3(x+8)
You know that area of a rectangle is length x width. The width you know is 3 and the length is whatever x is plus 8 more inches, therefore it is x+8.
To solve these types of problems, we need to convert the two values into the same form.
We know that 1 = 1.00, as adding zeroes to the end of a decimal doesn't change the value.
To change a decimal into a percentage, we multiply the decimal by 100 and add a percent sign.
1.00 * 100 = 100%
Therefore, 1 = 100%
Because 120% is greater than 100%, thus,
120% > 1
A) n(a) = 25 + 15 = 40
b) n(b) = 42+15 =57
c) n (a U b) = 25 +15+ 42 = 82
d) n (a') = 42
e) n(b') = 25
f) n(a intersection b)' = 82-15 = 67
g) n (a U b)' = 14
h) n (a' intersection b') = 14
i) n (a' U b') = 42 + 25 +14 = 81
hope i helped a bit .. :-)
Answer:
Divide by 7 on both sides
Step-by-step explanation:
7x = 28
To get the variable (x), alone we must divide by 7 on both sides
Value of x: x = 4
Hope this helps :)
It is 1,01000 is the answer
