4d^-3 multiplyed by d^18

1 answer:

6 0

4*d^(-3)*d^18 = 4*d^(18-3) = 4*d^(15). The trick here is to combine the exponents.

Another way to write this problem would be:

4*d^18
---------- . Here d^18 divided by d^3 results in d^15, so again the final
d^3 answer is 4*d^15.

12x+12 because you do the distribution property and this is how 3*9=27 3*4x=12x 3*-5=-15 27-15 = 12 so 12x+12 would be the answer it is really simple.

Answer:

mary=10 jack=15

Step-by-step explanation:

After 4 years Mary (x+4), Jack's age (x+5) + 4.

sum of the ages after 4 years :(x+4) + (x+5) +4=33

Simplifying the equation:

2x+13 = 33 ----->> 2x=20----->>>>x = 10 Mary's age

10 + 5 = 15 which is Jack's age.

1. A square floor tile has an area of (x2 + 8x +16) in2. The side length of the tile is of the form cx + d, where c and d are wh

krok68 [10]

A) x2 + 8x + 16
= x2 + 4x + 4x + 16
= x(x+4) + 4(x+4)
= (x+4)(x+4) these are the equations of the two sides - they are the same because it is square. So the equation of one side is 1x + 4

b) The perimeter is the sides all added together, so that is
x+4+x+4+x+4+x+4 = x+x+x+x+4+4+4+4
= 4x+16 or 4(x+4)

c) When x=8 then the the perimeter is 4 lots of 8+4 inches which is 1 foot. 4 lots of 1 is 4, so the perimeter is 4 feet.

2) The difference of two squares can be written in the form x2 - y2. This can be written as (5n)2 -20, but because 20 is not a square number it can't be written as something-squared.
