Answer:
1) 
; 2) 
Step-by-step explanation:
1) Using the Power of a Fraction Rule 
,
, which can just be simplified to .
2) Using the Negative Exponent Rule, 
,
, which can be simplified to .
You use distributive property. So (5 x 2)-(5 x x)= 10 - 5x.
The property shown is a B: substitution property, this is when you you the know that X=Y so X can be substituted in any equation with Y and Y can be substituted in any equation with X. hope this helps
Answer:
The correct answer is option D. 48
Step-by-step explanation:
From the figure we can see that, some right angled triangles.
<u>To find the measure of LP</u>
Consider the right angled triangle LPT,
LT is the hypotenuse, LP = 50 units (given)
PT = QT = RT = 14 units
From figure we get,
LP² + PT² = LT²²
LP² = LT² - PT²
= 50² - 14²
= 2500 - 196
= 2304
LP =√2304
= 48
The correct answer is option D. 48
All you do is subtract 3.2 from the number 4 and you get the number -0.8
