Answer:
4, -3
Step-by-step explanation:
The quadratic formula is 
.
When using the formula for both the negative and positive value of the sqrt, you will get:
x = 4, -3
The answer is √91 feet (which is the same as 9.54 feet).
Imagine this as a right triangle. A length of the foot is actually a hypotenuse (c). The distance from wall's base to the ladder foot is one of the sides of the triangle (let it be a).
So, using the Pythagorean theorem:
c² = a² + b²
It is given:
c = 10 feet
a = 3 feet
b = ?
c² = a² + b²
⇒ 10² = 3² + b²
100 = 9 + b²
b² = 100 - 9 = 91
⇒ b = √b² = √91 ≈ 9.54 feet
Answer:
they are alike because they both include a variable and they both have their totals in currency form. They are different because they use different variables.
