Answer:
Length = 21 cm
Width = 14 cm
Step-by-step explanation:
Let the width of the jewel case = m cm
So, the length of the case = (m + 7) cm
Area of the case = 
Now, Area of a Rectangle = Length x Width
= m x (m + 7)
⇒ m x (m + 7) = 294
or, 
⇒ 
or, 
⇒(m + 21)(m -14) = 0
Hence, either (m + 21) = 0 ⇒ m = -21
or, (m -14) = 0⇒ m = 14
Since, m is the width of a case, so it can not be negative
Hence the width of the jewel case = m = 14 cm
And the length of the case = (m + 7) = 14 + 7 = 21 cm
Answer:
85M + 4S <u><</u> 1000
Step-by-step explanation:
An inequality represents an expression that can have different values as long as the value is within the range given. In this case, the number of songs and movies that Caissa can download can not exceed 1000 MB. Since each move is 85 MB and each song is 4 MB, then any combination of these two files combined must not be larger than 1000 MB. Using the variable (M) for movies and (S) for songs, we can set up an expression 85M + 4S to represent the number of movies times 85 for each movie and the number of songs times 4 for each song. Since the total can be no greater than 1000, the expression would be less than or equal to (<u><)</u> 1000 MB.
Hey there,
Solution:
Fabric needed = 1 3 / 4
Fabric she has = 4 5 / 8
1 3 / 4 - make the denominator into 8
1 3 / 4 = 1 6 / 8
Fabric left = 4 5 / 8 - 1 6 / 8
= 37 / 8 - 14 / 8
= 23 / 8
= 2 7 / 8
Hope this helps :))

Answer:
x = -7/3 or -5
Step-by-step explanation:
3x^2 + 22x = -35
3x^2 + 22x + 35 = 0
(3x + 7) (x + 5) = 0
so for 3x+7:
3x+7 = 0
3x = -7
x = -7/3
So for x + 5:
x + 5 = 0
x = -5
Hi there and welcome to Brainly!
The answer to 8+(14+6) = 28. The reason for this is you add what is in parenthesis first then you add the number outside of the parenthesis. This follows the PEMDAS rule which is called the order of operations. PEMDAS is an acronym which stands for Parenthesis, Exponents, Multiplication/Division, and Addition/Subtraction, this is the order you should follow when solving any problem.
If you have anymore questions please feel free to ask them.
