Answer:

The area of the regular octagon is 293.72\ units^{2}

Step-by-step explanation:

we know that

The area of the regular polygon is equal to

A=\frac{1}{2}Pa

where

P is the perimeter of the regular polygon

a is the apothem

<em>Find the perimeter P</em>

P=8(7)=56\ units

Find the area

A=\frac{1}{2}(56)(10.49)=293.72\ units^{2}

Subtract 3 from both sides:

7x = -77

Divide both sides by 7:

x = -11

The number is -11

SSSSS [86.1K]

Answer:

y=-5x-36

Step-by-step explanation:

-66-(-61)= -5

6-5= 1

-5/1= -5

Y=-5x + B

-66= -5(6) + B

-66= -30 + B

-66 + 30 = (-30 +30) + B

-36 = B

Y= -5x-36

If 4 : 9 is equivalent to (5x+13) : 63, then what is the value of x?
Aleksandr [31]

\large{\underline{\underline{\pmb{\sf{\color{yellow}{Answer:}}}}}}

The value of x is 3

Step-by-step explanation:

\textsf{\underline{\large{To find :-}}}

The value of x

\textsf{\underline{\large{Given :-}}}

4 : 9 = (5x + 13) : 63

\textsf{\underline{\underline{\large{Solution :-}}}}

we can write this as

\sf \frac{4}{9}  =  \frac{(5x + 13)}{63}

Now we will cross multiply the values

\sf 4 \times 63 = 9(5x + 13) \\  \\  \sf  252 = 45x + 117 \\  \\  \sf 252 - 117 = 45x \\  \\  \sf 135 = 45x \\  \\  \sf  \frac{135}{45}  = x \\  \\  \sf  \orange {3 = x}
