Step-by-step explanation:
Answer:
B. -1.75 and 4
Step-by-step explanation:
f(x)=g(x)
Input the equations
x²-2x-8 = 1/4x-1
add 1 to both sides
and subtract 1/4x from both sides
x²-2 1/4x - 7 = 0
factor
a + b = -2 1/4
a * b = -7
1.75 + -4 = -2 1/4
1.75 * -4 = -7
reverse their symbols
1.75 becomes -1.75 and -4 becomes 4.
Answer:
7x21
Step-by-step explanation:
First, we need to find the length of the pool. Since it is three times as long as it is wide, it is 21 feet long (7 x 3 = 21). That way we can tell that it is 7x21, with a perimeter of 56 feet, and an area of 147 feet squared.
