The meaning of the question is
Let the unknown number be x
Therefore x+7=16-2x
Now 2x+x=16-7
3x=9
X=9/3
x=3
12 + v/5 = -3
step 1. subtract 12 from both sides...
v/5 = -15
step 2. Do the opposite operation, since your diving 5, multiply 5 and -15
v = -75
the variable 'v' equals -75
Answer:

Answer:

Step-by-step explanation:
Find the Area of the Rectangle which is = wl
Width = 17ft
Length = 22ft
17 × 22 = 374ft
Subtract 374ft by the area of the no digging
Width = 17ft
Length = 6ft
17 × 6 = 102ft
374 - 102 = 272ft
Answer:
12x^7+15x^6
Step-by-step explanation:
Change 3x^3-2 to 3x
(x^4)(3x)(4x^2+5x)
Multiply your single terms
(3x^5)(4x^2+5x)
Then distribute
12x^7+15x^6
