Answer:the answer is b
Step-by-step explanation:
Let's solve your equation step-by-step.
1/3x^2=16
Step 1: Divide both sides by 1/3.
1/3x^2 ÷ 1/3 = 16 ÷ 1/3
x^2=48
Step 2: Take square root.
x=±√48
x=4√3 or x=−4√3
Answer: x=4√3 or x=−4√3
Ok so area=162
since the triangles sides were cut out of a square, base=height
area=1/2bh=162
b=h
area=1/2b^2=162
times 2 both sides
b^2=324
sqrt both sides
b=18=h
the legnth of one side is 18cm
see diagram
another way, is total aera of square=areas of both triangles=162+162=324
remember area of square=side^2 so
324=side^2
sqrt both sides
18=side
answer is 18cm
Answer:
A
Step-by-step explanation:
No others make sense because you can't use multiplication in this problem and well it's hard to explain honestly lol. But I'm almost certain your answer is A
