Part A: Yes, Triangle DEF and DBC are the same triangle, but DBC is smaller than DEF because it is just a cut off of DEF.

Part B: I am pretty sure it is angle C.

Part C: I am pretty sure it is angle D.

Answer:

Step-by-step explanation:

Part A.

m < B = m < E (corresponding angles, (BC parallel to EF))

m < C = m < F ( as above)

So triangles DBC and DEF are similar ( by 2 equal angles).

Part B.

Line segment BC ( as they are both opposite < D)

Part C.

< C as its in same relative position to < F.

If f(x)=3^x-1 + 4 and g(x)=4x-7 what is (f-g)(x)?

gregori [183]

$f(x)=3^{x-1}+4\\\\g(x)=4x-7\\\\(f-g)(x)=3^{x-1}+4-(4x-7)=3^{x-1}+4-4x+7=3^{x-1}-4x+11$

The perimeter of a pool table is 30 feet. The table is twice as long as it is wide. What is the length of the pool table?

olga55 [171]

So, 30 is the perimeter. We are told the table is twice as long as it is wide.

So, we have think of 2 numbers, one being twice as big than the other. So, it is a rectangle The two number represents the length and the width. To find the perimeter we add all the lengths and the widths. Since the pool table is a rectangle we have two lengths and two widths.

So,

the tow numbers be 10 and 5. 5 is half of 10 and, when multiplied by 2 it is 10. So just to make sure the numbers 5 and 10 work out lets do a calculation.

So,

10+5+10+5 = 30feet. This proves that the sides are these two numbers.
