A positive number is multiplied by itself and then 7 is added. The answer is 16. What is the number?

Alika [10]

Answer:

Step-by-step explanation:

let the number be n then multiplied by itself gives n², thus

n² + 7 = 16 ( subtract 7 from both sides )

n² = 9 ( take the square root of both sides )

n = $\sqrt{9}$ = 3

Which products result in a difference of squares? Check all that apply.

sleet_krkn [62]

Answers
1. (3 + xz)(–3 + xz)
2. (y² – xy)(y² + xy)
3. (64y2 + x2)(–x2 + 64y2)

Explanation
The difference of 2 squares is in the form (a+b)(a-c).
(3 + xz)(–3 + xz) = (3 + xz)(xz -3)
= (xz + 3)(xz - 3)
= x²y²-3xy+3xy-9
 =x²y² - 3²

(y² – xy)(y² + xy) = y⁴+xy³-xy³-x²y²
 = y⁴ - x²y²


(64y2 + x2)(–x2 + 64y2)= (64y²+x²)(64y²-x²)
= 4096y⁴-64y²x²+64y²x²-x⁴
= 4096y⁴ - x⁴
