What is the simplified expression for 5 a b + 9 a b minus a b?

aalyn [17]

Answer:

13ab

Step-by-step explanation:

When you add the 5 and 9 it will give you 14 but you still have to subtract the 1ab(there is a 1 in front of variables that don't have a visible number.) So it will be 13 a b.

A gallon of paint can cover 400 square feet. To the nearest half gallon, find how much paint will be needed to paint two coats o

nlexa [21]

I think that this is right, but I assumed that the ceiling has the same dimensions as the wall you would need 4 gallons for 2 coats.
Work:
20x8= 160 (square feet for 1 wall)
160x5=800 (i assumed there are 4 walls and 1 ceiling)
800x2=1600 (you need 2 coats)
1600/400=4 (each gallon includes 400 square feet)

Compute the special products. (-3+5i)2

sveticcg [70]

we are given

$(-3+5i)^2$

we can expand it

$(-3+5i)^2=(-3+5i)(-3+5i)$

now, we can FOIL it

$(-3+5i)^2=-3\times -3-3\times 5i+5i\times -3+5i\times 5i$

now, we can simplify it

$(-3+5i)^2=9-15i-15i+25i^2$

we know that

$i^2=-1$

so, we can plug it

$(-3+5i)^2=9-30i+25(-1)$

$(-3+5i)^2=9-30i-25$

$(-3+5i)^2=-16-30i$ ..............Answer
