Answer:
0.04
Step-by-step explanation:
Using absolute value |.02|+|.-02|= .04
$97.2
120*.75 =90 (discounted price)
90*.08 = 7.2 (amount sales tax)
90 + 7.2= 97.2
Answer: the x-intercept would be (2,-2)
Step-by-step explanation:
The width of the pathway is 3m
Step-by-step explanation:
Let the width of the pathway be 'w'
The area will be 130 square meters
The dimensions of the garden is 10 x 7
Area = (10+w) (7+w)
130 = 70 + 17w + w^2
w^2 + 17w - 60 = 0
w^2 +20w - 3w - 60 = 0
w ( w + 20) - 3 ( w + 20) = 0
(w + 20) (w - 3) = 0
w = -20 ( or) w = 3
w is the width and cannot be negative.
So, w = 3 meters
The width of the pathway is 3m
