Answer:
12 x^5y^12
Step-by-step explanation:
3x^2y^5 * 4x^3y^7
Multiply the constants
3*4 = 12
Multiply the x terms
x^2 * x^3
We know a^b* a^c = a^(b+c)
x^(2+3) = x^5
Multiply the y terms
y^6 * y^7 = y&(5+7) = y^12
Put them back together
12 x^5y^12
width = w
length = w +2
perimeter = 2L + 2w
40 = 2(w+2) + 2w
40 = 2w+4 +2w
40 = 4w+4
36=4w
w=36/4 = 9
with = 9
length = 9+2 = 11
area = l x w = 9*11 = 99 square cm
A -3 subtracted by 10 is -13 and it stays 2
Answer:
the answer is 0.
Step-by-step explanation:
1/3(21) - 1 - 1/2(12) = 7 - 1 - 6 = 0
