Answer:
x=9
Step-by-step explanation:
3x + 25 = 2(4x – 10)
3x + 25 = 8x-20
3x-8x=-20-25
-5x=-45
5x=45
x=9
A=s^2
A=25^2
A= 625ft
The area is 625ft
Answer:
Smaller x: 1.20
Larger x: 5
Step-by-step explanation:
The zeros of a function h(x) are the values of x for whom h equals zero.
So, in your problem, we have
h (x) = (-4x -5)(-x +5)
h(x) = 0 when either(-4x+5) = 0 or (-x +5) = 0. So, we solve for both cases
Case 1
-4x+5 = 0
-4x = -5 *(-1)
4x = 5
x = 5/4
x = 1.20
Case 2
-x +5 = 0
-x = -5 *(-1)
x = 5
Answer:
1/13
Step-by-step explanation:
If there are 52 cards and four aces
4/52=1/13
Meaning that the probability of you drawing an ace is 1/13
The answer is C - 400 because your are taking away 1 zero
