Answer:
The product of these two numbers is 1239.
Step-by-step explanation:
Given that
a + b = 80
a - b = 38
Add both equation :
a + b = 80
a - b = 38
2a = 118
a = 59
Put value of a in any 1st equation
a + b = 80
b = 80 - 59
b = 21
<em>Product : </em>
a x b = 59 x 21
= 1239

i think its D. C. or E. I'm not that great in math im kind of struggling thru it
Answer:
[x+6y+2z][x²+(6y)²+(2z)²-6xy-12yz-2xz]
Step-by-step explanation:
x³+216y³+8z³-36xyz
x³+(6y)³+(2z)³-3×6×2×xyz
As we know
a³+b³+c³-3abc=(a+b+c)(a²+b²+c²-ab-bc-ca)
Let a=x
b=6y
c=2z
Now.
[x+6y+2z][(x²+(6y)²+(2z)²-x×6y-6y×2z-x×2z]
[x+6y+2z][x²+(6y)²+(2z)²-6xy-12yz-2xz]
