Answer:
1. 23
2. 5.83 (5.8 rounded)
3. 1.18 (or 1.2 rounded)
4. unsure how to solve, sorry
Step-by-step explanation:
your formula: a^2+b^2=c^2
1. 20^2+13^2=c^2
400+169=569
(take the square root of 569)
c=23
2. 15^2+b^2=17^2
225+b^2=289
(subtract 225 from both sides)
b^2= 34
(take the square root of 34)
b=5.83 (or 5.8 rounded)
3. 0.2^2+b^2=1.2^2
0.04+b^2=1.44
(subtract 0.04 from bot sides)
b^2=1.4
(take the square root of 1.4)
b=1.18 (or 1.2 rounded)
4. unsure how to solve, sorry

use a number line to find the difference-6.5 - 2
Answers
Answer:
The answer would be -8.5
Step-by-step explanation:
If you start at -6.5, to find the difference (subtract) you would move left two whole spaces to get to -8.5.
On the other hand, if you were to start at 6.5 and subtract 2, your answer would be 4.5.
It depends if your first number is negative or positive.

Which of the following correctly solves this equation? ( − 6 ) 2 − ( 6 ) ( 6 ) = 36 ( − 6 ) ( − 2 ) = 12 ( − 6 ) ( − 6 ) = 36 ( − 6 ) ( − 6 ) = − 36
Answers
The correct solution are: ( − 6 ) ( − 2 ) = 12 and ( − 6 ) ( − 6 ) = 36 .
Addition Sign Rules
Here it is important to remember the rules for the addition of integers numbers:
+ + Add Final result (+) - Final result (+)
- - Add Final result (-) - Final result (-)
+ - Subtract - Final result (the sign of the integer having a greater value)
- + Subtract - Final result (the sign of the integer having a greater value)
Multiplication Sign RulesThe rules for multiplication of numbers are:
+ + or - -The result presents a positive sign (+) because the signs are the same.
+ - or - +
The result presents a negative sign (-) because the signs are different.
For solving this question, you should apply the rules presented previously. And after that check, if your result is the same that the question gives.
Option1( − 6 ) 2 − ( 6 ) ( 6 ) = 36
-12 -(36) = -12 -36 = -48 -> It is not the solution given in the exercise because -48 ≠ 36.
Option2( − 6 ) ( − 2 ) =12
12=12 -> It is the solution given in the exercise because 12=12.
Option3( − 6 ) ( − 6 ) = 36
36=36-> It is the solution given in the exercise because 36=36.
Option 4( − 6 ) ( − 6 ) = − 36
36≠ -36 -> It is not the solution given in the exercise because 36 ≠ -36.

What is the expression in factored form? please show steps on how to get both answers!
1. x2+13x +42
2. 9x^2−4
^ means its number beside is the exponent.
Answers
Answer:
1. The factored form of the given expression is (x+7)(x+6).
2. What is the expression in factored form . 9x^2 -4
Step-by-step explanation:
1. The given expression is,
The degree of the expression is 2, the constant term is 42, and the coefficient of x is 13.
Use factoring by grouping method
To find the factor form, we have to find two numbers whose sum is 13 and whose product is 42.
The factors of 42 are,
From which the sum of 6 and 7 is 13.
So We can write the 13x as 7x+6x.
2. This expression can be factorized using the difference of squares which can be illustrated as follows:
A^2 - B^2 = (A+B)(A-B)
In the given example:
sqrt(9x^2) = 3x
sqrt(4) = 2
and the two squares are separated by a negative sign
Therefore, the difference of squares is applicable
Based on this, factoring the given expression would give us:
9x^2 - 4 = (3x+2)(3x-2)
