The answer is true, because there is only one number that can be squared to twelve.
Answer:
Step-by-step explanation:
We are given the area of square A as 40 ft². Then we are told that the area of square B is 250% of A's area. The equation in words that we are going to be using is:
Area of square B = 2.5 × Area of square A where the word "is" is replaced by an equals sign, and the word "of" is replaced by a multiplication sign. We know that the area of A is 40, so:
Area of square B = 2.5(40) and
Area of square B = 100 ft²
The area formula for a square is A = s², so if the Area is 100:
100 = s² so
s = 10ft

Answer:
For 7, it's around 20 minutes. For 6, it's around 30. For 8, it's around 15.
Four numbers has a sum of 1764 and the value of one of those numbers is 1029.
Use algebraic expressions to solve for the value of n.
Algebraic expression is an expression which is made up of variables and constants, along with algebraic operations (addition, subtraction, etc).
One of the four numbers is already denoted as variable n. Let m be the sum of the three other numbers.
If the sum of the four numbers is 1,764, then:
n + m = 1764
If n is 40% more than the sum of the other three numbers, then:
n = 40% m + m
n = 1.4 m
Substitute n from the 2nd equation to the 1st equation.
n + m = 1764
1.4 m + m = 1764
2.4 m = 1764
m = 735
Recall that n = 1.4 m.
n = 1.4 (735)
n = 1029
