The answer would be B) 6x + 2.
5x + 2 + x (simplify)
(5x + x) + 2 (gather like terms)
6x + 2 (simplify).
Answer:
4
Step-by-step explanation:
We'll do two things here. First remember that when a number is raised to an exponent, and the result is raised to another exponent, you can simply multiply those exponents and apply them to the base. So we can multiply -1/2 and -2/3, giving us 1/3, which is what we'll raise 64 to.
The other thing to remember is that a fractional exponent is the same as a root of that base. So raising a number to the power of 1/3 just means we want the cube root of that number.
Applying those and we get:
Below is a scale drawing of the town swimming pool. In the drawing, the longest side of the
pool has a length of 10 inches. Paco creates a new scale drawing of the pool. In his drawing,
the longest side of the pool has a length of 5 inches. What scale is Paco's new drawing?
If there are 1,400,000 drops in 25 gallons:
1 drop = 25 gallons : 1,400,000 = 0.0000178 gallons
It is 0.00178 % of a gallon.
Use Pythagorem theorem (Sorry I can't spell)
but use one variable (a) since a and b are same
60=a^2+a^2
60=2a^2
30=a^2
a=square root of 30
a= 5.48 (round to nearest 100)
since a and b are same, they are 5.48
note that a^2 means a to the power of 2
