Answer:
x = 5
Step-by-step explanation:
x² + (2x+2)² = (2x+3)²
x² + 4x² + 8x + 4 = 4x² + 12x + 9
x² - 4x - 5 = 0
(x - 5)(x + 1) = 0
x = -1 This can be discounted as the answer because you cannot have a negative length
answer: x = 5
Answer:
$341.96
Step-by-step explanation:
Assuming Kerry was not paid at an overtime rate for extra hours (despite his union affiliation), his gross pay is ...
(46 h)×($9.60/h) = $441.60
His percentage deductions add to 17.65%, so will have a dollar amount of ...
0.1765×$441.60 = $77.94
The dollar amount deductions total $21.70 in addition to his percentage deductions, so Kerry's net pay is ...
$441.60 -77.94 -21.70 = $341.96
The mathematical sentance would be, 740 - 14 = 726, hope this helps.:D
Length of train : 100
length of bridge : 400
distance covered by the train to cross the bridge : (100 + 400) = 500
time taken by the train to cross : 30
speed = distance / time
speed = 500/30
speed = 16.67 meters per second <===
W=A\L
Divide L from both sides
The L in the right cancels out
