Answer:
The base is 8 ft and the height is 6 ft.
Step-by-step explanation:
If the height of the triangle is x feet its base = 2x - 4 feet.
So the area of the triangle
= 1/2 * base * height
= 1/2 * (2x - 4) * x = 24
(x - 2) * x = 24
x^2 - 2x - 24 = 0
(x - 6)(x + 4) = 0
x = 6, -4 As x is the height it must be 6 feet.
The base = 2x - 4 = 2(6) - 4 = 8 feet.
1 all real numbers
2 no solution
3 x=0
I believe the answer is D. let me know if im wrong
Answer:
See answers below :)
Step-by-step explanation:
-2(2 - 5) + 10 + (-5) =
-2(-3) + 10 - 5 =
6 + 10 - 5 =
11
8 - 2(9 - 5)^2 - 1 =
8 - 2(4)^2 - 1 =
8 - 2(16) - 1 =
8 - 32 - 1 =
-25
