Answer:
c
Step-by-step explanation:
This is a right triangle. To find the third side of a right triangle. Use the Pythagorean Theorem.
a^2+b^2=c^2
a and b are the legs, c is the hypotenuse.
a^2+7^2=16^2
a^2+49=256
Subtract 49 from both sides:
a^2=207
Square foot:
a=14.38749457 in.
Round to nearest tenth:
14.4 in
Answer:
C. 69
Step-by-step explanation:
We have,
The expression to represent the number of parking lots =
,
where x is the number of parking spots in the first row.
Now, it is given that the there are 30 parking spots in the first row.
Thus, the total number of parking lots =
= (5×15)-6 = 75-6 = 69.
Hence, the total number of parking lots is 69.

The x-intercept is -6 and the y-intercept is 2. The answer is
A.
