(7)^2-4(5)(-6)=
49+120=169 is the answer
The answer is 1.6
How I figured it out:
I divided 8 by 5, which gave me 1.6
To make sure this was right, I multiplied 1.6 by 5, which gave me an answer of 8 or other known as 8 inches.
In conclusion, the number of inces per hour is 1.6

Answer:
A
Step-by-step explanation:
One Solution
Answer:
Answer 1; Angles forming a linear sum to 180°
Answer 2; Substitution
Answer 3; Definition of perpendicular lines
Step-by-step explanation:
The two column proof is presented as follows;
Statement
Reason
1. ∠SWT ≅ ∠TWU
Given
2. m∠SWT + m∠TWU = 180°
Angles forming a linear sum to 180°
3. m∠SWT + m∠SWT = 180°
Substitution
4. m∠SWT = 90°
Algebra
5.
⊥
Definition of perpendicular lines
Perpendicular lines are defined as lines that are at right angles (90°) to each other, therefore given that the angle formed by the lines
and
m∠SWT = 90°, therefore, the lines
and
are perpendicular to each other.
