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!
Answer:
C
Step-by-step explanation:
You can write the equation like this:
A - 2.5 = 1.5
If you reverse the equation, it looks like this:
1.5 - 2.5 = A
1.5 - 2.5 = 4
A = 4
16% of 231 is 36.80
16% + 84% = 100%
36.80+ 231 = $267.80
Ans = $267.80
The answer would be
D) 40
Answer:
24
Step-by-step explanation:
3.2x5 x1.5=24
Hope this helps :)
