60x+80=100x combine like terms
80=100x-60x or 40x divide to get x by itself
80/40=40x/40
20=x
after 20 hrs
Answer:
h(x) = −183
Step-by-step explanation:
h(x) = -5x² - x + 3 , h(6)
Replace the variable x with 6 in the expression.
h(6) = − 5(6)² −(6) + 3
−5 ⋅ 36 −(6) + 3
−180 − 6 + 3
−186 + 3
−183

Hey there :)
Let us change the sentence into mathematics:
Area of rectangle = 35 m²
Length of rectangle is 3 m more than twice the width = 3 + 3w
Width = w
We know the area formula of a rectangle
Area = length × width
Dimensions of the rectangle are:
35 = w ( 3 + 2w )
35 = 3w + 2w²
Take all values to one side and equate to 0
2w² + 3w - 35 = 0
Factor:
( 2w - 7 ) ( w + 5 ) = 0
w =
or w = - 5 ( Reject because lengths can never be negative )
Therefore the dimensions are:
Width = 3.5 mLength = 3 + 2 ( 3.5 ) = 10 m
