Answer:

Step-by-step explanation:

Area of a square =

$s^2$

Perimeter =

$4\times s$

Where s = side

Solve for s using the area

$A =49\\\\49 = s^2\\\\Square\:root \:both\:sides\:of\:the\:equation\\\\\sqrt{49} = \sqrt{s^2} \\\\7 =s\\\\s =7$

Find the perimeter

$4\times s\\\\= 4 \times 7\\\\= 28$

katen-ka-za [31]

X - the percent increase

$25+25x=35 \ \ \ |-25 \\
25x=10 \ \ \ |\div 25 \\
x=\frac{10}{25} \\
\Downarrow \\
x=\frac{10}{25}=\frac{10 \times 4}{25 \times 4}=\frac{40}{100}=40\%$

Amanda [17]

Answer:

12 = -15

Step-by-step explanation:

Remember PEMDAS

Parenthesis

Exponents

Multiplication and Division (Left to Right)

Addition and Subtraction (Left to right)

4+ [8 = (8 - 7) + 6 - 12] - 10

4+ [8 = (8 - 7) + 6 - 12] - 10

4+ [8 = 1 + 6 - 12] - 10

4+ [8 = 1 + 6 - 12] - 10

4+ [8 = -5] - 10

4 + 8 = -5 - 10

4 + 8 = -15

12 = -15
