A----------D----------C
AD = 2x + 6
DC = 4x - 7
the midpoint D splits AC into 2 equal parts....therefore, AD = DC
2x + 6 = 4x - 7
2x - 4x = -7 - 6
-2x = - 13
x = -13/-2
x = 6.5
DC = 4x - 7......4(6.5) - 7 = 19 <===
AD = 2x + 6.....2(6.5) + 6 = 19
8x2=16 and 11x2=22 all you have to do is add 16+22 and that gives you 38 i hope this helped
Answer:
-2
Step-by-step explanation:
trust me bro
10^[ 12 - ( - 3 ) ] = 10^( 12 + 3 ) = 10^15 ;
We use the formula
