A composite figure is formed by combining a square and a triangle. Its total area is 57.5 ft2. The area of the triangle is 32.5 ft2. What is the length of each side of the square? Complete the explanation. The area of the square is ft2, so each side of the square is ft.
Answer:
Area of square = Composite Area - Area of Triangle
= 32.5 - 7.5 = 25
Area of square = 25 square feet.
Formula for area of square = s²
s² = 25
s = √25
s = 5
Length of each side of square = 5 feet.
Question:
A composite figure is formed by combining a square and a triangle. Its total area is 31.5 ft2. The area of the triangle is 15.5 ft2. What is the length of each side of the square? Complete the explanation.
Answer:
The area of the square is 16 ft², so each side of the square is 4 ft.

-64
Since -64<0 there are two imaginary (or ‘complex’) solutions.
Note: if d=0, there is one real solution. if d>0, there are two real solutions.
2x+45-56=9x+54+23
Solve for x please
Answer:
x = -12.57
Step-by-step explanation:
2x + 45 - 56 = 9x + 54 + 23
2x - 11 = 9x + 77
-11 = 7x + 77
-88 = 7x
x = -12.57
Quick prints makes custom t-shirts. They charge $10 for each t-shirt ordered plus a $5 design fee. Which situation best represents y, the total cost to order x t-shirts?
Answer:
y = 10x+5
Step-by-step explanation:
The price of each T-shirt = $10
Design fee on each T-shirt = $5
We need to find the expression for the total cost. Let the total cost be y. So,
Let he has ordered x T-shirts. So,
y = 10x+5
Hence, this is the required solution.

How would you simplify the expression represented by the diagram below? Four figures. The first consists of 4 squares each labeled 1. The second consists of 2 rectangles each labeled c. The third consists of 2 squares each labeled 1. The fourth consists of one rectangle labeled c.
Based on the description of the diagram, we get simplified expression is 6 + 3c.
Describe Algebraic Expression?An algebraic expression is a mathematical phrase that consists of variables, constants, and arithmetic operations (such as addition, subtraction, multiplication, and division), as well as exponentiation and roots. These expressions are used to represent mathematical relationships and formulas in a concise and standardized way.
Based on the description of the diagram, we can simplify the expression as follows:
There are 4 squares labeled 1, so their total value is 4.
There are 2 rectangles labeled c, so their total value is 2c.
There are 2 squares labeled 1, so their total value is 2.
There is 1 rectangle labeled c, so its value is c.
Therefore, the expression represented by the diagram simplifies to:
4 + 2c + 2 + c
6 + 3c
So the simplified expression is:
6 + 3c.

1. (10 points) Explain how to factor the following:
A: 3m2 + 4m +1 = 0
B: 16n- 25
C: 20n3 - 15n2 + 4n - 3
D: 864.3 + 4
Answer:
A. 3m² + 4m + 1 = 0
3m² + 3m + m + 1 = 0
3m (m + 1) + 1 (m + 1) = 0
( 3m + 1 ) (m + 1) = 0

Answer:
y= -5x+7
Step-by-step explanation:
since it is parallel, the gradient is the same
m=-5
y=mX+C
y=-5x + c
sub in the coordinate to get the y intercept
(2)= -5(1)+c
2+5 = C
C=7
therefore the ans is :
y= -5x + 7
