If your 2 means "u squared" then
Just do 8-42=-34
The answer is -32u^2
I use ^ to show exponents
Hi there:)
I=prt
This is the formula of the simple interest
If you want to solve for p just divide each side by rt to get
P=I÷rt
Hope it helps

Answer:
n+p=21
Step-by-step explanation:
7n+7p=147si
7(10.5) +7(10.5)=147si
73.5+73.52=147si
Answer:
Step-by-step explanation:
P = 4x(x - 3) + 4y(y - 3) + 8xy
= 4x² - 12x + 4y² - 12y + 8xy
= (4x² + 8xy + 4y²) - (12x + 12y)
= 4(x² + 2xy + y²) - 12(x + y)
= 4(x + y)² - 12(x + y)
x+y =2 ⇒ P = 4.2² - 12.2 = 16 - 24 = -8
