Question:
Arectangle has a length of x + 2, a width of 7, and a perimeter of 32.
the value of x is
the value of x is
Answers
Perimeter= 2(l+w)
32= 2((x+2)+7)
32= 2x+4+14
32= 2x+18
14= 2x
7=x
Final x=7
P=2(L+W)
L=x+2
W=7
P=32
32=2(x+2+7)
32=2(x+9)
divide both sides by 2
16=x+9
minus 9 both sides
7=x
x=7 units
2 (x + 2) + 2 (7) = 32
2x + 4 + 14 = 32
2x + 18 = 32
2x = 32 - 18
2x = 14
2x ÷ 2 = 14 ÷ 2
x = 7
That other answer is just no it's 9
x=7
Step-by-step explanation:
Perimeter = sum of all sides
32 = 2(x+2) + 2(7)
32 = 2x+4 + 14
32 = 2x+18
14 = 2x
/2 /2
7 = x
The answer is x=7. Hope that helps
X would be 7.
collect like terms.
2x + 18 = 32
- 18
2x = 14
divide by 2
x = 7
X would have to equal 7, and here is my explanation as to why. If equal 0, the perimeter would be 18, not 32. The two lengths together would have to be 18, and you cann subtract the two additional 2's from it as we want to find x by itself. This shows that x would be 7, as 14/2 equals 7.
X=16
