Answer:
Step-by-step explanation:
(x-3)/2 = 9
x - 3 = 18
x = 21
(y-5)/2= 6
y - 5 = 12
y = 17
(21, 17)
Answer:
$80
Step-by-step explanation:
Area of Mr Jones's yard = 40 * 65 square feet
= 2600 square feet
Mr. Jones was charged $52 for the yard.
Therefore cost per square feet = 52/2600 = $0.02 per square feet
Area of neighbor's yard = 50 * 80 = 4000 square feet
Hence the neighbor will be charged 0.02 * 4000 = $80
For the area corresponding to the yard of size 4000 square feet, he will have to pay $80 to the landscaping company.
Answer:
a = 50°, b = 130°, c = 20°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles in the right triangle
a + 40° + 90° = 180°
a + 130° = 180° ( subtract 130° from both sides )
a = 50°
a and b are adjacent angles and sum to 180° , so
a + b = 180°
50° + b = 180° ( subtract 50° from both sides )
b = 130°
Then sum the angles in the top triangle, that is
30° + 130° + c = 180°
160° + c = 180° ( subtract 160° from both sides )
c = 20°
Answer:f '(x) = 2(3x2 + 5) + 6x(2x - 1)
= 6x2 + 10 + 12x2 - 6x
= 18x2 - 6x + 10
