Answer:
Justin is 1 feet far away from Brandon
Step-by-step explanation:
As shown in the diagram, we let the distance between Justin and Brandon be x
from the question
the total time taken by the ball to reach Brandson=4s
Also the total distance is travelled by the ball=19+x
while the average speed=5ft/s
By substitution we obtain
x=1 feet
Mike travelled 16 + 30 = 46 miles.
To find how far Henry travelled we use the Pythagoras Theorem
x^2 = 30^2 + 16^2 = 1156
x = sqrt 1156 = 34 miles
Therefore the answer is 46 - 34 = 12 miles
Mike travelled 12 more miles than Henry.
Answer: -4x
Step-by-step explanation:
Answer:
Let x be the number
double x = 2 x
square the result (2x)^2
(2x)^2 - x subtract the original number
4 x^2 - x = 33
4 x^2 - x - 33 = 0
Solve the quadratic
(1 +- (1 + 4 * 132)^1/2) / 8
= (1 + 528^1/2) / 8 = (1 + 23) / 8 = 3 using the positive exponent
Check:
(2 * 3)^2 - 3 = 36 - 3 = 33
