The first thing we must do for this case is to define a variable.
We have then:
n: unknown number.
We write the algebraic expression:
13 - 4n
For n = 3 we have:
13 - 4 (3) = 13 - 12 = 1
Answer:
An expression that represents this phrase is:
13 - 4n
its value if n = 3 is:
1
Imagine the side of the building is one side to a triangle and the second would be from the top of the building to the point where the shadow ends and the third is from the base of the building to the point where the shadow ends. Just use the pythagoreon theorem to find stuff. I can't solve the problem you gave because you would need the height of the building
Answer:
-48.1818
Step-by-step explanation: then u round up to 3 singnificant figures
4y+25=3y+20
4y+5=3y
***y=5***
so you plug y into both
4(5)+25 and 3(5)+20
45, 100, and 35 are the measurements of the angles.
