Step-by-step explanation:
A school is planning to construct two rectangular play areas in the playground.
The length of play area A must be 1 foot longer than four times its width. The width of play area B must be 2 feet longer than the width of play
area A, and the length must be 2 feet longer than three times its own width. In
addition, the areas of the two play areas must be equal.
Write a system of equations to represent this situation, where y is the area of the play areas and x is the width of play area A. Which statement
describes the number and viability of the system's solutions?
ОА.
The system has two solutions, but only one is viable because the other results in a negative width.
B.
The system has only one solution, and it is viable because it results in a positive width.
c. The system has two solutions, and both are viable because they result in positive widths.

In Eduardo's collection, the number of butterflies is 12 more than twice the number of moths. If there are x moths, choose the expression that represent the number of butterflies he has.
Answers
Answer:
y = 12 + 2x
Step-by-step explanation:
Given that :
Let number of butterflies = y
Number of moths = x
y = 12 more than twice the number of moths
y = 12 + 2x
Hence, the expression which relates the number of butterflies he has is :
y = 12 + 2x

Figures 1 and 2 below show two polygonal regions used to approximate the area of the given shape. Find the average area, in square units, of the given shape using figures 1 and 2.
Answers
Answer:
figure 1 is 8.5 units^2 and figure 2 is 3 units^2 and the average are is 5.25 units^2
The overestimated area, the underestimated area, and the average area will be 8.5 units², 3 units², and 2.75 units², respectively.
What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
Since the area is covered with either a square or a triangle. Therefore, we can write the area of this two as,
Area of a square = 1 unit × 1 unit = 1 unit²
Area of triangle = 0.5 × 1 unit × 1 unit = 0.5 units²
The overestimated area, the number of square and triangles are,
Number of square = 6
Number of triangle = 5
Total overestimated area = (6×1unit²) + (5×0.5unit²) = 8.5 unit²
The under estimated area, the number of square and triangles are,
Number of square = 2
Number of triangle = 2
Total Underestimated area = (2×1unit²) + (2×0.5unit²) = 3 unit²
Furthermore, the average area is,
Average area = (Total overestimated area - Total Underestimated area)/2
= (8.5 units² - 3 units²) / 2
= 5.5 units² / 2
= 2.75 units²
Hence, the overestimated area, the underestimated area, and the average area will be 8.5 units², 3 units², and 2.75 units², respectively.

Answers
Answer:84.84m^2
Edit: I redid it doing the base separate and got 84.847 because Pythagorean theorem tells you the sides of the three triangles are 6.998 which is ever so slightly smaller than the base triangle.
Step-by-step explanation:
This is assuming the triangles are equal. 1/2bh gives you 21.21 for the triangle with the given height and then multiplying that by four for all the sides gives you 84.84m^2. The question doesn’t specify what type of pyramid it is so again I’m assuming it’s equal. Not 100% positive hope it can help at all.

The volume (353 m^3) of this rectangular prism is equal to b(ase) x h(eight) x w(idth).
So we can create the equation: 352 = bhw = (8)(11)h = 88h
