Answer:
40
Step-by-step explanation:
Find the area of each side and add them together. The area of triangles equals Height time 1/2base so you get a=1/2(4)(3). A=6. 6+6+6+6=24 plus the base which is 4x4=16. 26+16=40
40 is our final answer
Answer: 2x-5 / x+5
Step-by-step explanation:
(2x^2 - 3x - 5) / (x^2 + 6x + 5)
Write -3x as a difference
= (2x^2 +2x - 5x -5) / (x^2+5x+x+5)
Factor out 2x from the expression
= 2x *(x+1) -5 * (x+1) / x*(x+5)+x+5
Factor out x+1 from the expression
= (x+1) * (2x-5) / (x+5)* (x+1)
Reduce the fraction with x+1
= 2x-5 / x+5
Mathematical proofs are important because they help to explain concepts. They also serve as concrete validation for a mathematical result or statement.
- In geometry, an incorrect conclusion within a proof might lead to wrong estimations of size, length, and other spatial properties.
- Algebra, topology, arithmetics, calculus, and statistics are some other branches of mathematics. In statistics, an incorrect conclusion within a proof might lead to the wrong interpretation of bulky data. Statistical properties like the mean, median, and mode can be misinterpreted.
- Businesses that rely on statistics for production and forecasting might be affected.
<h3>What is a Mathematical proof?</h3>
A proof in mathematics is a number of conclusions that lead to the justification of a final statement.
Having incorrect mathematical proofs can be dangerous because it will cause the misinterpretation of concepts and the obtaining of wrong results.
