Answer:
Step-by-step explanation:
The number of adults in the family that is going to the amusement park is 2.
The number of children in the family that is going to the amusement park is 4.
Admission is a 21 point 75 for adults and 15 point 25 for children. This means that the admission cost for each adult is 21.75 and the admission cost for each adult is 15.25. Therefore,
The total cost of admission for the 2 adults would be
21.75 × 2 = 43.5
The total cost of admission for the 4 children would be
15.25 × 4 = 61
Therefore, the total cost of the families admission would be
43.5 + 61 = 104.5
The formula is <span>base × height / 2
So 8.7 x 15.6=135.72 / 2= 67.86

Well, I don’t necessarily remember how to sketch a plane. However, I can help get you started by defining some words they use and hopefully you will be able to do this on your own!
So this plane is made up of three points, names E, D and B. (Edit: This plane may be made up of four points, because of point A.)
E and B are collinear with A. This basically means that they all are on the same line.
D is a vertex. This basically means that it is a dot that these two lines called rays will shoot out of it. I will attach a picture of a vertex.
CD and FD are called rays. See those little lines above them? I’ll be sure to attached another image so that you know what I’m taking about. Anyway, that means they are rays. Rays are like never ending lines; they start at a point and the line will go on for infinity.
(Edit: where did the point f come from? I really wish you would have attached the full picture...)
Whelp, that’s all I’ve got! Good luck!!
(Edit: looks like I can only attach one picture...I’ll comment the other.)
Answer:
12x² - 6; 21 inches ⇒ A
Step-by-step explanation:
Let us solve the question
∵ The side lengths of a triangle are 4x² - 3 in., 4x² - 2 in., 4x² - 1 in.
∴ S1 = 4x² - 3 inches
∴ S2 = 4x² - 2 inches
∴ S3 = 4x² - 1 inches
→ The perimeter of the triangle is the sum of the lengths of its 3 sides
∵ P = S1 + S2 + S3
∴ P = 4x² - 3 + 4x² - 2 + 4x² - 1
→ Add the like terms
∵ P = (4x² + 4x² + 4x²) + (-3 + -2 + -1)
∴ P = 12x² + -6
→ Remember (+)(-) = (-)
∴ P = 12x² - 6
∴ The expression of the perimeter of the Δ is 12x² - 6
∵ x = 1.5
→ Substitute x in the perimeter expression by 1.5
∵ P = 12(1.5)² - 6
∴ P = 12(2.25) - 6
∴ P = 27 - 6
∴ P = 21 inches
∴ The perimeter of the triangle is 21 inches
The expression can be used to find the perimeter of the triangle is 12x² - 6 and its perimeter is 21 inches when x = 1.5
In all the cases, the number is multiplied by itself and added 1 to it. so the answer is 26
