Answer:

Perimeter: 48\sqrt{2} \: \mathrm{inches}

Area: 288\mathrm \: \mathrm{square \: inches}

Step-by-step explanation:

If the diagonal of the square is 24 inches, the side length of the square is 12\sqrt{2} inches (2x^2=24^2). The perimeter of this square is then 4 \cdot 12\sqrt{2}=\fbox{$48\sqrt{2}\: \mathrm{in}$} and the area (12\sqrt{2})^2=\fbox{$288\: \mathrm{in^2}$}.

1. F(3)= -2(3)-5

-6-5

F(3)=-11

2. F(3)= -2(3)^2-4

-6^2-4

36-4

F(3)=32

3. F(x)=−2x−5

For: x=−2, f(x) is:f(−2)=(−2×−2)−5=4−5=−1

For: x=−1, f(x) is:f(−1)=(−2×−1)−5=2−5=−3

For: x=1, f(x) is:f(1)=(−2×1)−5=−2−5=−7

For: x=2, f(x) is:f(2)=(−2×2)−5=−4−5=−9

The Range is:

{−1,−3,−7,−9}

4. -80, -110

36= 12.5% because 25%+62.5%= 87.5%

So 100%-87.5%=12.5%

87.5%-12.5%= 75%

36+36=72=25%

72+72+72+72= 288 = 100%

So the total number of pages in the magazine is 288

I could not see the first question so i couldn't answer.

2) Draw a horizontal line and cut it in half with a vertical angle. 4 equal quarters will form. There each quarter is 90° (right angle is exactly 90°angle)

3) Just add the two angles.

x =13+19

x= 32° (Answer)

4) We must know the other angle value in order to find x. So considering both the angles are equal,

2x = 44

x= 22° (Answer)

5) Yes, x = 80° because the line cutted is a straight line and the value of a straight line is 180°

6) Supplementary angles total 180°

Complementary angles total 90°

7)Opposite angles is equal when two straight lines intersect. So,

14x - 16 = 12x + 22

14x-12x=22+16

2x= 38

x= 19° (Answer)

8) Corresponding angles

9) 140°
