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:
-30
Step-by-step explanation:
move and divide -3/5 to the right side
-3/5x = 18
x=18÷(-3/5)
x= -30
Answer:
B
Step-by-step explanation:
3.2 * 10⁷ + 6.4 * 10⁷
= 10⁷ * (3.2 + 6.4)
= 10⁷ * 9.6
= 9.6 * 10⁷
The correct answer is D: $94,165.
First, let's find the amount of the down payment. It is 30% of the total.
310,000 x 0.30 = 93,000
Now, we just need to add on all the additional costs.
93000 + 100 + 250 +190 + 275 +70 + 280 = 94165
