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!
Absolute value, aka same distance from 0
for example |5| is five numbers away from zero and |-5| is also five numbers away from zero
9/10 * 5/2 = 45/20
The quotient will be greater than 1
So I think it would be $35 because if you multiply $3.50 by ten then it would be $35
Step-by-step explanation:
6,5:5,2=8:6,4 hope it helps
