Answer:

$4^5$

Thus, $4^2*4^3=4^5$

Answer:

Part a) The increase in dollars is $\$429$

ivolga24 [154]

The equation
y = mx + c
First let’s find m
m is the gradient
gradient is found with
rise/run

rise is the y run is x

Use the distributive property to remove the parentheses, simplify.

Nookie1986 [14]

Hi again :)

5b^3(4 - 9b^2)

Use the distributive property

=(5b^3)(4) + (5b^3)(-9b^2)

= 20b^3 - 45b^5

= -45b^5 + 20b^3

Have a nice day!
