2x^2-7x-18x+63
2x^2-25x+63
Answer:
1133.54 in.^2
Step-by-step explanation:
The answer is the area of the circle which is in white inside the square. We are not looking for the shaded area.
A = (pi)r^2
r = d/2 = 38 in./2 = 19 in.
A = (3.14)(19 in.)^2
A = (3.14)(19 in.)(19 in.)
A = 1133.54 in.^2
Answer:
You would divide.
Step-by-step explanation:
$851÷ $23= 37
Use the Pythagorean theorem
let = length of ram = l
l² = 4² 18²
l² = 16 + 324
l² = 340
l = 18.4390889146
l = 18.4 ft.
A(5,8) and B(x ,y)
m = (y₂ - y₁)/(x₂-x₁)
m = (y-8)/(x-5)
m = 0 if and only if y = 8
The equation becomes:
y = 0.x + b
8 = 0.x +b → y = 8 (line // to x-axis at y=8)
