Answer:
Kirk wrapped 7 presents with those 23.8 cm of tape.
Step-by-step explanation:
Figure out the unit rate:
10.2 cm tape
-------------------
3 presents
or
3 presents
-----------------------
10.2 cm tape
Multiplying this by 23.8 cm results in the number of presents Kirk wrapped with that much tape:
(3 presents)(23.8 cm tape
--------------------------------------- = 7 presents
10.2 cm tape
Kirk wrapped 7 presents with those 23.8 cm of tape.
First find length. p=2(l+w)
32=2l+154
32-154=2l
-122=2l divide both sides by 2
l=-61
area=(l x w)
A=-61 x 77=-4697 square cm
Answer:
(s+16)(s-16)
Step-by-step explanation:
s^2-256
s^2-(16)^2
<u>a^2-b^2= (a+b)(a-b)</u>
<u />
(s+16)(s-16)
