Answer:
61
Step-by-step explanation:
3x + 6 = 183
3x = 177
x = 59
(x+2) = (59+2) = 61

Answer:
The measure of angle x is 122.5 degrees.
The measure of angle y is 57.5 degrees
Step-by-step explanation:
180=y+x
y=x-65
180= (x-65)+x
180=2x-65
245=2x
x=122.5
y=122.5-65= 57.5
The height of the square pyramid exists 2 units.
<h3>How to estimate the area of the base of the square pyramid?</h3>
Volume of the square pyramid

where B exists in the area of the base H lives at the height of the pyramid
we have H = 6 
V = 70 
substitute in the formula and solve for B, we get

B = 
= 35 
To estimate the height of the square prism
Volume of the square prism = Bh
Where B exists the area of the base
h exists the height of the prism
we have B = 35 and V = 70
substitute in the formula and solve for h
70 = (35)h
h = 2 units.

Answer:
<h2>(0.3, -18.45).</h2>
Step-by-step explanation:
We need to recur to the extreme value theorem, which states: "If a function is continuous on a closed interval, then that function has a maximum and a minimum inside that interval".
Basically, as the theorem states, if a dunction is continuous, then it has maxium or minium.
In this case, we have a quadratic function, which is a parabola. An important characteristic of parabolas is that they have a maximum or a minium, but they don't have both. When the quadratic term of the fuction is positive, then it has a minium at its vertex. When the quadratic term of the function is negative, then it has a maximum at its vertex.
So, the given function is
, where the quadratic term is positive, so the functions has a minimum at
, where
and
, let's find that point
<h3>

</h3><h3>

</h3><h3 /><h3>Therefore, the minium of the function is at (0.3, -18.45).</h3>
