Catherine walks her dog 5.25 miles because there are 7 days in one week and 3/4 x 7 = 5.25
Answer:
i need the question
Step-by-step explanation:
Answer:
x² + 7x + 10 = 0
Subtract 10 from both sides
x² + 7x = -10
Use half the x coefficent (7/2) as the complete the square term
(x + 7/2)² = -10 + (7/2)²
note: the number added to "complete the square" is (7/2)² = 49/4
(x + 7/2)² = -10 + 49/4
(x + 7/2)² = 9/4
Take the square root of both sides
x + 7/2 = ±3/2
Subtract 7/2 from both sides
x = -7/2 ± 3/2
x = {-5, -2}
You could wash 75 cars at this rate because 45/3 equals 15. You would multiply 5 by 15 and get 75.
