Answer:
Some of the Exponents = -2 that is true, not 2.
Step-by-step explanation:
Let's check one at a time.
(a)The 6 without an exponent is equivalent to the 6 having a 0 exponent.
and 
= 6 (no exponent. 6 
1 therefore this statement is False.
(b)The sum of the exponents is -2.
let's check , if the base is same we can add the exponents that is the exponent rule.(well established).
if we add exponents in the given expression we get.
, therefore we can see that the sum of the exponents = -2 this is true.
(c) An equivalent expression is 65.6-7, lets evaluate our above expression, it is equal to 
which we can see that 
,therefore this statement is false as well.
Answer:
Volume = 202.5 cubic feet
Step-by-step explanation:
Given that the aquarium is in the shape of a right rectangular prism in which
Length L = 6 1/4 feet
Width W = 7 1/5 feet
Height H = 4 1/2 feet
Volume = L × B × H
Volume = 25/4 × 36/5 × 9/2
Volume = 5 × 9 × 4.5
Volume = 202.5 cubic feet
<span>The correct answer is 11 ft.
Explanation:
The diagonals of a parallelogram bisect each other. This means that the portion marked x+4 is the same length as the portion marked 2x-7; this gives us the equation x+4=2x-7.
Subtract x from each side:
x+4-x=2x-7-x
4=x-7.
Add 7 to both sides:
4+7=x-7+7
11=x</span>
the answer is multiply the current term by 2 and add 1 to find the next term.
