Answer: 9
explanation:
4+(-7)= -3
next, you multiply -3 and -3 which is 9 as the two negatives cancel out
The answer is 90
10% 25
30% 75%
1% 2.5
8% 20
75+ 20= 90
Answer:
x = 2 or x = 1 or x = 0 or x = -1 or x = -2
Step-by-step explanation:
Solve for x:
x^5 - 5 x^3 + 4 x = 0
The left hand side factors into a product with five terms:
x (x - 2) (x - 1) (x + 1) (x + 2) = 0
Split into five equations:
x - 2 = 0 or x - 1 = 0 or x = 0 or x + 1 = 0 or x + 2 = 0
Add 2 to both sides:
x = 2 or x - 1 = 0 or x = 0 or x + 1 = 0 or x + 2 = 0
Add 1 to both sides:
x = 2 or x = 1 or x = 0 or x + 1 = 0 or x + 2 = 0
Subtract 1 from both sides:
x = 2 or x = 1 or x = 0 or x = -1 or x + 2 = 0
Subtract 2 from both sides:
Answer: x = 2 or x = 1 or x = 0 or x = -1 or x = -2
<h3>Answer:</h3>
Option B: 63
<h2>Given that:</h2>
The given function is 
<h2>Explanation:</h2>
To evaluate the value of a function at given value of input, you should replace the variable given in the function with the value of input that is given, in your case it is x = 5.
For x = 5, we have
Similarly, you will be able to evaluate the value of the function for any other input given, which is assumed to be valid.
Hence option b: 63 is the correct option.

Answer:
D
Step-by-step explanation:
Since triangles ABC and CDB are similar, CD and CB is the same as the ratio between CB and CA. 15:9=x:15. x=25. Subtracting CD to just be left with AD, we get 25-9=16, or answer choice D. Hope this helps!
