The value of number will be;
⇒ 11
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Bob was thinking of a number between 5 and 15 that when squared and added to 23 equals the next number's square.
Now,
Let the value of number = x
Hence, We can formulate;
⇒ x² + 23 = (x + 1)²
Solve for x as;
⇒ x² + 23 = x² + 1 + 2x
⇒ x² - x² + 23 - 1 = 2x
⇒ 22 = 2x
⇒ x = 22/2
⇒ x = 11
Thus, The value of number will be;
⇒ 11

Answer:
11
Step-by-step explanation:
(11)² = 121
121+23 = 144
(12)² = 144
A (1,-2) B (-2,-8)
Linear functions!
c = 4w + 3
c = w + 9
c = w – 3
w = c + 9
w = c – 3
w = c – 9
w = 4c + 3
c=w+9 and c=w-3
w=c-9 and w=c+3
These pairs of equations are best relationship models between c and w.
How to find pair of best relationship model for c and w?
We have given,
Variable c is 9 more than variable w which can be written as
c=w+9
It can also be written as :w=c-9
It is also given that,Variable c is also 3 less than variable w, which can be written as:
c=w-3
It can also be written as: w=c+3
This way our pair of relationship between c and w are:
c=w+9 and c=w-3
w=c-9 and w=c+3

Answer:
True
Step-by-step explanation:
According to the Angle Sum property of triangle, Sum of all interior of a triangle is equal to 180°.
If there is more than one obtuse angle in a triangle then Sum of both obtuse angle exceed the maximum sum of all three angle of a triangle. Which contradict the Angle Sum Property of triangle.
So, It is impossible to have a triangle with two obtuse angles.
Only possible is a triangle with 1 obtuse angle with 2 acute angles.
Therefore, Answer for given statement is TRUE
