Note: a² - b² = (a-b)(a+b)
9x² - 16y² = (3x)² - (4y)² = (3x - 4y)(3x + 4y)
It’s -10
Explanation: 8 x 5= 40
40/-4= -10
Answer:
$40
Step-by-step explanation:
If he spent $40 and has none left that means he currently has $0.
If you subtract $40 - b = $0
b = $40

Answer:
Step-by-step explanation:
velocity of turtle = 5 feet / min
velocity of snail = - 11 feet / min
By using the formula of relative velcoity
the velocity of turtle with respect to snail is
V' = velocity of turtle - velocity of snail
V' = 5 - (- 11)
V' = 16 feet / min
