Find the value of x.

Answers

Answer:

110 degrees

Step-by-step explanation:

The sum of all the interior angles of a polygon is always equal to 180(n-2) where n is the number of sides. In this figure, there are 7 sides. This means that the sum of all the interior angles is 180(7-2) = 180 * 5 = 900.

Now, add up all the angles that you know and subtract that from 900 to find the value of x.

900 - (105 + 150 + 140 + 135 + 125 + 135) = 900 - 790 = 110 degrees

110 degrees ^^^^^^^^^

Solve by using the perfect squares method.x2 + 16x + 64= 0
a. –8
b. –16
c. 8
d. 16

Answers

x² + 16x + 64 = 0
x² + 2 * x * 8 + 8² = 0

Now, sing the formula (a + b)² = a² + 2ab + b² , we get,

(x + 8)² = 0

Square rooting on both sides, we get,

x + 8 = √0

x + 8 = 0

x = - 8 <== that's your answer!!!

x²+16x+64=(x+8)² (because (a+b)²=a²+2ab+b² => perfect square)
So you have to find x which will make (x+8)²=0
which is true when x+8=0
x=-8
That's a.

If F (x) = 5x^3 - 2 and g (x) = x+1, find (f-g) (x)

Answers

(f-g)(x) is in fact f(x) - g(x):

f(x) - g(x)

= 5x³ - 2 - ( x + 1 )

= 5x³ - 2 - x - 1

= 5x³ - x - 3

the distance between vancouver and winnipeg is 1850 km in a straight line. the distance on a map is 3.7 cm. write a scale statement for the map. what is the scale factor used to make the map?

Answers

Given:
1850 km
3.7 cm

1 km = 100,000 cm
1850 km * 100,000cm/1km = 1850 * 100,000 cm = 185,000,000 cm

scale statement: 3.7cm on the map represents 1850 km of actual distance between Vancouver and Winnipeg.

Scale factor used 3.7 cm : 185,000,000 cm or 1 : 50,000,000

185,000,000 cm ÷ 3.7 cm = 50,000,000
