Answer:
14
Step-by-step explanation:
11 - n = -3
-n = -3 - 11 = -14
n = 14
OR
add n to both sides of equation and add 3 to both sides of equation:
11 - n + n + 3 = -3 + n + 3 ----> n = 14
Answer:
12:20
Step-by-step explanation:
i hope the answer will help you
L= length
w= width= L-3
A= area= 238 ft^2
LENGTH
Area Formula
A= LW
substitute w value
238= (L)(L- 3)
multiply L by parentheses
238= L^2 - 3L
subtract 238 from both sides
0= L^2 - 3L - 238
factor
0= (L + 14)(L - 17)
set each parentheses equal to 0
0= L + 14
-14= L
OR
0= L - 17
17 ft= L
*Since the measure of a rectangle would not be negative, L= 17 ft
WIDTH
w= L - 3
w= 17 - 3
w= 14 ft
ANSWER: Length= 17 ft; Width= 14 ft
Hope this helps! :)
the answer is 12ft by 20ft the last one i just took the quiz
Answer:
<h2><u><em>
C. between 4.4 and 4.6</em></u></h2>
Step-by-step explanation:
Because if you add 22 and 8 together you get 30 and once you get 30 you subtract 10 gaining 20 and then you divide 20 getting
.
22+8= 30
30-10= 20
![\sqrt{20} = 2\sqrt{5](https://tex.z-dn.net/?f=%5Csqrt%7B20%7D%20%3D%202%5Csqrt%7B5)
