Answer:

Transitive property of congruence.

Step-by-step explanation:

The transitive property of congruence states that if ∠A≅∠B, ∠B≅∠C then ∠A≅∠C.

For example:

x+5= 10 and 10= 5+5 then x+5= 5+5.

5 times a number is 14 less than the square of that number. Find the negative solution.
Brrunno [24]

Let x = your number.

5x = x^2 - 14. To figure out the number, we have to first subtract 5x from each side.

0 = x^2 - 5x - 14. Factor.

0 = (x - 7) (x + 2). Set both terms to 0.

(x - 7) = 0. Add 7 to each side.

x = 7. You're looking for the negative value so this isnt the right one.

Set the other term (x + 2) equal to 0

(x + 2) = 0. Subtract 2 from each side.

x = -2

The negative solution for your number is -2

Let f (x)=x-2 and g(x)=x to the second power -7x-9.find f (g(-1))
Degger [83]

f(g(-1)) = - 3

Evaluate g(-1) and substitute into f(x)

g(-1) = (-1)² -7(-1) - 9 = 1 + 7 - 9 = - 1

f(g(-1)) = (-1) - 2 = - 3

Answer:

864 ft^2

Step-by-step explanation:

Surface area equation is the same as the one used in the other problem; S=(1/2)lP + B

one side is 20 x 14 = 280

another side is 12x14 = 168

another side is 16x14 = 224

the triangle bases are A=(1/2)bh

(1/2)12 x 16 = 96

2(96) = 192

Add all sides together 192 + 224 + 280 + 168 = 864
