21,500 this is the answer
Answer:
Step-by-step explanation:
Take the negative exponent in the denominator to make it positive
Example = (2^-3)
= 1/2³
A) The dimensions are (x+10) by (x+10).
B) The perimeter is given by 4x+40.
C) The perimeter when x is 4 is 56.
The quadratic can be factored by finding factors of c, the constant, that sum to b, the coefficient of x. Our c is 100 and our b is 20; we want factors of 100 that sum to 20. 10*10=100 and 10+10=20, so those are what we need. This gives us (x+10)(x+10 for the factored form.
Since the dimensions are all (x+10), and there are 4 sides, the perimeter is given by 4(x+10). Using the distributive property we have 4*x+4*10=4x+40.
To find the perimeter when x=4, substitute 4 into our perimeter expression:
4*4+40=16+40=56.
You need to divide 320000 by 2 since the speed was divided by 2. The final answer is ...... 160000 Joules.
I hope this helped!!!! :D
