Let's solve ~

$\qquad \looparrowright \sf - 7 \sqrt{80 {x}^{4} y {}^{2} }$

$\qquad \looparrowright \sf - 7 \sqrt{2 {}^{4} \times 5 \times {x}^{4} \times {y}^{2} }$

$\qquad \looparrowright \sf - 7 \times {2}^{2} \times {x}^{2} \times y \times \sqrt{5}$

$\qquad \looparrowright \sf - 28 {x}^{2} y \sqrt{5}$

Therefore, Option D is correct ~

Pleeeease help me translate the following sentence into an equation using n to represent the unknown number. Then solve the equa

anygoal [31]

Six more than: 6 + or + 6
twice a number: let n represent the unknown number: 2n

6 + 2n = 16

So, the answer is either c or d

So, solve the equation

Subtract 6 on both sides of the equation

2n=10

Divide by 2 on both sides of the equation

n=5

So, the answer is C
