Answer:

45%

Step-by-step explanation:

The formula to work out the decrease is:

Percentage Decrease= actual decrease / original amount X 100%

1) So firstly, we have to work out the decrease, to do this we have to do is do $750-$412.50= $337.50

2) We can now substitute this into our formula which will now be. (We will also add the original amount, which is $750.00)

Percentage Decrease= 337.50 / 750.00 X 100% = 45

The percentage decrease is 45%

Expand c(3c - 3) I need help on this

Rudik [331]

$\\ \sf\longmapsto c(3c-3)$

Apply distributive law

a(b-d)=ab-ad

$\\ \sf\longmapsto 3c(c)-3(c)$

$\\ \sf\longmapsto 3c^2-3c$

We can still take common

$\\ \sf\longmapsto 3c(c-1)$

Multiply (5 + 3i)(5 − 3i) 16 + 15i 16 − 15i 16 34

Annette [7]

Answer:

(5 + 3i)(5 − 3i) = 34

Step-by-step explanation:

The multiplication of two identical binomials who have different symbol, can be solved using the factoring case of a difference of squares:

$(a-b).(a+b)=a^{2}-b^{2}$

So, in this case:

$(5+3i).(5-3i) = 5^{2}-(3i)^{2}$

$=25-9i^{2}$

Remember that $i=\sqrt{-1}$

So: $i^{2}=-1$

We replace on the polynomial:

$=25-9.(-1) = 25+9=34$
