The first choice is correct. No, the rectangle cannot have x=60 and y=11 because x=48+2y.
Perimeter is x=2w+2y. Therefore x=2(24)+2(11) which equals 70 not 60.
29.8 would be the number, but rounded would be 30
A
substitute x = 3h into f(x)
f(3h) = 2(3h)² + 3(3h) - 4 = (2 × 9h²) + 9h - 4 = 18h² + 9h - 4
Answer:
3y
Step-by-step explanation:
The value of X is D. 25
Every triangle adds up to 180 degrees so you just add up the given numbers, then subtract that number from 180 and that is your answer.
