Answer:
a.) 5x
b.) 6xy
c.) 6xy
Step-by-step explanation:
5 * x = 5x
6 * x * y = 6xy
2 * x * 3 * y = 6xy
The equation v in terms of other variables is v = kr/2h
<h3>What is the subject of an equation?</h3>
It is a variable which is expressed in terms of other variables involved in the formula.
Formulas are written so that a single variable, the subject of the formula is on the L.H.S. of the equation. Everything else goes on the right side of the equation. We evaluate the formula by substituting for the literal numbers on the right hand side.
2(vh) / k = r
by cross multiplication
2(vh) = kr
divide both sides by 2h
v = kr/2h
In conclusion, v in terms of other variables is kr/2h

Answer:
Step-by-step explanation:
We can rewrite the square root of negative 18 as 
. We can evaluate these two quantities separately. The square root of 18 can be factored to get 3 squared times 2. We can take the 3 out to get 
. Now, the square root of negative one can be rewritten as 
, so this is equal to
One solution.
They have different slopes and therefore have one solution.
All internal angles in a quadrilateral add to 360
so
x+110+110+70=360
x+290=360
minus 290 both sides
x=70 degrees
