The area of the fence is 6*25=150 square feet.
It will take him 150 / 2 = 75 of 10-minute intervals. 75 min *10 = 750 min = 750/60 hours = 12.5 hours.
It would be y= -2/5x+4 since perpendicular lines have a gradient that is the negative reciprocal of the original. in thw pictire is the formula method
Answer:
y = -12
Explanation:
−7(2y + 12) − 6y = 156
Simplify both sides of the equation
−7(2y + 12) − 6y = 156
(−7)(2y) + (−7)(12) + −6y = 156 (Distribute)
−14y + −84 + −6y = 156
(−14y + −6y) + (−84) = 156 (Combine Like Terms)
−20y + −84 = 156
−20y − 84 = 156
Add 84 to both sides
−20y − 84 + 84 = 156 + 84
−20y = 240
Divide both sides by -20
-20y / -20 = 240 / -20
y = -12
So first thing you do is :
c^1/2*d^1/2*d^1/3
then you find sum of the exponents for d
c^1/2*d^(1/2+1/3)
c^1/2*d^5/6
then first number goes under the root, second number outside
so you have root from c ( you do not write number 1 as an exponent and 2 in front of the root because it's already considered to be a square root. As for the d:
6 sqrt(d^5)
