Answer:
whenever you're multiplying terms that have exponents you multiply the coefficients and add their exponents:
Step-by-step explanation:
I think the answer to your first question should be:
30a²b - 30ab²
Your second answer is good
whenever you're multiplying terms that have exponents you multiply the coefficients and add their exponents:
for example, 6a²b³c x 2abc = 6(2)(a²)(a)(b³)(b)(c)(c)
= 12a³b⁴c²
To find the area you multiply l x w so, to find the sides you do the opposite, sq root of 24,200 (we can use the square root because we know it is a square and all sides are equal)=155.563492. This is only the length of one side. 155.563492*4=622.253968 which is a rational number.
The perimeter is a rational number.
Thousand - units, tens, hundreds, etc

2x+4y=16
2x+4(4)=16
2x+16=16
-16=-16=2x=0
Answer:
5
Step-by-step explanation:
64 = 4 + 12g
64 - 4 = 12g
60 = 12g
60 / 12 = g
5 = g
g = 5
