Answer:
y=2x-3
Step-by-step explanation:
Answer:
inches
Step-by-step explanation:
Let the width be x.
Length = ![6+x](https://tex.z-dn.net/?f=6%2Bx)
Perimeter = Length + Length + Breadth + Breadth
Perimeter = ![(6+x)+(6+x)+x+x=48](https://tex.z-dn.net/?f=%286%2Bx%29%2B%286%2Bx%29%2Bx%2Bx%3D48)
![6+x+6+x+x+x=48](https://tex.z-dn.net/?f=6%2Bx%2B6%2Bx%2Bx%2Bx%3D48)
![4x+12=48](https://tex.z-dn.net/?f=4x%2B12%3D48)
Subtract 12 from both sides:
![4x+12-12=48-12](https://tex.z-dn.net/?f=4x%2B12-12%3D48-12)
![4x=36](https://tex.z-dn.net/?f=4x%3D36)
Divide both sides by 4:
![\frac{4x}{4}=\frac{36}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B4x%7D%7B4%7D%3D%5Cfrac%7B36%7D%7B4%7D)
(Width)
Length =
inches.
Answer:
(b + 3)(4b + 5)
Step-by-step explanation:
Given
4b² + 17b + 15
Consider the factors of the product of the b² term and the constant term which sum to give the coefficient of the b- term.
product = 4 × 15 = 60 and sum = 17
The factors are 12 and 5
Use these factors to split the b- term
4b² + 12b + 5b + 15 ( factor the first/second and third/fourth terms )
= 4b(b + 3) + 5(b + 3) ← factor out (b + 3) from each term
= (b + 3)(4b + 5) ← in factored form
Answer:
B. The system has no solution.
Step-by-step explanation:
[12x + 7y] = (20)
[12x + 7y] = (11)
The numbers in (parentheses) are both different while the numbers in the [brackets] are the same.
