10x+3(2x+5)=19
10x+6x+15=19
16x+15=19
16x=4
x=4/16
x=1/4

3ay(a + 2y)^2
=3ay(a + 2y)(a + 2y)
=3ay (a^2 + 2ay + 2ay + 4y^2)
= 3ay (a^2 + 4ay + 4y^2)
= 3a^3y + 12a^2y^2 + 4y^3 a)
Answer:
51, 52, 53
Step-by-step explanation:
51, 52, and 53 are all greater than 50, but less than 54
Answer:
x=18
Step-by-step explanation:
the result of 12 added to the difference of half a number and 3 is 45.
that looks something like this
which can be solved as such
is differentiable across its domain, so the MVT says there is some value of
in the open interval
such that
You have
so the equation above becomes
Solve for
.
so
is indeed the average of the endpoints, i.e. the midpoint.
