Vertical angle is when opposite angles meet in the middle of two intersecting lines (share the same vertex). They are equal to each other too.
Hope this helps! :)
A person with a hat who knows all about that don’t rock that sat with a cat in a hat knows all about that
4x=3(x-6)-2
distribute
4x = 3x-18 -2
combine like terms
4x =3x-20
subtract 3x from each side
x = -20
Answer:
7x^2+21x+14
Step-by-step explanation:
With this all we have to do is foil:
first outside inside last
first: 7x^2
outside: 14x
inside: 7x
last: 14
we now combine them to
7x^2+14x+7x+14
we add like terms
7x^2+21x+14
Answer:
dx/dt= 0.2608 at h= 3.1 m
Step-by-step explanation:
a is the length of the ladder. a=5
by pythagorus theorem
differentiating with respect to t we get
......1
The variable h is the height of the ladder's top at time t, and x is the distance from the wall to the ladder's bottom
At h= 3.1
x^2= 6^2-3.1^2 = 9.1×2.9
x= 5.1371 m
given
putting values in 1 to get dx/dt
.
dx/dt= 0.2608 at h= 3.1 m
