5 + 2² - 3(6) ÷ 3
= 5 + 2² - 18 ÷ 3 
= 5 + 4 - 18 ÷ 3
= 5 + 4 - 6
= 3

-(3² -12) + 4 ÷ 2
= -3² + 12 + 4 ÷ 2
= -9 + 12 + 4 ÷ 2
= -9 + 12 + 2
= 5

7 × 2² ÷ 4 + 12
= 7 × 4 ÷ 4 + 12
= 7 × 1 + 12
= 7 + 12
= 19

6² + 4 - 3
= 36 + 4 - 3
= 40 - 3
= 37

Equation of a line that is perpendicular to given line is y=\frac{-7}{4} x+\frac{7}{4}.

Equation of a line that is parallel to given line is y=\frac{4}{7} x-\frac{69}{7}.

Solution:

Given line y=\frac{4}{7} x+4.

Slope of this line, m_1 = \frac{4}{7}

$\text{Slope of perpendicular line} = \frac{-1}{\text{Slope of the given line} }

                                   $m_2=\frac{-1}{m_1}

                                          $=\frac{-1}{\frac{4}{7} }

Slope of perpendicular line, m_2=\frac{-7}{4}

Passes through the point (–7, 5). Here x_1=-7, y_1=5.

Point-slope formula:

y-y_1=m(x-x_1)

$y-(-7)=\frac{-7}{4} (x-5)

$y+7=\frac{-7}{4} x+\frac{35}{4}

Subtract 7 from both sides, we get

$y=\frac{-7}{4} x+\frac{7}{4}

Equation of a line that is perpendicular to given line is y=\frac{-7}{4} x+\frac{7}{4}.

To find the parallel line:

Slopes of parallel lines are equal.

m_1=m_3

$m_3=\frac{4}{7}

Passes through the point (–7, 5). Here x_1=-7, y_1=5.

Point-slope formula:

$y-(-7)=\frac{4}{7} (x-5)

$y+7=\frac{4}{7} x-\frac{20}{7}

Subtract 7 from both sides,

$y=\frac{4}{7} x-\frac{69}{7}

Equation of a line that is parallel to given line is y=\frac{4}{7} x-\frac{69}{7}.

Answer:

circle question: 69.66

the other question: 66.8

Step-by-step explanation:

For the circle question:

the circle is inscribed in the square, so the diameter of the circle = side of the square

so we need to find the area of square and circle

then do this

square area - circle area

square area(side×side) = 324

circle area(pi×r^2)≈254.469

so shaded region = 69.66

__________

the other question:

we need to find the area of triangle and the area of the rectangle and add them together

A of Triangle (1/2×base×hight) = 34.32

A of rectangle (width × length) = 31.92

add them, so the answer will be = 66.8
