Answer:

- 22

Step-by-step explanation:

let the number be n then 2(n + 9) is the sum of the number and nine doubled, thus

2(n + 9) = n - 4 ← 4 less than the number

Distribute parenthesis

2n + 18 = n - 4 ( subtract n from both sides )

n + 18 = - 4 ( subtract 18 from both sides )

n = - 22

The number is - 22

In the table, you can see level 1 is 5 to the first power, level 2 is 5 to the second and go on. 
so in level 6 would be 5 to the sixth power
so the answer to first one is 5^6 
for the second question you should know that level 2 is 5^2 and level 6 is 5^6 so 5^6/5^2 = 5^4 is the answer :))))
I hope this is helpful
have a nice day

How can ΔABC be mapped to ΔXYZ?
Arturiano [62]

Answer:

Step-by-step explanation:

Given are two triangles ABC and XYZ.

We have AB = XY = 25 cm, AC = YZ = 29 cm

and also angle A = angle X = 36 degrees

Thus we find that corresponding congruent sides are

AB and AC with angles A and X

To map ABC onto xyz,

Vertex B to Y, side AB to side XY with AC coinciding with XZ

Now all vertices x,y,z will perfectly match with transformed ABC
