have to realize that this triangle is half of a rectangle, and <em>that's why</em> we divide by two.
Therefore, we have:
A =
A = 2(4)/2
A = 8/2
A = 4 units squared.
Hope this helps!
