Its D if you want to give it a shoot but im 75% sure is D hope you got it right. :)
If B is the midpoint of AC, then AB = BC.
We have AB = x + 5 and BC = 2x - 11.
Therefore we have the equation:
x + 5 = 2x - 11 <em>subtract 5 from both sides</em>
x = 2x - 16 <em>subtract 2x from both sides</em>
-x = -16 <em>change the signs</em>
x = 16
Put the value of x to the expression x + 5:
AB = 16 + 5 = 21
<h3>Answer: AB = 21</h3>
5^?=625^x, x=1/4
To rewrite in exponential form, the equation would be 5^?=625^x. From here, the bases need to be set equal. Since the fourth root of 625 is 5, the new equation becomes 625^1/4=625^x (625^1/4 is the same as the fourth root of 624). Now that the bases are the same, you can just solve for the variables, which become 1/4=x. Hope this helps :)
Answer:
8z+15
Step-by-step explanation:
Answer:
80cm^3
Step-by-step explanation:
To find the volume of the figure, we can see the shape comprises of both cube and cuboid
Volume of cuboid = length x breadth x height = 6x4x3= 72cm^3
Volume of cube = length xlength x length = 2×2×2 = 8cm^3
The volume of the figure = volume if cuboid and cube = 72+8 = 80cm^3
