Answer:
x = 10
BD = 74
Step-by-step explanation:
Find x by setting 3x+7 equal to 37. Solve for x by subtracting 7 on both sides then divide by 3 to get x=10.
Since 37 is half of AC, multiply that by 2 to find AC or BD, which are the exact same length of 74.
Answer:
a=2^2
b=3^5
c=4^3x5^2
d=7^2x9^4
Step-by-step explanation:
All you have to do is write the number that is already there and power it by number of times it is repeated.
If there are two different numbers in a question (like c and d) you should start with the smaller number and then follow with the larger on with a x/times symbol between them.
