≈ r
Okay so first you want to simplify the given equation (7x+3y)(7x-3y)
in order to do this you multiply the first number of the first equation (7x) with the first number of the second equation (7x) this gives you 49x^2
Now you want to multiply the second number of the first equation (3y) by the second number of the second equation (-3y) this gives you -9y^2
Its as easy as pie!
He need to earn 48
Inequality : 80-32=x
Hello,
x²+2*7x+49+y²+2y+1+14-49-1=0
==>(x+7)²+(y+1)²=36
Center is (-7,-1) and radius 6.
