Not sure at all but i think it could be B.
If you multiply (x^2 - 5) by (x^2 + 5) then you get (x^4 - 25)
Answer:
18/36 in simplest form is 1/2.
1 5/8 to an improper fraction is 13/8
19/5 to mixed fraction is 3 4/5 in simplest form
Step-by-step explanation:
18 and 36 in share a common denominator of 18. 18 divided on 18 is 1. 36 divided on 18 is 2. so 1/2 is equivalent to 18/36.
1 5/8 equals one whole (8) plus 5. 8 + 5= 13. 13/5 is your answer
19 divided on 5 is 3.8. 3.8 converted to a fraction is 3 and 0.75. 0.75 in fraction form is 4/5. your answer is 19/5 = 3 4/5 or 3 and 8/10.

Answer:
H
Step-by-step explanation:
Let a represent Ann's height, and let j represent Jay's height
Break up the sentence into the key parts.
"The difference between Ann's and Jay's heights" "is" "half of Jay's height"
"The difference between Ann's and Jay's heights" becomes the expression:
a - j
"is" is math means an equal sign '='
"half of Jay's height" becomes the expression: (1/2)j
Put the 3 parts together and get the equation:
a - j = (1/2)j,
Since all the equations in the answer choices are in terms of a, solve the above equation for a...
a = (1/2)j + j, which is answer H

Answer: 117.45 ft²
Step-by-step explanation:
There is a general formula for calculate the surface area of a regular pyramid. This is:
Where p is the perimeter of the base, l is the slant height and B is the area of the base.
The perimeter is:
The base is an hexagon, therefore you can find the area by using the formula for the area of a regular polygon:
The slant height can be calculated with Pythagorean theorem. The hypotenuse is the slant height and the other legs are 6ft and:
Then:
Then, the surface area is:
