If B is the midpoint of AC, solve for x, and find the lengths of AB, BC, and AC.

makvit [3.9K]

Answer:

49, 49 , 98

Step-by-step explanation:

AC = AB + BC = 2AB

3x - 31 = 2(x+6)
3x - 31 = 2x + 12
3x - 2x = 12 +31
x = 43

AB= BC = x + 6 = 43 + 6 = 49

AC = 2AB = 2* 49 = 98

Schaum earns (x4 + 16x) every month. His wife earns (3x4 + 11x) every

damaskus [11]

Given:

Schaum's earnings in a month = $x^4+16x$

His wife's earnings in a month = $3x^4+11x$

Where x is the number of working days in a month.

To find:

The total earnings in a month.

Solution:

We know that,

Total earnings = Schaum earnings + His wife's earnings in a month

$=x^4+16x+3x^4+11x$

$=(x^4+3x^4)+(16x+11x)$

$=4x^4+27x$

Therefore, the correct option is A.
