Dr/dt= 8cmM-¹
dA/dt = ?
but A= πr²
so dA/dr =2πr
but recall
dA/dt = dA/dr • dr/dt
dA/dt = 2πr • 8cmM-¹
dA/dt = 2×π×39 ×8 = 624cm²M-1
Since the water bill costs $35, to split it into 2 equal payments, you would simply just half $35 which is $17.50.
5x² + 5x + 2x + 2
5x(x + 1) + 2(x + 1)
(5x + 2)(x + 1)
Answer:
11,7,13
Step-by-step explanation:
coefficients come before the variable. so if it’s 13r, the variable is r. which makes the coefficient 13
