Answer:
x=12, y=30
Step-by-step explanation:
to find x:
in a equilateral triangle, all three sides are congruent, so:
4x-4=3x+8
x-4=8
x=12
to find y:
in an equilateral triangle, all the angles are 60°, so:
2y=60
y=30°

2. -2r
3. g-4
4. 5f+4
5. 15z
Answer:
Step-by-step explanation:
For this case we have the following value:
We can convert this first to 
like this:
Now we use the fact the the pressure is defined as 
, whre P is the pressure, F the force and A the area, so then 
and then we can replace this:
Now from definition of work we know that 
where W is the work, F the force and d the distance, so then is equivalent 
And if we replace this into the equation we got:
Answer:
90
Step-by-step explanation:
1125/100=11.25
11.25x8=90
Pi(r)(r)(2) + pi(diameter)(height)
3.14(4)(4)(2)+ 3.14(8)(1.5)
138.16
