Answer:
surface area≈126.65
Step-by-step explanation:
A=2AB+(a+b+c)h
AB=s(s﹣a)(s﹣b)(s﹣c)
s=a+b+c
2
Solving forA
A=ah+bh+ch+1
2﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=5·7+5·7+5·7+1
2·﹣54+2·(5·5)2+2·(5·5)2﹣54+2·(5·5)2﹣54≈126.65064
Answer:
Percentage Calculator: What is the percentage increase/decrease from 6000 to 600? = -90.
Step-by-step explanation:
Have you tried sketching this situation?
x is the length of the side of his original office. If he adds 15 ft, then the area, A, would be x times (x+15). 15x represents the floor area of the addition.
The value of x in the simplified power is 20.
Solution:
Given expression:
Step 1: Express 4 factors of
Step 2: Expand the expression
Step 3: Simplify to the exponential form
There four -2 terms and four terms.
Step 4: Evaluate the base 2 power.
Step 5: Apply the power of a power.
Using exponent rule:
So that
⇒ x = 20
The value of x in the simplified power is 20.
