Answer:
If you mean Area=2 and Area=36units times 2 and Area=64units times 2, then the answer is that A = 64units times 2 would be the largest square.
Step-by-step explanation:
The larger the area, the larger the square. The first square has an area of 2. The second square has an area of 72, and the third square has an area of 128, so the third square is the biggest.
Answer: y = 6 mi. .
______________________________________________
Explanation:
______________________________________________
Area of a triangle = (½) * (base) * (height) ;
or, A = (½) * b * h ; or, A = b*h / 2 ;
_____________________________________
Given: A = 24.3 mi ² ;
b = 8.1 mi
___________________
Find the height, "h" ; (in units of "miles", or , "mi" ).
__________________________
Plug in the known values into the formula:
24.3 mi ² = (½) * (8.1 mi) *(h) ;
_____________________________
Solve for "h" (height) ;
_____________________________
(½) * (8.1 mi) = 4.05 mi ;
______________________________
Rewrite:
____________________________
24.3 mi² = (4.05 mi) *(h) ; Solve for "h" ;
_________________________________________
Divide each side of the equation by "(4.05 mi)" ; to isolate "h" on one side of the equation ; and to solve for "h" ;
__________________________________________
24.3 mi² / 4.05 mi = (4.05 mi) *(h) / 4.05 mi ;
→ 6 mi = h ; ↔ h = 6 mi.
→ h = y = 6 mi.

Answer:
Step-by-step explanation:
y = ax² + bx + c
a( - 7)² + b( - 7) + c = 134 ⇔ 49a - 7b + c = 134 ......... (1)
a( - 3)² + b( - 3) + c = 10 ⇔ 9a - 3b + c = 10 ......... (2)
a(5)² + b(5) + c = 50 ⇔ 25a + 5b + c = 50 ......... (3)
(1) - (2)
40a - 4b = 124 ⇔ 10a - b = 31 ........... (4)
(3) - (2)
16a + 8b = 40 ⇔ 2a + b = 5 ........... (5)
(4) + (5)
12a = 36 ⇒ a = 3
2(3) + b = 5 ⇒ b = - 1
9(3) - 3( - 1) + c = 10 ⇒ c = - 20
y = 3x² - x - 20
y = [ 3 ] x² + [ - 1 ] x + [ - 20 ]
