Answer:
area= x^2+8x+7
Step-by-step explanation:
a=l*w
l=x+7
w=x+1
a=(x+7)(x+1)
a= x^2+8x+7
Answer:
Step-by-step explanation:

Thank you for posting your question here at brainly. The answer to the above question is the first one in the choices which is 15. Below is the solution:
<span>
3x + 10 = 55
Subtract 10 from each side...
3x = 45
Divide by 3...
x = 15</span>
You can form 2 and then you have the odd one out.
Log_3(x(x + 24) = 4
log_3(x^2 + 24x) = 4
3^4 = (x^2 + 24x)
81 = x^2 + 24x
x^2 + 24x - 81 = 0
Continue from here.
