A Square Window would have four equal sides. So you would use the <span>Pythagorean Theorem (a</span>²+b²=c²) to solve the problem. so it would be set up like this; 40²+40²=c². then you would evaluate it and it become:
400+400=c²
800=c²
√800=√c²
Answer: 28.3 inches
The subtraction gives -7x^2( x + 1) - 3
<h3>What are algebraic expressions?</h3>
Algebraic expressions are expressions are expressions that are made up of factors, terms, variables and constants.
They also consist of arithmetic operations.
We have to subtract (6x^3 − x^2 + 8x + 5) from (−x^3 − 9x^2 + 2)
It is written as;
(−x^3 − 9x^2 + 2) - (6x^3 − x^2 + 8x + 5)
−x^3 − 9x^2 + 2 - 6x^3 + x^2 - 8x - 5
collect like terms
-x^3 - 6x^3 - 9x^2 + x^2 + 2 - 5
Add like terms
-7x^3 - 7x^2 - 3
To simply further
-7x^2( x + 1) - 3
Thus, the subtraction gives -7x^2( x + 1) - 3

Answer:
18x+20y≤ 230
Step-by-step explanation:
step one
given data
A black sweatshirt costs $18, and a white sweatshirt costs $20
let x be the number of black and
let y be the number of white sweatshirts
step two:
Also, we are told that the club plans to spend no more than $230
hence the inequality for the situation is
18x+20y≤ 230
