<span>A = LW = 44
and
L = 3 + 2W
now substitute this into the first equation...
(3+2W)W=44
3W+2W^2=44

Rearranging
2W^2 + 3W - 44 = 0
Factoring we get
(2W + 11)(W - 4) = 0
so that
W = 4 inches
L = 11 inches</span>

Let width = x   then length  = 2x + 3

so area = 119 = x(2x + 3)

2x^2 + 3x - 119 = 0
(2x + 17)(x - 7)  
x = 7 , -8.5
so x = 7   ( -8.5 can be ignored)

What are the following numbers writen as powers? 243
puteri [66]

Answer:

243=3^5

Step-by-step explanation:

We have to write 243 as a power of some number.

So, if we factorize 243 we get,

243 = 3 × 3 × 3 × 3 × 3

Therefore, we can write 243 as a power of 3.

No other number can be written in powers of 243 because it do not contain any other factor than 3.

Hence, 243 can be written as :

243=3^5
