First, try 99^3 = 970299; therefore, it is not the least possible value. 

The above number is a multiple of 99, so we can factor this out to find the least possible value. So we try to factor 99: 

99 = 9 * 11
99 = 3^2 * 11^ 1

and 3^3 * 11^3 = 35937

The least possible value is 4^1 + 11^2 = 125. Its sum is 125 which is a perfect cube.

Step-by-step explanation:

from what I can see there are 2 options to make the 2 triangles congruent :

either the opposite sides must be equal or the neighboring sides must be equal.

so, either

5x = 3x + 10

and

5x - 2 = 4x + 3

or

5x = 4x + 3

and

5x - 2 = 3x + 10

for the first

5x = 3x + 10

2x = 10

x = 5

control

5x - 2 = 4w + 3

5×5 - 2 = 4×5 + 3

23 = 23

correct.

for the second

5x = 4x + 3

x = 3

control

5×3 - 2 = 3×3 + 10

15 - 2 = 9 + 10

13 = 19

no, not a valid solution.

so, x = 5

What is the value of x?<br> A 5<br> B 2.5<br> C 7.5<br> D 10
RoseWind [281]

Answer:

A 5

Step-by-step explanation:

Parts on the left have the same ratio as parts on the right.

... x/(x+5) = (x -2)/(x +1)

Multiplying by (x+5)(x+1), we get

... x(x +1) = (x -2)(x +5)

... x² +x = x² +3x -10 . . . . eliminate parentheses

... 0 = 2x -10 . . . . . . . . . . subtract x²+x

... 0 = x -5 . . . . . . . . . . . . divide by 2

... 5 = x . . . . . . . . . . . . . . . add 5
