Answer:
Divide by 4, because 4 is a factor of 88.
Step-by-step explanation:
This is incorrect reasoning because what the constant is on the right side of the equation has nothing to do with the number you are dividing by. In other words, you are dividing by 4 because that isolates the x-variable, and if it was 5x you would divide by 5. The number that you are dividing by only is determined by what number isolates x.
Answer:
Vertex: (5, -9)
Step-by-step explanation:
fix = (x-8)(x-2)
fix = x^2 - 2x - 8x + 16
fix = x^2 - 10x + 16
a = 1, b = -10, and c = 16
To find vertex:
x = -b/2a
x = -(-10)/2(1)
x = 10/2
x = 5
y = 5^2 - 10(5) + 16
y = 25 -50 + 16
y = -9
Vertex: (5, -9)
Let c be the hypotenuse in miles.
72 + 92 = c2
49 + 81 = c2
130 = c2
130‾‾‾‾√ = 2‾‾√
130‾‾‾‾√ = c
11.4 ≈ c
The path along Riverside Drive is shorter, about 11.4miles, compared to the path along Cypress and Control Avenues, 16 miles. The difference is about 4.6 miles. The Pythagorean theorem allowed me to calculate the distance along Riverside Drive because the three roads from a right triangle.
The formula I like to use is
A = 2(LW + H(L+W))
For your dimensions, this is
A = 2((5 cm)(5 cm) + (12 cm)(5 cm + 5 cm))
A = 2(25 cm² + 120 cm²)
A = 290 cm²
The surface area of your right rectangular prism is 290 cm².
