Answer:

Simplify both sides of the equation to get a^2 + 2ab + b^2 - c^2 = 2ab. Then subtract 2ab and add c^2 to both sides of the equation

Step-by-step explanation:

(a+b)^2 - c^2 = 4(1/2 ab)

Simplify both sides

a^2 + 2ab + b^2 - c^2 = 2ab

Subtract 2ab and add c^2 to both sides

a^2 + 2ab + b^2 - c^2 - 2ab + c^2 = 2ab - 2ab + c^2

a^2 + b^2 = c^2

Answer is the second option

Simplify both sides of the equation to get a^2 + 2ab + b^2 - c^2 = 2ab. Then subtract 2ab and add c^2 to both sides of the equation

Melanie's room measures 10 ft by 12 ft. Her rug covers 90 ft². Explain how to determine the percent of floor covered by the rug.

Inessa [10]

$\huge \bf༆ Answer ༄$

Here's the solution ~

Area of floor is ;

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:10 \times 12$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:120 \: ft {}^{2}$

Area covered by rug is ;

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:90 \: ft {}^{2}$

So, the percentage of floor covered by rug is ~

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \: \dfrac{90}{120} \times 100$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \: \dfrac{3}{4} \times 100$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:3 \times 25$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:75 \%$

const2013 [10]

Answer:

HCF = 33.

Step-by-step explanation:

99 = 3*3*11

165 = 3*5*11

3 and 11 are common so the HCF = 3*11

= 33.
