Answer:
7
Step-by-step explanation:
= AC × CB
= ( x + 9 ) 9
144 = 9x + 81
9x = 144 - 81
9x = 63
x = 63 ÷ 9
x = 7
Your answer is b so there you go have a great day!!!!
Recall that the volume of a regular prism is given by the area of the base times the height.
Given that the base of the prism is a regular pentagon with an apothem of 2.8 centimeters.
The pentagon consist of 5 isosceles triangles with the apothem as the height and the side of the pentagon as the base.
Recall that the are of a triangle is given by 1/2 base times height.
Thus the area of of the pentagon base of the prism is given by

Therefore, the volume of the prism is given by
We have been given two functions
and
. We are asked to find
.
We will use composite function property
to solve our given problem.
Now we will combine like terms as:


Therefore, the value of
would be
.
The answer is the square root of 101.75
Assuming that the sandwich Is a square, after cutting it diagonally, it turns into 2 triangles. To look for a missing length of a triangle, you use Pythagorean’s theorem a^2+b^2=c^2
Since c is 12 and a is 6.5 you just square 12 and square 6.5
144 42.25
Subtract it
101.75
You then have to find the square root of it. You can leave it as it is as √101.75 or just solve for it and round it to 10.09
