Answer:
400
Step-by-step explanation:
u = 50 km/hr
v = 100 km/hr
d = 300 km
b = 200 km/hr
= b*d/(u+v)
= 200* 300/(50+100)
= 400
Answer:
–5(8x – 4y”) 5. a(4x” – 6y + 1) 6. c(2a + b + 3c) 7. x(3x” – 2x +5) 8. y(3x + 2y” + 4y) 9
Step-by-step explanation:
Hi my dear friend,
A trinomial is a perfect square trinomial if it can be factored into a binomial multiplied to itself. (This is the part where you are moving the other way). In a perfect square trinomial, two of your terms will be perfect squares.
~Thank you
B) No, because opposite sides are not parallel
Step-by-step explanation:
Given this information, assume that quadrilateral WXYZ is a parallelogram then we expect;
Parallel sides to be : WX // YZ and XY // WZ
Additionally, we know parallel sides have equal gradient thus;
The slope of side WX= slope of side YZ and the slope of side XY= that of side WZ
However, from the information given, m of WX= 1/3 and that of YZ is -3, thus the two sides are not parallel to each other but perpendicular to each other because the product of their slope equals -1.

F(x) basically just substitutes the "y"
so you would bring everything over to one side
y + 3 = 0
subtract 3
y = -3
then
f(x) = -3
That is B)
