keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above
so then we can say that
so we're really looking for the equation of a line whos slope is 9/2 and passes through (2 , 3)
now as far as the parallel line
keeping in mind that parallel lines have exactly the same slope, so we're really looking for the equation of a line whose slope is -2/9 and passes through (2 , 3)
So, all we have to do here is multiply:
First, the amount of car spaces by the amount of rows:
38 x 4 = 152
This is the number of parking spots per level.
Then, the number of levels by the number of parking spots on each level:
152 x 7 = 1064
So, a total of 1,064 cars can be parked in this building!
Answer:
length = 25 feet and width = 17 feet
Step-by-step explanation:
area (A ) = length × width, hence
A = (x + 10)(x + 2) ← expand factors
= x² + 12x + 20
given A = 425, then
x² + 12x + 20 = 425 ( subtract 425 from both sides )
x² + 12x - 405 = 0 ← in standard form
(x + 27)(x - 15) = 0 ← in factored form
equate each factor to zero and solve for x
x + 27 = 0 ⇒ x = - 27
x - 15 = 0 ⇒ x = 15
but x > 0 ⇒ x = 15, therefore
length = 15 + 10 = 25 feet and width = 15 + 2 = 17 feet
I had a problem like this but it was different but what i divided was 216 divided by 12 and got 18 and 216 divided by 6 and got 36
Answer:
x = 80°
Step-by-step explanation:
x is the measure of a central angle which is equal to the measure of the intercepted arc.
So, x = 80°
