Answer:
If the x is a multiplying sign then the answer is 6, but
if the x is the letter x then it will be x=4
First add like terms
53 = -14 + 7z
now add 14 to both sides
67 = 7z
divide both sides by 7
9.5714285 = z
i hope this helps!!
Step-by-step explanation:
We know that
- Area of the rectangle=Length×Breadth
➝(x+4)(x-9)=68
➝x(x-9)+4(x-9)=68
➝x^2-9x+4x+-32=68
➝x^2-5x-32=68
➝x^2-5x=68+32
➝x^2-5x=100
➝x^2-5x-100=0
- The equation has no real roots hence this situation can't be possible
Step-by-step explanation:
Oak tree -> 11 units
Garden-> 1 unit
Total-> 12 units which is 108 years
