Answer:
4. 225
Step-by-step explanation:
The distance between points (-5, -3) and (-5, 12) is the length of the side of the square. Since both points have an x-coordinate of -3, they lie on the same vertical line. The distance between them is |12 - (-3)| = |12 + 3| = |15| = 15. The side measures 15 units.
area = side^2
area = 15^2 = 225
4.2 times 200 equals 840. Hope this helps
"y varies directly with square of x"
y = kx²
where "k" is the constant of variation you need to solve for first.
when y = 100 ; x = 5
100 = k(5)²
100 = 25k
100/25 = k
4 = k
Now you can solve for y when x = 9
y = 4(9)²
y = 4(81)
y = 324
