Carla is correct using a calculator to check
Answer:
t = 1 sec 5 meters
Step-by-step explanation:
When the object hits the ground , height = 0
0 = (5t+5)(1-t) so t = -1(throw out...can't have negative time value) or 1
As the object is dropped, t = 0 sub that in to the equation
h = (5(0)+5)(1-0) = 5 meters
Answer:
18
Step-by-step explanation:
Let the number be 'x'
Sum of 'x' and 12 = x +12
The product of 8 and the sum of a number and 12 = 8* (x +12)
= 8*x + 8*12
= 8x + 96
8x + 96 = 240
Subtract 96 from both sides
8x + 9 6 - 96 = 240 - 96
8x = 144
Divide both sides by 8
x = 144/8
x = 18
